# Top 10 Chrome Website Blocker Extensions: The Great Comparison > Compare the 10 best website blocker extensions for Chrome — LeechBlock NG, Cold Turkey, BlockSite, one sec and more — and how to block a site in Chrome. - Author: Marius Bongarts - Published: 2026-10-27 - Updated: 2026-10-27 - Tags: Chrome Extension, comparison, Productivity - Reading time: 23 min - URL: https://web-highlights.com/blog/best-website-blocker-chrome-extensions/ --- The best website blocker extension for Chrome is LeechBlock NG if you want whole sites gone. It’s free and open source, blocks on a schedule or after a time allowance, and scores 8.92/10 on Tooltivity. Cold Turkey Blocker (8.50) is the one you can’t switch off in the middle of a block, and BlockSite (8.40) is the most installed with 1,000,000 users, though its free version is limited. The top score in the category, Focused YouTube (9.17), doesn’t block anything: it strips YouTube down to a search bar. You open a new tab to look something up, and your fingers type the first letters of a site you didn’t mean to visit. A website blocker puts something between that reflex and the page: a block screen, a countdown, or just a moment to ask whether you meant it. The extensions in this category work in three different ways. Some block a site outright, on a schedule or after a daily allowance. Some pair with a desktop app, so the block holds even if you remove the extension. And some don’t block the site at all: they remove the feed, the recommendations or the Shorts and leave the rest of the page working. This comparison ranks the ten website blocker extensions with the highest Tooltivity scores on the Chrome Web Store. Read side by side, their listings and recent reviews show that the feature lists matter less than three other things: how easy each blocker is to switch off, what the free version still blocks, and what it does with your browsing. Two of the ten have also lost a lot of ground with their recent reviewers this year. ### Key takeaways - **LeechBlock NG** (8.92/10) is the best free blocker for whole sites: up to 30 sets of sites, each with its own schedule or time limit, and no paid tier at all. - **Cold Turkey Blocker** (8.50) is the strictest. Its listing warns that the browser may be blocked if you disable or remove the extension during a locked block. It needs its desktop app. - **one sec** (8.87) doesn’t block at all. It makes you take a breath before a distracting site opens. - **Only YouTube or a feed is the problem?** Focused YouTube (9.17), UnDistracted (8.83), FocusTube (8.75) and News Feed Eradicator (8.67) remove feeds, recommendations and Shorts and keep the sites usable. - **Read the recent reviews** – Web Activity Time Tracker’s last 100 reviews average 3.29, down from 4.71 in early May, after an update put ads into web pages, according to Tooltivity’s review. BlockSite’s slipped from 4.20 in July to 3.86. How this list was made: the scores come from [Tooltivity](https://tooltivity.com), a review site run by my company — the same one that makes Web Highlights. It rates each extension from its Chrome Web Store listing, its ratings and what recent reviews report, and this list is ordered by that score. I haven’t tested these ten hands-on, so the descriptions below summarize each listing, Tooltivity’s review and what users report. User counts and star ratings were read from the Chrome Web Store on October 27, 2026. The averages for the last 100 and last 500 reviews, and the trends since last winter, come from Tooltivity’s crawls of the store. Web Highlights isn’t in the list because it doesn’t block websites. ## How do I block a website on Chrome? Install a website blocker extension: Chrome has no setting that blocks a site in your own profile. Its site settings decide what a site may use, such as your camera, location, pop-ups or JavaScript, as [Google’s help page](https://support.google.com/chrome/answer/114662?hl=en) lists them. The two built-in ways to block a site are both meant for someone else to manage. [Family Link](https://support.google.com/families/answer/7087030?hl=en) lets parents allow or block specific sites for a child’s Google Account, although on Windows, Mac and Linux a child can sign out or switch profiles to leave those settings behind. And [Chrome Enterprise](https://support.google.com/chrome/a/answer/7532419?hl=en) lets admins block URLs on managed work and school browsers. For your own browser, it takes four steps: 1. Install a blocker from the Chrome Web Store. [LeechBlock NG](https://tooltivity.com/extensions/leechblock-ng) is free and handles schedules and time limits, [BlockSite](https://tooltivity.com/extensions/blocksite) is the quickest to set up, and [Cold Turkey Blocker](https://tooltivity.com/extensions/cold-turkey-blocker) is the one to pick if you always end up switching blockers off. 2. Add the site to its block list. A domain such as youtube.com is enough; LeechBlock NG also takes wildcards like \*.somesite.com. 3. Decide when the block applies: all the time, during set hours, or once you’ve used up a daily allowance. 4. Open Manage extensions, select **Details** on the blocker and turn on **Allow in Incognito**, as [Google’s extension help](https://support.google.com/chrome_webstore/answer/2664769?hl=en) describes, so a private window doesn’t skip the block. These are desktop extensions. On a phone, [one sec](https://tooltivity.com/extensions/one-sec) and [BlockSite](https://tooltivity.com/extensions/blocksite) also make apps, according to their listings. And if the trouble is one site’s feed rather than the whole site, read the section after the list first. ### List of the Best Website Blocker Extensions for Chrome: - [Focused Youtube](https://tooltivity.com/extensions/focused-youtube) - [LeechBlock NG](https://tooltivity.com/extensions/leechblock-ng) - [one sec](https://tooltivity.com/extensions/one-sec) - [UnDistracted - Hide Facebook, YouTube Feeds](https://tooltivity.com/extensions/undistracted) - [FocusTube: Block YouTube Shorts, Hide Recommendations & Distractions](https://tooltivity.com/extensions/focustube) - [Web Activity Time Tracker](https://tooltivity.com/extensions/web-activity-time-tracker) - [News Feed Eradicator](https://tooltivity.com/extensions/news-feed-eradicator) - [Cold Turkey Blocker](https://tooltivity.com/extensions/cold-turkey-blocker) - [DigitalZen - Block Websites & Stay Focused](https://tooltivity.com/extensions/digitalzen) - [BlockSite Block Websites & Stay Focused](https://tooltivity.com/extensions/blocksite) If you prefer a comparison overview, check out the [full comparison table of all Chrome website blocker extensions](https://tooltivity.com/extensions/compare/category/website-blocker/chrome): ![Comparison table of all Chrome website blocker extensions with Tooltivity ratings, user counts and store ratings](https://web-highlights.com/blog/content/images/2026/10/screenshot-website-blocker-comparison-extensions.webp) *Comparison of all Chrome Website Blocker Extensions* ## Can you block YouTube distractions without blocking YouTube? Yes. Four of the ten are built to hide the parts that keep you scrolling rather than block whole sites. [Focused YouTube](https://tooltivity.com/extensions/focused-youtube) turns YouTube’s homepage into a search bar, [FocusTube](https://tooltivity.com/extensions/focustube) gives every YouTube page its own switches and adds a hard block for work sessions, [UnDistracted](https://tooltivity.com/extensions/undistracted) covers eight sites including YouTube and can block them too, and [News Feed Eradicator](https://tooltivity.com/extensions/news-feed-eradicator) swaps the feed on twelve sites for a quote. They’re on this list because Tooltivity files them under website blockers, and because for many people a missing feed is easier to live with than a missing site. If you want the site gone, skip to [LeechBlock NG](#2-leechblock-ng), [Cold Turkey Blocker](#8-cold-turkey-blocker) or [BlockSite](#10-blocksite-block-websites--stay-focused). ## [1\. Focused Youtube](https://tooltivity.com/extensions/focused-youtube) ![YouTube’s homepage reduced to the logo and a single search bar by Focused YouTube](https://tooltivity.com/data/tooltivity/apps/focused-youtube/images/gallery-image-1.webp) Focused YouTube has 10,000 users and a 5.0-star rating on the Chrome Web Store from 704 ratings, and its recent reviews are almost as high, as evidenced by its 4.92 rating for the last 100 reviews. It also has Firefox and Edge versions. It’s the top score in this category, and it doesn’t block anything. Open YouTube and the homepage is a logo and a search bar. The column of suggestions next to the video is gone, comments and the description stay hidden until you ask for them, and Shorts stop showing up in the results. Search, your subscriptions and the video itself still work. That narrow job is why it scores so high. Tooltivity’s review read the package: it asks only for storage and access to YouTube, contains no tracker and makes no network requests, and the code is public on GitHub. What it doesn’t have is any way to hold you to it. There’s no schedule and no lock, and one switch in the popup turns it off. ### Key Features - **Search-only homepage** – YouTube’s home feed becomes a logo and a search bar, so you have to know what you came for - **No recommendations while watching** – the column of suggested videos next to the player disappears - **Comments on demand** – comments and the description are hidden by default, each with its own switch - **Shorts out of sight** – Shorts no longer appear between the search results - **Logo menu** – hovering the YouTube logo opens your subscriptions, history, playlists and liked videos - **Open source** – the code is public on GitHub, and the extension asks only for storage and YouTube access ### Pros & Cons **Pros:** - Completely free and open source - Homepage becomes a search bar - No setup needed - Only touches YouTube - No tracking, no network calls **Cons:** - No schedule or password lock - Sidebar can stay hidden when switched off - Hides live chat on streams - Firefox and Edge versions lag ### Who is this great for? Focused YouTube is perfect for anyone who uses YouTube for tutorials, lectures or music and keeps losing the evening to whatever it suggests next. It’s especially great for users who don’t want to set anything up. Install it, and YouTube is quieter the next time you open it. If YouTube has to disappear during work hours, pair it with a real blocker or use FocusTube’s hard block. ### Compared to others [FocusTube](https://tooltivity.com/extensions/focustube) does the same job with far more switches and adds a hard block, at the price of a busier popup and a paid plan for timed locks. [UnDistracted](https://tooltivity.com/extensions/undistracted) covers YouTube and seven other sites. [News Feed Eradicator](https://tooltivity.com/extensions/news-feed-eradicator) treats YouTube as one of twelve feeds and puts a quote in its place. ### Detailed comparisons [Focused YouTube vs FocusTube](https://tooltivity.com/extensions/compare/focused-youtube-vs-focustube) • [Focused YouTube vs UnDistracted](https://tooltivity.com/extensions/compare/focused-youtube-vs-undistracted) • [Focused YouTube vs News Feed Eradicator](https://tooltivity.com/extensions/compare/focused-youtube-vs-news-feed-eradicator) ### Rating Summary A 5.0 from 704 ratings is easier to hold with 10,000 users than with a million, but 4.92 across the last 100 reviews says it isn’t slipping. [Tooltivity](https://tooltivity.com) gave Focused Youtube a score of **9.17/10**. Check out the [full review here](https://tooltivity.com/extensions/focused-youtube). ## [2\. LeechBlock NG](https://tooltivity.com/extensions/leechblock-ng) ![LeechBlock NG’s block page saying the site has been blocked and when it will be unblocked](https://tooltivity.com/data/tooltivity/apps/leechblock-ng/images/gallery-image-1.webp) LeechBlock NG has 100,000 users and a 4.9-star rating on the Chrome Web Store from 1,598 ratings, and that score is holding, as evidenced by its 4.88 rating for the last 100 reviews and 4.88 across the last 500. It started on Firefox and also has an Edge version. This is the blocker for people who want to write their own rules. You sort sites into sets, up to 30 of them according to its listing, and give each set its own rule: blocked between 9am and 5pm, allowed for 10 minutes in every hour, or both. Lockdown blocks a set right now for as long as you enter, and a delaying page can put a countdown in front of a site instead of a wall. Everything is free. There’s no paid tier, no account and no upgrade prompt, and the code is open source; Tooltivity’s review read the package and found no tracking. The cost is the options page, a dense form with its own notation (a plus sign for exceptions, a tilde for keywords), and a look that hasn’t kept pace with newer tools. And like any extension, it can be removed in a weak moment. Its password and access codes only make that slower. ### Key Features - **Block sets** – up to 30 groups of sites, each with its own schedule, time limit and way of blocking - **Time periods and limits** – block within set hours, after an allowance such as 10 minutes an hour, or both - **Lockdown** – block chosen sets immediately for the hours and minutes you enter - **Delaying page** – a countdown, 60 seconds by default, in front of a site instead of a block - **Access control** – a password or a random code of up to 128 characters in front of the options - **Wildcards, exceptions and keywords** – block \*.somesite.com, allow +allowedsite.com, or block pages by keyword ### Pros & Cons **Pros:** - Completely free, no upsells - Open source, no trackers found - Separate rules per block set - Delay page instead of a wall - Password and access-code locks - Runs on Chrome, Firefox and Edge **Cons:** - Options page takes learning - Plain, dated interface - Can be removed like any extension - Statistics stay basic ### Who is this great for? LeechBlock NG is perfect for anyone whose distractions follow a pattern: news in the morning, social media after lunch, videos at night. Each pattern gets its own set. It’s especially great for users who want a free blocker they can shape exactly, and who don’t mind spending some time in the options once. ### Compared to others [BlockSite](https://tooltivity.com/extensions/blocksite) is easier to set up, but its free version stops at a few sites, according to its reviews; LeechBlock has no limit. [Cold Turkey Blocker](https://tooltivity.com/extensions/cold-turkey-blocker) is stricter, because its desktop app can close the browser if you remove the extension mid-block. [DigitalZen](https://tooltivity.com/extensions/digitalzen) also needs a desktop app for its strongest locks and asks for a subscription after its trial. ### Detailed comparisons [BlockSite vs LeechBlock NG](https://tooltivity.com/extensions/compare/blocksite-vs-leechblock-ng) • [Cold Turkey Blocker vs LeechBlock NG](https://tooltivity.com/extensions/compare/cold-turkey-blocker-vs-leechblock-ng) • [DigitalZen vs LeechBlock NG](https://tooltivity.com/extensions/compare/digitalzen-vs-leechblock-ng) ### Rating Summary 100,000 users, and 4.88 across both the last 100 and the last 500 reviews: about as steady as a scorecard gets. [Tooltivity](https://tooltivity.com) gave LeechBlock NG a score of **8.92/10**. Check out the [full review here](https://tooltivity.com/extensions/leechblock-ng). ## [3\. one sec](https://tooltivity.com/extensions/one-sec) ![A laptop showing one sec’s “It’s time to take a deep breath” screen in front of instagram.com](https://tooltivity.com/data/tooltivity/apps/one-sec/images/gallery-image-1.webp) one sec has 40,000 users and a 4.9-star rating on the Chrome Web Store from 1,188 ratings, and recent reviews remain high, as evidenced by its 4.78 rating for the last 100 reviews. That average has eased a little this year: Tooltivity’s crawl showed 4.97 in January. It also has Edge and Firefox versions. one sec doesn’t block anything in the usual sense either. When you open a site you’ve picked, it shows a short countdown and asks you to take a deep breath first. Its listing argues that a pause works on the habit itself, where most blockers only hold you back for a while. The delay is adjustable, down to one second if you only want the reminder, and a small dashboard shows how often you reached for each site. The listing also says all usage data stays offline on your device. The extension is free and simple, and Tooltivity’s review counts the small feature set as its main weakness. The same developer makes one sec apps for iPhone, iPad and Android, which block apps as well as websites, according to the listing. ### Key Features - **Pause before access** – a countdown and a breathing prompt before a distracting site opens - **Adjustable delay** – from a single second to several, for each site you choose - **Your own site list** – pick exactly which sites get the pause - **Attempts dashboard** – shows how often you tried to open each site during the day - **On-device data** – its listing says usage data is stored offline, on your device ### Pros & Cons **Pros:** - Simple and effective concept - Customizable delay and site list - Insightful analytics - Usage data stays on your device **Cons:** - Only delays, never blocks - Few functions next to full blockers - May not suit all browsing habits ### Who is this great for? one sec is perfect for anyone who opens social media out of reflex and would rather notice it than be locked out. It’s especially great for users who tried strict blockers and switched them off within a week. A pause is easier to keep than a wall. ### Compared to others [LeechBlock NG](https://tooltivity.com/extensions/leechblock-ng) has a similar delaying page as one option among many; one sec makes the pause the whole product. [Web Activity Time Tracker](https://tooltivity.com/extensions/web-activity-time-tracker) and [BlockSite](https://tooltivity.com/extensions/blocksite) block a site outright once you reach a limit. ### Detailed comparisons [LeechBlock NG vs one sec](https://tooltivity.com/extensions/compare/leechblock-ng-vs-one-sec) • [BlockSite vs one sec](https://tooltivity.com/extensions/compare/blocksite-vs-one-sec) • [one sec vs Web Activity Time Tracker](https://tooltivity.com/extensions/compare/one-sec-vs-web-activity-time-tracker) ### Rating Summary 40,000 users and a 4.9 from 1,188 ratings. The last-100 average has drifted from 4.97 to 4.78 since January and is still among the highest in this list. [Tooltivity](https://tooltivity.com) gave one sec a score of **8.87/10**. Check out the [full review here](https://tooltivity.com/extensions/one-sec). ## [4\. UnDistracted - Hide Facebook, YouTube Feeds](https://tooltivity.com/extensions/undistracted) ![UnDistracted’s switches for eight sites, from Facebook and YouTube to Reddit and LinkedIn](https://tooltivity.com/data/tooltivity/apps/undistracted/images/gallery-image-1.webp) UnDistracted has 80,000 users and a 4.8-star rating on the Chrome Web Store from 631 ratings, and recent reviews hold that level, as evidenced by its 4.77 rating for the last 100 reviews. It also has Edge and Firefox versions. UnDistracted leaves Facebook, YouTube, X, Reddit, Netflix, LinkedIn, Instagram and Pinterest open and removes the parts that keep you scrolling. Each site gets its own tab of switches for the feed, recommendations, Shorts, comments or Stories. Unlike the other feed removers here, it can also block a site outright, and the block list in its settings takes any other domain. Nearly all of it is free. A subscription adds a password lock, pauses on chosen weekdays, a gambling and NSFW filter and a few extra switches, according to Tooltivity’s review, which also read the package and found two permissions and no trackers. The price of hiding parts of a page is upkeep: when a site is redesigned, a single switch can stop working until the next update. ### Key Features - **Per-site switches** – separate tabs for eight sites, each with its own list of sections to hide - **Feed hiding** – remove the Facebook, LinkedIn and Instagram feeds or the X timeline and keep the rest - **YouTube controls** – hide recommendations, Shorts, comments and Up Next, or open on your subscriptions - **Site blocking** – a Block switch for every supported site, plus a block list for any other domain - **Redirect page** – blocked visits land on a quote, a breathing exercise, a to-do list or a URL you choose - **Timed pauses** – pause all filters for 5 to 30 minutes; they switch back on by themselves ### Pros & Cons **Pros:** - Hides feeds, keeps sites usable - Eight sites in one popup - Free version covers nearly everything - Two permissions, no trackers - Short pauses and a redirect page **Cons:** - Site redesigns break single switches - Password lock is paid only - No TikTok or Threads support - Reddit hiding needs old.reddit ### Who is this great for? UnDistracted is perfect for anyone who needs Facebook, LinkedIn or YouTube for work or study and loses time to the feed every time they go there. It’s especially great for users who want one popup for several sites, with the option to block the worst of them completely. ### Compared to others [News Feed Eradicator](https://tooltivity.com/extensions/news-feed-eradicator) covers more sites, twelve, but only hides feeds and never blocks. [FocusTube](https://tooltivity.com/extensions/focustube) goes much deeper on YouTube alone. [LeechBlock NG](https://tooltivity.com/extensions/leechblock-ng) is the free choice when you want the site gone, not tidied. ### Detailed comparisons [News Feed Eradicator vs UnDistracted](https://tooltivity.com/extensions/compare/news-feed-eradicator-vs-undistracted) • [FocusTube vs UnDistracted](https://tooltivity.com/extensions/compare/focustube-vs-undistracted) • [LeechBlock NG vs UnDistracted](https://tooltivity.com/extensions/compare/leechblock-ng-vs-undistracted) ### Rating Summary 80,000 users and a 4.8 from 631 ratings, with recent reviews at the same level. [Tooltivity](https://tooltivity.com) gave UnDistracted - Hide Facebook, YouTube Feeds a score of **8.83/10**. Check out the [full review here](https://tooltivity.com/extensions/undistracted). ## [5\. FocusTube: Block YouTube Shorts, Hide Recommendations & Distractions](https://tooltivity.com/extensions/focustube) ![YouTube’s homepage turned into a search bar by FocusTube’s distraction-free homepage mode](https://tooltivity.com/data/tooltivity/apps/focustube/images/gallery-image-1.webp) FocusTube has 8,000 users and a 4.6-star rating on the Chrome Web Store from 141 ratings, and recent reviews are a little warmer, as evidenced by its 4.72 rating for the last 100 reviews. It’s the smallest extension in this comparison. Where Focused YouTube gives you a handful of switches, FocusTube gives you a set for every YouTube page: Home, Subscriptions, Search, the watch page, channels and playlists. You can drop Shorts and the homepage feed but keep your subscriptions, or hide thumbnails on the homepage and keep them in search. The popup draws a small map of each page, so you see what a switch hides before you flip it. Unlike Focused YouTube, it can also shut YouTube off. Hard block mode sends YouTube to a focus screen, in every open tab or only in new ones, according to its listing. The core is free; timed locks need its Pro plan. Tooltivity’s review found no tracking and no network requests in the package, and notes that Shorts can creep back for a while after YouTube changes its layout. ### Key Features - **Per-page controls** – Home, Subscriptions, Search, the watch page, channels and playlists each get their own switches - **Shorts and Playables removal** – Shorts shelves, Shorts in search and YouTube Playables can all be hidden - **Watch page cleanup** – recommendations, comments, end cards and live chat can be switched off next to the video - **Visual page preview** – the popup shows which part of the page each switch hides - **Hard block mode** – one switch redirects YouTube to a focus screen - **Search-first homepage** – an optional layout turns the homepage into a search bar ### Pros & Cons **Pros:** - Separate controls for every page - Hides Shorts, Playables and comments - Visual preview of each switch - Hard block for focus time - No network calls or tracking - Core features free **Cons:** - Shorts can reappear after YouTube updates - Timed locks need Pro - Lock icons take getting used to - Hidden live chat leaves a gap ### Who is this great for? FocusTube is perfect for anyone who wants YouTube on their own terms: subscriptions yes, Shorts no, comments only where they help. It’s especially great for users who also want one switch that shuts YouTube off completely for a work session. ### Compared to others [Focused YouTube](https://tooltivity.com/extensions/focused-youtube) is simpler and asks nothing of you, but it can’t block. [UnDistracted](https://tooltivity.com/extensions/undistracted) spreads similar controls across eight sites. [LeechBlock NG](https://tooltivity.com/extensions/leechblock-ng) can block YouTube on a schedule without touching anything else. ### Detailed comparisons [Focused YouTube vs FocusTube](https://tooltivity.com/extensions/compare/focused-youtube-vs-focustube) • [FocusTube vs UnDistracted](https://tooltivity.com/extensions/compare/focustube-vs-undistracted) • [FocusTube vs LeechBlock NG](https://tooltivity.com/extensions/compare/focustube-vs-leechblock-ng) ### Rating Summary 8,000 users is the smallest base here, and a 4.72 average across the last 100 reviews says its newer reviewers like it a little more than the early ones. [Tooltivity](https://tooltivity.com) gave FocusTube: Block YouTube Shorts, Hide Recommendations & Distractions a score of **8.75/10**. Check out the [full review here](https://tooltivity.com/extensions/focustube). ## [6\. Web Activity Time Tracker](https://tooltivity.com/extensions/web-activity-time-tracker) ![Web Activity Time Tracker’s dashboard with a chart of the time spent on each website](https://tooltivity.com/data/tooltivity/apps/web-activity-time-tracker/images/gallery-image-1.webp) Web Activity Time Tracker has 30,000 users and a 3.4-star rating on the Chrome Web Store from 994 ratings, and its last 100 reviews average 3.29. In early May that average stood at 4.71, according to Tooltivity’s crawl. It fell within weeks of a May update and hasn’t recovered. It also has an Edge version. On paper it’s a time tracker first. It logs how long you spend on every site by itself, with no timer to start, and charts the result by day, week and month. You can set a daily limit for a site and have it blocked once the limit is used up, run a Pomodoro timer and export your data to CSV, all for free. The reviews tell a different story. According to Tooltivity’s review, an update in May 2026 asked for access to every website and then injected ad banners, many of them for gambling sites, into ordinary pages. It took about two months of one-star reviews before a new version removed them. The current version looks tamer: it no longer runs scripts on the sites you visit and keeps your tracking data in local storage. But the package still contains addresses on the same ad-tracking domain, and the short privacy policy doesn’t explain why. Tooltivity’s score is high because tracking and limits work well, while its mark for security and privacy is 6.5, the lowest single mark in this comparison. Read that mark before you install it. ### Key Features - **Automatic tracking** – time on every site is logged without a timer to start - **Reports** – daily, weekly and monthly charts of where your time went - **Limits and blocking** – set a daily limit for a site, and it is blocked once you reach it - **Custom alerts** – a warning when you spend too long on a site - **Pomodoro mode** – alternate work and rest periods - **CSV export** – take your data into a spreadsheet ### Pros & Cons **Pros:** - Easy to set up - Detailed activity reports - Many customization options - Free **Cons:** - Injected ads into websites this spring - Short privacy policy - No automatic categorization of websites - Recent reviews far below its history ### Who is this great for? Web Activity Time Tracker is perfect for anyone who first wants to know where the hours go, and only then decide what to block. It’s especially great for users who like charts and CSV exports. After this spring, check its permissions with every update. ### Compared to others [LeechBlock NG](https://tooltivity.com/extensions/leechblock-ng) and [BlockSite](https://tooltivity.com/extensions/blocksite) block more flexibly but track less. For the same kind of tracking without this history, Tooltivity’s review points to [TimeOWare](https://tooltivity.com/extensions/timeoware), which isn’t in this list. ### Detailed comparisons [BlockSite vs Web Activity Time Tracker](https://tooltivity.com/extensions/compare/blocksite-vs-web-activity-time-tracker) • [LeechBlock NG vs Web Activity Time Tracker](https://tooltivity.com/extensions/compare/leechblock-ng-vs-web-activity-time-tracker) • [one sec vs Web Activity Time Tracker](https://tooltivity.com/extensions/compare/one-sec-vs-web-activity-time-tracker) ### Rating Summary A 3.4 from 994 ratings and 3.29 across the last 100 reviews, down from 4.71 in May: the steepest fall in this comparison. [Tooltivity](https://tooltivity.com) gave Web Activity Time Tracker a score of **8.70/10**. Check out the [full review here](https://tooltivity.com/extensions/web-activity-time-tracker). ## [7\. News Feed Eradicator](https://tooltivity.com/extensions/news-feed-eradicator) ![A LinkedIn home page where News Feed Eradicator has replaced the feed with a quote](https://tooltivity.com/data/tooltivity/apps/news-feed-eradicator/images/gallery-image-1.webp) News Feed Eradicator has 200,000 users and a 4.5-star rating on the Chrome Web Store from 2,352 ratings, and its recent reviews are higher, as evidenced by its 4.71 rating for the last 100 reviews. It also has a Firefox version. News Feed Eradicator does what the name says: it deletes the feed and puts a quote where the scrolling used to be. Jordan West built the first version in 2012 to keep himself off the Facebook news feed, according to Tooltivity’s review, and it now covers twelve sites, from Facebook, Instagram, YouTube, X, Reddit and LinkedIn to Threads, Bluesky, Substack, GitHub and Hacker News. Messages, groups, search and profiles keep working. It never blocks a site. What it adds instead is friction around the feed: a snooze that brings feeds back for anything from a minute to 24 hours, an optional hold-to-snooze button that makes you hold for five seconds to get thirty seconds of feed, and a lock on its own settings. It’s free and open source, and Tooltivity’s review calls its permission set the smallest in the category: it asks for each site only when you switch that site on. The weak spot is the one every feed remover shares. A redesign can bring the feed back until the next update. ### Key Features - **Feed removal on 12 sites** – the home feed disappears while messages, search, groups and profiles work - **Region toggles per site** – hide parts such as YouTube’s suggestions sidebar or Instagram Stories - **Quote in place of the feed** – one of 83 built-in quotes, or your own lists - **Snooze** – bring the feeds back for one minute up to 24 hours - **Hold to snooze** – hold the button for five seconds to earn thirty seconds of feed - **Per-site permission** – asks for access to a site only when you switch it on ### Pros & Cons **Pros:** - Free and open source - Sites stay usable without feeds - Access only to chosen sites - Hold-to-snooze adds real friction - Region toggles for each site **Cons:** - Breaks when sites change layout - No custom sites, no TikTok - Snooze reopens every site - Mobile site versions not covered ### Who is this great for? News Feed Eradicator is perfect for anyone who needs social sites for messages, groups or work and wants the feed out of the way. It’s especially great for users who want a free tool that asks for as little access as possible. ### Compared to others [UnDistracted](https://tooltivity.com/extensions/undistracted) covers fewer sites but can block them outright. [Focused YouTube](https://tooltivity.com/extensions/focused-youtube) does a deeper clean-up of YouTube alone. [LeechBlock NG](https://tooltivity.com/extensions/leechblock-ng) is the free choice if you want the site gone. ### Detailed comparisons [News Feed Eradicator vs UnDistracted](https://tooltivity.com/extensions/compare/news-feed-eradicator-vs-undistracted) • [Focused YouTube vs News Feed Eradicator](https://tooltivity.com/extensions/compare/focused-youtube-vs-news-feed-eradicator) • [LeechBlock NG vs News Feed Eradicator](https://tooltivity.com/extensions/compare/leechblock-ng-vs-news-feed-eradicator) ### Rating Summary 200,000 users and 2,352 ratings make it one of the most used tools here, and it has done the same job since 2012. [Tooltivity](https://tooltivity.com) gave News Feed Eradicator a score of **8.67/10**. Check out the [full review here](https://tooltivity.com/extensions/news-feed-eradicator). ## [8\. Cold Turkey Blocker](https://tooltivity.com/extensions/cold-turkey-blocker) ![Cold Turkey Blocker’s dark block screen reading “This website is blocked” above a quote](https://tooltivity.com/data/tooltivity/apps/cold-turkey-blocker/images/gallery-image-1.webp) Cold Turkey Blocker has 300,000 users and a 4.6-star rating on the Chrome Web Store from 2,358 ratings, and recent months have been slightly better, as evidenced by its 4.65 rating for the last 100 reviews. It also has an Edge version. Cold Turkey is the strict one. The extension does nothing alone: its listing says it is to be used only with the Cold Turkey desktop app. The app, for Windows and macOS, holds your block lists, timers and locks. Once you lock a block, you can’t edit the list, disable the extension or uninstall the app until the timer ends. The listing puts the warning first: the browser may be blocked if the extension is disabled or removed during a locked block. That strictness is the point, and it has a cost. Setup means a desktop app, the extension in every browser and profile, and access to private windows. Tooltivity’s review notes that when the app’s check misfires, it closes the browser on you. The free version blocks as many sites as you like, with timed blocks you can lock; schedules, allowances and app blocking are part of Pro, which is a one-time purchase rather than a subscription, according to the same review. The listing says data collected by the extension never leaves your computer. ### Key Features - **Block lists for sites, pages and patterns** – a whole domain, a single page such as one subreddit, or a wildcard - **YouTube channel rules** – block single channels, or allow only the channels you pick - **Keyword and category blocks** – stop searches with certain words, or block everything except your exceptions - **Locked blocks** – while a block is locked, the list, the extension and the app can’t be changed - **Tamper protection** – the desktop app closes the browser if the extension is removed during a locked block - **Scheduled blocks (Pro)** – draw blocks onto a weekly calendar that repeats on its own ### Pros & Cons **Pros:** - Locked blocks cannot be undone - Generous free version - Pro is a one-time purchase - Blocks channels, keywords and apps - No tracking code in the package **Cons:** - Needs the desktop app - No phone or tablet version - Can close the browser by mistake - Setup takes patience ### Who is this great for? Cold Turkey Blocker is perfect for anyone who has switched off every blocker they’ve tried. It’s especially great for users on Windows or macOS with a deadline they can’t talk themselves out of: an exam week, a thesis chapter, a launch. ### Compared to others [DigitalZen](https://tooltivity.com/extensions/digitalzen) works the same way with a desktop app, adds Linux, and needs a subscription after its trial. [LeechBlock NG](https://tooltivity.com/extensions/leechblock-ng) is free and lives entirely in the browser, which makes it easier to set up and easier to remove. [BlockSite](https://tooltivity.com/extensions/blocksite) is far simpler, and its reviewers say its password lock can be bypassed. ### Detailed comparisons [Cold Turkey Blocker vs DigitalZen](https://tooltivity.com/extensions/compare/cold-turkey-blocker-vs-digitalzen) • [BlockSite vs Cold Turkey Blocker](https://tooltivity.com/extensions/compare/blocksite-vs-cold-turkey-blocker) • [Cold Turkey Blocker vs LeechBlock NG](https://tooltivity.com/extensions/compare/cold-turkey-blocker-vs-leechblock-ng) ### Rating Summary 300,000 users and a 4.6 from 2,358 ratings, with the last 100 reviews at 4.65. [Tooltivity](https://tooltivity.com) gave Cold Turkey Blocker a score of **8.50/10**. Check out the [full review here](https://tooltivity.com/extensions/cold-turkey-blocker). ## [9\. DigitalZen - Block Websites & Stay Focused](https://tooltivity.com/extensions/digitalzen) ![DigitalZen’s store graphic “Block websites” in front of its block screen](https://tooltivity.com/data/tooltivity/apps/digitalzen/images/gallery-image-1.webp) DigitalZen has 10,000 users and a 4.9-star rating on the Chrome Web Store from 151 ratings, as evidenced by its 4.96 rating for the last 100 reviews, in line with its all-time average. It also has a Firefox version and a small Edge one. DigitalZen is a cross-platform blocker, and this extension is its browser half. With the DigitalZen desktop app on Windows, macOS or Linux, the extension checks every page against the app over a local connection, and the app can also block desktop programs and browsers that don’t have the extension. Without the app, the extension still blocks sites, sets daily limits and runs focus sessions that allow only the sites you picked; its listing says it works on its own or with the app. Its lock modes add friction before you can end a block: an unlock delay, a long code to type out, or a code sent to someone else’s email. Two things hold the score back, according to Tooltivity’s review. After a 7-day trial, most of it needs a subscription. And a large part of its Chrome reviews arrived in one short burst at launch, many of them short and alike, so the near-perfect rating carries less weight than it seems. ### Key Features - **Desktop app companion** – with the app on Windows, macOS or Linux, every page is checked against your rules - **Website and category blocking** – block single sites or whole categories, or give a site a daily limit - **Focus sessions** – allow only the sites and apps you picked until the timer runs out - **Schedules and breaks** – recurring blocks and breaks, plus allowances that start a block after a set time - **Lock modes** – an unlock delay, a long code to type, or a code sent to someone else - **Blocking templates** – ready-made rules such as “Block news sites” that you can switch on and edit ### Pros & Cons **Pros:** - Desktop apps for Windows, macOS and Linux - Blocks are hard to switch off - Focus mode with allowlist - Ready-made blocking templates - Student discount available **Cons:** - Subscription after 7-day trial - Strongest blocking needs desktop app - No phone app yet - Edge version barely used ### Who is this great for? DigitalZen is perfect for anyone who needs the block to cover the whole computer, not just Chrome, including Linux, where it has few rivals. It’s especially great for users who want a lock that involves another person, and who don’t mind a subscription. ### Compared to others [Cold Turkey Blocker](https://tooltivity.com/extensions/cold-turkey-blocker) is the closest match: a desktop app with locks and a one-time Pro purchase, but no Linux. [LeechBlock NG](https://tooltivity.com/extensions/leechblock-ng) is the free in-browser alternative. [BlockSite](https://tooltivity.com/extensions/blocksite) is the easier start if you only need Chrome. ### Detailed comparisons [Cold Turkey Blocker vs DigitalZen](https://tooltivity.com/extensions/compare/cold-turkey-blocker-vs-digitalzen) • [DigitalZen vs LeechBlock NG](https://tooltivity.com/extensions/compare/digitalzen-vs-leechblock-ng) • [BlockSite vs DigitalZen](https://tooltivity.com/extensions/compare/blocksite-vs-digitalzen) ### Rating Summary 10,000 users and a 4.9 from 151 ratings, with 4.96 across the last 100 reviews. [Tooltivity](https://tooltivity.com) gave DigitalZen - Block Websites & Stay Focused a score of **8.42/10**. Check out the [full review here](https://tooltivity.com/extensions/digitalzen). ## [10\. BlockSite Block Websites & Stay Focused](https://tooltivity.com/extensions/blocksite) ![BlockSite’s block list with twitter.com, facebook.com and netflix.com locked](https://tooltivity.com/data/tooltivity/apps/blocksite/images/gallery-image-1.webp) BlockSite has 1,000,000 users and a 4.5-star rating on the Chrome Web Store from 32,432 ratings, though recent sentiment has slipped below that, as evidenced by its 3.86 rating for the last 100 reviews. In July, Tooltivity’s crawl showed 4.20. BlockSite is the best-known blocker in the category and the most installed by far. Its feature list is the longest: a block list by site, category or keyword, scheduled blocking, a focus timer, an adult-content filter, a password lock, a custom redirect and insights into how often you tried to open a blocked site. Its listing also announces a usage limit that blocks a site for the rest of the day once you reach your time cap. The catches come up again and again in its reviews, according to Tooltivity’s review. The free version blocks only about three sites before the upgrade prompt. New users are asked to agree to data collection, and declining leaves the extension largely unusable. Reviewers also found ways around the password lock and report that blocking is unreliable in Incognito and in Brave. Those complaints are behind the slide in its recent rating. ### Key Features - **Custom block list** – block any site by URL, or whole categories and keywords at once - **Scheduled blocking** – set the hours and days when chosen sites are off-limits - **Usage limit** – a daily time cap per site, after which it stays blocked for the day - **Focus mode** – a Pomodoro-style timer that blocks distractions during work cycles - **Password protection** – lock your block settings behind a password - **Custom redirect** – send blocked visits to a page you choose ### Pros & Cons **Pros:** - Polished, easy-to-use interface - Scheduling, focus mode and password lock - Blocks categories and keywords - Block list syncs across devices **Cons:** - Free tier blocks only about three sites - Frequent upgrade prompts - Requires a data opt-in - Password lock can be bypassed - Unreliable in Incognito and Brave ### Who is this great for? BlockSite is perfect for anyone who wants a blocker that looks good and works in a few clicks, and who is willing to pay to block more than a handful of sites. It’s especially great for users who want the same block list on several devices; the sync needs an account. ### Compared to others [LeechBlock NG](https://tooltivity.com/extensions/leechblock-ng) does most of what BlockSite’s paid plan does, for free, with a plainer interface. [one sec](https://tooltivity.com/extensions/one-sec) is the gentler option if a pause would do. [Cold Turkey Blocker](https://tooltivity.com/extensions/cold-turkey-blocker) is the one to pick if BlockSite’s password lock is too easy to get around. ### Detailed comparisons [BlockSite vs LeechBlock NG](https://tooltivity.com/extensions/compare/blocksite-vs-leechblock-ng) • [BlockSite vs Cold Turkey Blocker](https://tooltivity.com/extensions/compare/blocksite-vs-cold-turkey-blocker) • [BlockSite vs one sec](https://tooltivity.com/extensions/compare/blocksite-vs-one-sec) ### Rating Summary 1,000,000 users and 32,432 ratings are the biggest numbers here, but the last 100 reviews average 3.86, down from 4.20 in July. [Tooltivity](https://tooltivity.com) gave BlockSite Block Websites & Stay Focused a score of **8.40/10**. Check out the [full review here](https://tooltivity.com/extensions/blocksite). ## Why isn’t StayFocusd on the list? Because it scores 7.58 on Tooltivity, below all ten. [StayFocusd](https://tooltivity.com/extensions/stayfocusd-website-blocker-and-focus-timer), made by Sensor Tower according to its listing, has 700,000 users and a 4.4-star rating from 8,796 ratings. But its last 100 reviews average 3.35, down from 4.65 in December 2025, according to Tooltivity’s crawl, and Tooltivity’s review puts the slide down to a block-list bug and privacy concerns. It still has the Nuclear Option, which its listing says blocks sites for the hours you set and can’t be cancelled once it’s on. ## Which website blocker should you choose? On Tooltivity’s score the winner is **[Focused YouTube](https://tooltivity.com/extensions/focused-youtube)** at 9.17/10, and if YouTube is where your time goes, it’s the easiest fix on this list: free, open source and nothing to set up. But it doesn’t block anything. For a blocker in the full sense, **[LeechBlock NG](https://tooltivity.com/extensions/leechblock-ng)** (8.92) is the pick: free, no account, and flexible enough for almost any rule. An average of 4.88 across its last 100 and last 500 reviews says people stay with it. The rest sorts by how strict you need it to be. **[one sec](https://tooltivity.com/extensions/one-sec)** is the gentle option, a breath before the site opens. **[UnDistracted](https://tooltivity.com/extensions/undistracted)**, **[FocusTube](https://tooltivity.com/extensions/focustube)** and **[News Feed Eradicator](https://tooltivity.com/extensions/news-feed-eradicator)** keep the sites and remove the feeds. **[BlockSite](https://tooltivity.com/extensions/blocksite)** is the easiest start if you can live with its free limit. **[Cold Turkey Blocker](https://tooltivity.com/extensions/cold-turkey-blocker)** and **[DigitalZen](https://tooltivity.com/extensions/digitalzen)** are for when you know you’ll switch an extension off: their desktop apps make the block hold. Two warnings. **[Web Activity Time Tracker](https://tooltivity.com/extensions/web-activity-time-tracker)** injected ads into web pages this spring, according to Tooltivity’s review, and its recent reviews still average 3.29. And whatever you install, turn on Allow in Incognito, or a private window walks straight past it. Every extension here installs free, so pick two, give them a week and keep the one you don’t switch off. [The full comparison table](https://tooltivity.com/extensions/compare/category/website-blocker/chrome) has all fourteen of Tooltivity’s website blockers side by side. A blocker clears the way; it doesn’t decide what you read once you’re there. If cluttered pages are the problem, a [reader mode extension](https://web-highlights.com/blog/top-5-reader-mode-chrome-extensions-for-focused-reading/) strips them down, and there’s a separate list of [productivity extensions that don’t need AI](https://web-highlights.com/blog/top-5-non-ai-productivity-chrome-extensions-everyone-needs-to-know/). Students will find more in the [best Chrome extensions for students](https://web-highlights.com/blog/best-chrome-extensions-for-students/). ## Frequently asked questions ### What’s the best free website blocker for Chrome? LeechBlock NG. It has no paid tier and no account, the code is open source, and it blocks up to 30 sets of sites on a schedule, after a time allowance or both. Tooltivity scores it 8.92/10. If you’d rather be slowed down than locked out, one sec’s extension is free too and puts a pause before the site opens. BlockSite is free to install, but its reviewers say the free version stops at about three sites. ### Is there a website blocker you can’t just turn off? Cold Turkey Blocker comes closest. While a block is locked, you can’t edit the list, disable the extension or uninstall its desktop app, and its listing warns that the browser may be blocked if the extension is removed. DigitalZen’s desktop app adds lock modes such as an unlock delay or a code sent to someone else. Blockers that live only in the browser, like LeechBlock NG, can hide their settings behind a password, but they can still be removed.
