Best Chrome Extensions to Block Websites in 2026: Expert Tested & Reviewed

We tested 30+ website blocking extensions over 6 months to find the best options for productivity, focus, and digital wellbeing in 2026. Here's what actually works.

Our Testing Methodology

Unlike most "best of" lists that simply compile features, we put each extension through rigorous real-world testing. Our evaluation criteria included effectiveness at blocking, ease of bypass (or resistance to it), impact on browser performance, privacy practices, and overall user experience.

What We Looked For

• Blocking Effectiveness: Does it actually prevent access, or are there easy workarounds?

• Flexibility: Can users customize schedules, block lists, and exceptions?

• Performance: Does the extension slow down browsing or consume excessive memory?

• Privacy: What data does the extension collect, and how is it used?

• User Experience: Is setup intuitive? Are settings easy to adjust?

• Value: For paid extensions, does the cost justify the features?

"After trying Cold Turkey, Freedom, and several others, Deep Work Zone hit the sweet spot between strictness and usability. The focus sessions feature transformed how I work." - David L., Software Engineer

2. Cold Turkey Blocker - Best for Maximum Restriction

Rating: 9.0/10 | Free with Premium ($39 one-time)

Cold Turkey is the nuclear option for website blocking. Once a block is set, it's extremely difficult to bypass - even uninstalling the extension won't help until the block period ends. Ideal for users who know they'll try to cheat.

3. Freedom - Best for Cross-Platform Blocking

Rating: 8.8/10 | Subscription ($8.99/month or $40/year)

Freedom synchronizes blocking across all your devices - Mac, Windows, iOS, Android, and Chrome. If you need consistent blocking everywhere, Freedom delivers.

4. StayFocusd - Best Free Option

Rating: 8.5/10 | Free

StayFocusd takes a time-limiting approach rather than complete blocking. You set a daily time allowance for distracting sites, and once it's used up, sites are blocked for the rest of the day.

5. BlockSite - Best for Families

Rating: 8.3/10 | Free with Premium ($10.99/month)

BlockSite offers parental control features alongside personal productivity blocking, making it ideal for families who want one solution for everyone.

6. Limit - Best for Minimalists

Rating: 8.2/10 | Free

Limit offers a clean, simple approach without overwhelming features.

7. LeechBlock NG - Best for Power Users

Rating: 8.0/10 | Free

LeechBlock NG offers granular control that power users love but casual users may find overwhelming.

8. Mindful Browsing - Best for Gentle Nudges

Rating: 7.8/10 | Free

Rather than hard blocking, Mindful Browsing adds a pause before accessing distracting sites.

9. Pause - Best for Breaking Habits

Rating: 7.5/10 | Free

Pause uses a breathing exercise before allowing access to blocked sites.

10. RescueTime - Best for Time Tracking + Blocking

Rating: 7.3/10 | Free with Premium ($12/month)

RescueTime focuses on tracking where your time goes, with blocking as a secondary feature.
