A website blocker Chrome extension stops you opening distracting sites while you work. Some block a list of sites outright, some cap the time you spend on them, and some show you where your browsing time goes first. Eight are compared below, with the publisher and last update from each listing.
Five minutes on the news turns into forty, and the work you sat down to do is still waiting. A blocker in the browser is the quickest fix, because that's where most of the distraction lives.
The eight below are listed alphabetically, in no particular order, and the details come from each Chrome Web Store listing. If you want a plan for the hours you win back, my guide to productivity tools and time management techniques goes wider.
How these focus blockers made the cut
Each tool is a Chrome extension whose listing says it blocks or limits websites. From each Chrome Web Store listing we noted the publisher, users, rating and number of ratings, and the last updated date, as of Oct 2026. Nothing has been ranked. None of the eight listings says in its own text that the extension is free, so every free plan cell reads Not stated.

Eight website blockers for Chrome
Block Site
Best for: A no-frills blocklist of the sites you choose, and a separate extension from the bigger one whose name is written as one word.
BlockSite
Best for: Scheduled blocking with a password lock and a custom list, from the most installed blocker in this group.
FocusGuard
Best for: Highly rated blocking with a custom list and password protection, with the data line shown on its store listing.
Freedom
Best for: Taking control of distracting websites in Chrome, from Eighty Percent Solutions Corporation, whose listing also mentions an upgrade.
Simple Website Blocker
Best for: Trying a very small, simple blocker that shows the data line on its listing, with only a handful of ratings so far.
StayFocusd
Best for: Capping the time you spend on time-wasting sites rather than blocking them outright, from Sensor Tower.
StayFree
Best for: Seeing where your browsing time goes before you decide what to limit, and it's also published by Sensor Tower.
Web Site blocker
Best for: Keeping distracting sites shut while you work, from site-blocker.info, a smaller maker with a recent update on its listing.
Hard block, time limit or usage tracker
A hard blocker is the simplest: you add sites to a list and they won't open. Some add a schedule, so the block only runs in working hours, and a password, so you can't switch it off on a weak moment.
A time limit is gentler. Instead of shutting a site out, it caps how long you spend there, which suits sites you need for work but lose hours on. And a usage tracker shows you where your time goes before you decide what to limit.

Old blockers and the Manifest V3 switch
Google's Chrome for Developers site keeps a Manifest V2 support timeline, and it matters if you set up a blocker years ago and forgot about it. Manifest V2 was switched off on every Chrome channel with Chrome 138 on July 24, 2025, and all remaining Manifest V2 extensions were removed from the Chrome Web Store on August 31, 2026.
Want AI doing the heavy lifting in your marketing?
I build the systems that handle the boring 80 percent, so you get your week back. Done properly, with the human kept in.
Existing installs on Chrome 138 or earlier keep running, but they can't get updates and can't be reinstalled once removed. So an old blocker can sit in your toolbar looking fine while it quietly falls behind. Every blocker you can install from the store today is a Manifest V3 extension, so if yours isn't listed any more, swap it for one that is.
On privacy, three of the eight listings carry the line saying the developer will not collect or use your data, and the three with the most users don't show it in their listing text. A blocker sees every site you try to open, so read the Privacy practices box first.
Blocking whole sites is the blunt tool, and a comparison of Chrome ad blockers covers the lighter way to cut clutter on pages you still use.
Which blocker for which kind of distraction
- One or two sites eat your whole day: pick a hard blocker with a custom list and password protection.
- You need a site for work but lose hours on it: pick a time limit tool instead of a hard block.
- You don't know where your time goes: pick a usage tracker first, then add limits once you've seen the numbers.
- You want blocking only in working hours: pick one with scheduled blocking.
- You'll switch it off the moment it's annoying: pick one with a password lock, and give the password to someone else.
- You want the bare minimum: a simple blocklist with no extras will do.
If you're already cutting distractions, the other thing that makes long sessions easier is a darker screen, so see our list of dark mode extensions for Chrome.
Make the block stick
- Start with the two sites you lose the most time to, not twenty. A short list is easier to live with.
- Block them during your best working hours first, then widen it once you see it helping.
- Remember a browser extension only covers Chrome, so your phone is still one tap away.

My plain advice on browser blockers
Be honest about what distracts you. If it's a couple of sites, a hard blocker with a password does the job. If it's sites you need for work, a time limit works better than a wall. And if you've had the same blocker for years, check it's still in the store and still being updated.
Blocking is only half of it, so pair it with a plan for the time you win back. My energy mapping and time blocking cheat sheet helps with that, and my list of time tracking software shows where the time goes.

Frequently asked questions
What does a website blocker Chrome extension do?
It stops you opening the sites you choose in Chrome, or limits the time you spend on them, so you can focus on work.
Should I block a site or set a time limit?
Block sites you never need while working. Set a time limit on sites you need for work but tend to lose time on.
Are website blocker extensions free?
None of the eight listings here says in its own text that it's free, so the free plan column reads Not stated for all of them.
Will an old website blocker still work in Chrome?
Chrome for Developers says Manifest V2 extensions were removed from the store on August 31, 2026. Old installs on Chrome 138 or earlier keep running, but they get no updates.
Does a Chrome blocker work on my phone?
No. A Chrome extension only covers Chrome on your computer, so you'll need a separate app for your phone.
