Best Browser With a Built-In Website Blocker for Mac (2026)

Browwwser is, as far as we know, the only Mac browser with a website blocker built into the browser itself. The mainstream browsers leave blocking to something outside it: Safari uses macOS Screen Time, Chrome uses an admin policy, and most people install an extension they can switch off in five seconds.

If you want a block that holds when you’d rather be scrolling, the question isn’t which browser is fastest. It’s where the block lives, and who can undo it.

The 5 ways to block websites inside your browser on Mac

Option	Where the block lives	Undo it in a few seconds?	Price
1. Browwwser	Inside the browser	No, once locked	7-day trial, then $99/year or $199 once
2. Chrome + URLBlocklist policy	macOS policy, read by Chrome	No, needs admin rights	Free
3. Safari + Screen Time	macOS setting	Only with the Screen Time passcode	Free
4. Any browser + extension	Browser extension	Yes	Free to cheap
5. A system-wide blocker app	Operating system	Depends on the app	Free to paid

1. Browwwser: blocking built into the browser

Browwwser is a Chromium browser for macOS 12 and later. Blocking isn’t an add-on, so there’s nothing to disable on an extensions page. A blocked site doesn’t load. Browwwser shows a plain “site is blocked” page with a count of how many times it was blocked: no countdown, no “continue anyway” button.

• Lock mode freezes your blocklist behind a recovery password you choose. There’s no unlock button and no timer. If you forget the password, support sends a one-time recovery code within 24 hours.
• Schedules turn blocking on for recurring windows, such as work hours or evenings.
• Presets block social media, news, video or shopping sites in one click.
• App blocking closes the macOS apps you add, such as Discord or Steam, while blocking is active. Presets cover messaging, gaming, streaming and other browsers.
• Chrome import brings over bookmarks, passwords, history and extensions in one click, and Chrome extensions keep working.

The limit is the flip side of the design: Browwwser only blocks websites inside Browwwser. It works if it becomes your main browser. The Other Browsers preset can close Safari or Chrome while blocking is on; for a block that holds in every browser, pair it with a system-wide method.

2. Chrome with the URLBlocklist policy

Chrome has no “block this site” setting, but it reads policies set by the operating system. A site on the URLBlocklist doesn’t load, and nothing inside Chrome turns the block off. Google’s documentation allows up to 1,000 URLs. Setting it up takes a policy file and admin rights, so it’s built for IT departments rather than for self-control. There’s no schedule and no lock timer. Our Chrome guide walks through the setup.

3. Safari with Screen Time

Safari has no blocker of its own. macOS Screen Time fills the gap: go to System Settings › Screen Time › Content & Privacy and add the site to the Restricted list. Apple documents this restriction for Safari, not for other browsers. It’s free and already on your Mac. It holds as long as someone else keeps the Screen Time passcode; if you know it, you can undo the block yourself. More methods are in our guide on how to block websites on Mac.

4. Any browser with a blocking extension

Extensions such as LeechBlock NG, BlockSite and StayFocusd add a blocker to Chrome, Firefox, Edge or Brave in a minute. They’re free or cheap and good at schedules. Their weakness is structural: the extensions page is one click away, and turning the extension off ends the block.

5. A system-wide blocker app

Apps like SelfControl, Cold Turkey and Freedom run outside the browser and block sites in every browser on the Mac. SelfControl is free and keeps a block running until its timer ends, even after a restart. Cold Turkey Pro becomes very hard to undo once a block is locked. They’re the right choice if you switch between browsers all day.

Which one should you pick?

• You live in one browser and want the block to hold: Browwwser.
• You want a free, hard block in Chrome and don’t mind a policy file: Chrome’s URLBlocklist.
• You use Safari and someone else can hold the passcode: Screen Time.
• You only need a gentle nudge: an extension.
• You use several browsers every day: a system-wide app such as SelfControl or Cold Turkey.

Why we built blocking into the browser

Most blockers fail at the same moment: when you’d rather be distracted, the off switch is right there. An extension can be disabled from the extensions page, and a separate app can be quit when nothing is locked. Putting the blocker inside the browser removes that off switch from the place where you get distracted. That’s the whole idea behind Browwwser, and it’s also why it only makes sense if Browwwser is the browser you actually use.

Frequently asked questions

Does any Mac browser have a built-in website blocker?

Browwwser does. It's a Chromium browser for macOS where blocking is part of the browser, so there's no extension to switch off. Safari relies on Screen Time, a macOS setting. Chrome can block sites through its URLBlocklist policy, which is set from outside the browser with admin rights.

Can I block websites in Safari without an app?

Yes. Go to System Settings › Screen Time › Content & Privacy and add the site to the Restricted list. Apple documents this restriction for Safari, not for other browsers.

Is a browser extension enough to block websites?

For a nudge, yes. LeechBlock NG and similar extensions block sites on a schedule. But anyone can turn an extension off from the browser's extensions page in a few seconds, which is exactly when you need the block most.

What is the hardest website block to undo on a Mac?

SelfControl keeps a block running until its timer ends, even after a restart, in every browser. Inside a single browser, Browwwser's lock mode freezes the blocklist behind a recovery password you choose, with no unlock button and no timer.

Does Browwwser block websites in other browsers?

No. Browwwser only blocks sites inside Browwwser, so it works if you use it as your main browser. Its Other Browsers preset can close Safari, Chrome and other browsers while blocking is on. For a block that covers every browser, add a system-wide method such as the hosts file or SelfControl.
