Best Website Blockers in 2026
You already know you waste too much time online. The stats haven’t changed: the average person spends over 2 hours a day on social media alone. What has changed is the tools available to fight back.
Website blockers in 2026 range from basic Chrome extensions to full browsers with blocking built into the engine. Some are easy to install but just as easy to disable. Others are genuinely hard to circumvent — which is the whole point.
We tested eight website blockers across macOS, Windows, and Chrome. We ranked them by one metric above all others: how hard they are to bypass when you’re trying to procrastinate. Because the best blocker is the one that still works when your willpower doesn’t.
This article is about the tools — what works, what doesn’t, and what you can actually trust when your willpower checks out.

1. Browwwser
Platform: macOS Price: $99/year or $199 lifetime Bypass difficulty: Very hard
Browwwser isn’t a browser extension or a background app that monitors your activity. It’s a standalone browser — built on Chromium — with website blocking baked into the browser engine itself.
When you block a site in Browwwser, the request never even starts loading. There’s no redirect page, no countdown, no “unblock for 5 minutes” button. The site simply doesn’t exist. On top of that, Browwwser monitors and closes macOS desktop apps you’ve blocked. If TikTok is on your blocklist, the desktop app gets killed too.
What makes it different
The core difference is architectural. Every other blocker on this list either runs as a browser extension (which can be disabled) or as a separate app that watches your browsers from the outside (which can be circumvented). Browwwser builds the block into the browser itself. There’s no extension to flip off in chrome://extensions, no background process to kill in Activity Monitor.
Other key features:
- Lock mode — lock your blocklist for 1 hour to 7 days, no override
- Scheduled blocking — automatically block social media during work hours
- One-click presets — block all social media, news, or video sites instantly
- Full Chrome import — bookmarks, passwords, extensions, history in one click
Limitations
Browwwser is macOS only. No Windows, no Linux, no iOS. And there’s no free tier — you’re paying for the software. If you’re on a budget or need cross-platform support, keep reading.
Who it’s for
People who have already tried extension-based blockers, found ways around them, and want something they genuinely can’t disable when the urge to scroll hits. If you’ve ever uninstalled a blocker extension at 11 PM “just for tonight,” Browwwser is built for you.
2. Cold Turkey
Platform: Windows, macOS Price: Free (basic) / $39 one-time (Pro) Bypass difficulty: Medium
Cold Turkey is the veteran of the website blocking space. It’s been around since 2012 and has a loyal user base, especially on Windows.
The free version lets you block websites and set timers. The Pro version adds application blocking, the ability to lock blocks so they can’t be turned off, and “Frozen Turkey” mode — which can lock your entire computer or force a shutdown.
How it works
Cold Turkey installs a desktop app that manages your blocklists. For browser-level blocking, it relies on browser extensions — one for each browser you use. You need to install and configure each extension separately, including enabling it for incognito/private mode.
The catch
The extension dependency is Cold Turkey’s biggest weakness. Extensions can be disabled, removed, or broken by browser updates. If you install a browser Cold Turkey doesn’t recognize, it has no extension for it. The app tries to detect and close unsupported browsers, but this is a reactive game, not a proactive block.
We wrote a full Cold Turkey vs Browwwser comparison if you want the detailed breakdown.
Who it’s for
Windows users who want a solid, one-time-purchase blocker with app blocking and a timer lock. If you’re on Windows, Cold Turkey Pro is the strongest option available.
3. Freedom
Platform: macOS, Windows, iOS, Android, Chrome Price: Free (limited) / $40/year Bypass difficulty: Medium
Freedom is the most cross-platform option on this list. It runs on macOS, Windows, iOS, Android, and as a Chrome extension. If you need blocking that follows you across devices, Freedom is worth considering.
Freedom works by creating “sessions” — time blocks during which selected sites and apps are blocked. You can schedule recurring sessions, and there’s a “locked mode” that prevents you from ending a session early.
How it works
On desktop, Freedom installs a system-level VPN or modifies your hosts file to block sites. On mobile, it uses a local VPN profile. In Chrome, it uses a browser extension.
The catch
Freedom’s blocking mechanism varies by platform, and some are weaker than others. The Chrome extension can be disabled. The VPN-based blocking on macOS can be circumvented by removing the VPN profile (unless locked mode is on). And on iOS, it’s limited to blocking Safari — other browsers and in-app browsers aren’t covered.
The locked mode helps, but it’s not as tight as Browwwser’s engine-level blocking or Cold Turkey’s Frozen Turkey mode.
Who it’s for
People who need blocking across multiple devices and operating systems. If you use an iPhone, a Windows laptop, and a Chromebook throughout the day, Freedom covers all three. Just know that the blocking strength varies by platform.
4. SelfControl
Platform: macOS Price: Free Bypass difficulty: Hard
SelfControl is a free, open-source macOS app that takes a simple approach: you add sites to a blocklist, set a timer, and hit start. Once active, the block cannot be undone — not by restarting the app, not by restarting your Mac, not by deleting the app.
How it works
SelfControl modifies your Mac’s system-level firewall rules. Once a block is active, the rules persist even through reboots. The only way to access a blocked site is to wait for the timer to expire.
The catch
SelfControl only blocks websites — not apps. It doesn’t have scheduling, presets, or any of the quality-of-life features that modern blockers offer. The UI is minimal to the point of being dated. And it only works on macOS.
It’s also a blunt instrument. There’s no “block social media but allow LinkedIn” — you manually add every domain you want to block.
Who it’s for
macOS users who want a dead-simple, free, no-nonsense blocker that’s extremely hard to bypass. If you don’t need app blocking, scheduling, or any bells and whistles, SelfControl is the most reliable free option on Mac.
5. Focus (by Meaningful Things)
Platform: macOS Price: Free (limited) / $20 one-time Bypass difficulty: Medium
Focus is a macOS productivity app that blocks websites and applications. It supports scheduling, a “Hardcore” mode that prevents you from disabling the block, and custom block pages with motivational quotes (if that’s your thing).
How it works
Focus modifies your Mac’s hosts file to block websites and uses process monitoring to close blocked apps. It integrates with the macOS menu bar for quick access.
The catch
Hosts file blocking has known limitations. It doesn’t work in all browsers under all configurations, and technically savvy users can edit the hosts file directly. The app blocking relies on repeatedly closing the app process, which can feel janky and sometimes has a delay.
Who it’s for
macOS users who want a lightweight, affordable blocker with basic scheduling and app blocking. It’s a solid middle ground between the simplicity of SelfControl and the full feature set of Browwwser.
6. LeechBlock
Platform: Chrome, Firefox Price: Free Bypass difficulty: Low
LeechBlock is a browser extension with extremely granular controls. You can set time limits, schedules, and different rules for different sites. It supports up to 30 separate block sets, each with its own schedule.
How it works
LeechBlock runs as a browser extension that intercepts web requests and blocks matching URLs based on your rules. It has a “lockdown” feature that temporarily blocks access to the extension’s settings.
The catch
It’s an extension. You can disable it in two clicks. You can open an incognito window where it doesn’t run (unless you explicitly enable it). You can open a different browser entirely. LeechBlock is powerful for people with mild distraction problems, but it relies entirely on your willingness to keep it installed.
Who it’s for
People who want detailed, granular control over their browsing habits and trust themselves not to disable the extension. LeechBlock is a tool for self-regulation, not self-enforcement.
7. BlockSite
Platform: Chrome, Android Price: Free (limited) / $36/year Bypass difficulty: Low
BlockSite is a popular Chrome extension and Android app for blocking websites. It has a clean interface, category-based blocking, and a “work mode” that blocks distracting sites on a schedule.
How it works
On Chrome, BlockSite runs as an extension that redirects you to a custom page when you try to visit a blocked site. On Android, it uses an accessibility service to detect and block apps and websites.
The catch
Same fundamental problem as every Chrome extension: it can be disabled. BlockSite also pushes users toward a paid subscription for basic features like unlimited blocklists. The free version is quite limited — you can only block a handful of sites.
The Android version requests broad accessibility permissions, which some users find concerning from a privacy perspective.
Who it’s for
Casual users who want a simple, visual Chrome extension to nudge themselves away from distracting sites. Not for anyone who needs serious, bypass-resistant blocking.
8. StayFocusd
Platform: Chrome Price: Free Bypass difficulty: Low
StayFocusd is one of the oldest Chrome blocking extensions, and it takes a unique approach: instead of outright blocking, it gives you a daily time allowance for distracting sites. Once you’ve used your allotted time, the sites are blocked for the rest of the day.
How it works
StayFocusd tracks the time you spend on sites you’ve flagged. Once your daily allowance runs out, it blocks access. It also has a “Nuclear Option” that blocks all sites on your list for a set period with no way to undo it (short of uninstalling the extension).
The catch
The “Nuclear Option” sounds strong, but you can still uninstall the extension. StayFocusd can make this slightly harder by requiring you to type a long passage of text before changing settings, but that’s a speed bump, not a wall.
Also, StayFocusd only works in Chrome. Open Firefox, Safari, or any other browser, and the blocks don’t apply.
Who it’s for
Chrome-only users who like the time-allowance model — “I can check Reddit for 10 minutes, then it’s gone.” If you respond well to budgets rather than hard blocks, StayFocusd is worth trying.
How to Choose a Website Blocker
The right blocker depends on two things: what platform you’re on and how seriously you need to block yourself.
If you’re on macOS and need something you can’t bypass:
Browwwser is the strongest option. The blocking is built into the browser engine. There’s no extension to disable, no process to kill, no workaround. It also blocks desktop apps and has lock mode, scheduling, and presets. It’s not free, but if you’ve tried other blockers and found ways around them, this is the endgame.
If you’re on Windows:
Cold Turkey Pro is the best choice. It has app blocking, a timer lock, and the Frozen Turkey nuclear option. Its extension-based browser blocking has known weaknesses, but on Windows, there’s nothing stronger available.
If you need cross-platform blocking:
Freedom covers macOS, Windows, iOS, Android, and Chrome. The blocking strength varies by platform, but the convenience of one tool across all devices is valuable.
If you want something free on Mac:
SelfControl is hard to bypass and costs nothing. It’s limited — no app blocking, no scheduling — but the core blocking is solid.
If you just want a Chrome extension:
LeechBlock gives you the most control. But remember: any extension-based blocker is only as strong as your decision to keep it installed.
Blocking distractions is always step one. The rest follows.
Frequently Asked Questions
What’s the hardest website blocker to bypass?
Browwwser is the hardest to bypass because the blocking runs inside the browser engine. There’s no extension to disable, no background process to kill, and no alternative browser to switch to during a locked session. SelfControl is a close second on macOS because it modifies system-level firewall rules.
Are free website blockers effective?
For mild distraction problems, yes. LeechBlock, SelfControl, and the free version of Cold Turkey all work. But free blockers are generally easier to bypass — especially browser extensions. If you’ve tried a free blocker and found yourself disabling it, you probably need a paid tool with stronger enforcement.
Do website blockers actually improve productivity?
The research says yes — but only if the blocking is consistent. A blocker you can disable in two clicks doesn’t change behavior. A blocker that makes accessing distractions genuinely difficult trains your brain to stop reaching for them. The friction is the feature.
Can I use a website blocker for my kids?
Most of the blockers on this list are designed for self-use, not parental controls. If you need to block sites for your kids, look into dedicated parental control software like Bark or Qustodio, which include monitoring, filtering, and device management features.
Do website blockers work on phones?
Freedom and BlockSite work on mobile devices. Freedom uses a local VPN on iOS and Android. BlockSite uses accessibility services on Android. Neither is as strong as desktop-level blocking, and iOS in particular limits what third-party apps can do. For serious mobile blocking, you’ll need to use Screen Time (iOS) or Digital Wellbeing (Android) in combination with a third-party blocker.
The Bottom Line
Website blockers exist on a spectrum. At one end: Chrome extensions that add a thin layer of friction. At the other end: a browser with blocking welded into the engine.
The right choice depends on how hard you need to be blocked. If a gentle nudge is enough, a free extension will do. If you need a wall — something you genuinely cannot get around when the craving hits — you need a tool where the blocking isn’t optional.
Whatever you pick, the act of choosing a blocker is already a step. The next step is making the block hard enough that future-you can’t undo it.
