The 6 Best Website Blockers for Windows in 2026
Ranked by bypass resistance, features, platforms and price · Updated
The best website blocker for Windows is one that enforces below the browser, not just inside it. System-level blockers like Ascension, Cold Turkey and FocusMe cover every browser at once and keep working after you close the app, which makes them much harder to bypass than browser extensions like StayFocusd or LeechBlock. This guide ranks six of the best by bypass resistance, features, platforms and price.
Key takeaways
- System-level coverage: System-level blockers cover the whole computer; extensions cover one browser. Ascension, Cold Turkey and FocusMe enforce below the browser and keep working after you close the app.
- Bypass resistance is the ranking: Ascension, Cold Turkey and FocusMe are the hardest to bypass. Browser extensions can be removed in seconds.
- Only Freedom covers your iPhone: one session syncs across Windows, Mac, iOS and Android. FocusMe adds Android; the rest are desktop or browser only.
- Pricing ranges from free to paid desktop tools: LeechBlock and StayFocusd are free, Cold Turkey is a one-time purchase, and Ascension, Freedom and FocusMe offer both subscriptions and one-time licences.

Finding the right website blocker
Browser extensions work for casual use, but they cover only one browser and can be removed. For enforcement that covers every browser and keeps working after you close the app, you need a system-level blocker.
On Windows, that comes down to Ascension and Cold Turkey. Cold Turkey is the better fit if you want to block apps. Ascension is the better fit if you want equally strict blocking and deep analytics in the same app. If your iPhone is as much of a distraction as your PC, Freedom is the only option here that covers both.
Frequently asked questions
Does Windows have a built-in website blocker?
Not a real one for adults. Windows lets you block sites by editing the hosts file, but that is manual and takes seconds to undo, and Microsoft Family Safety is built to restrict a child's account, not to help you restrict yourself. For self-control on your own PC, a dedicated blocker is the practical option.
How do I block a website permanently on Windows?
Editing the hosts file is not permanent, since you can reverse it at any time. A dedicated blocker that cannot be bypassed is the solution. Ascension lets you block any content on the web, then decide what level of friction to attach to it, from removable and easy all the way to impossible. Switching browsers or trying to uninstall Ascension will not work.
Which website blocker is hardest to bypass?
On Windows, Ascension, Cold Turkey and FocusMe. All three enforce at the system level and keep working after the app is closed, unlike browser extensions. Cold Turkey blocks the Task Manager and system time changes. FocusMe's Enforced Mode cannot be overridden once a plan is running. Ascension's strongest lock cannot be removed until it expires, and it closes any browser running without its extension.
Is there a free website blocker for Windows?
Yes. LeechBlock NG and StayFocusd are free browser extensions that work well for casual focus. They work inside one browser and can be disabled, so they are used to create friction rather than guarantee full blocking.
Can website blockers block desktop apps?
Yes. Cold Turkey, Freedom and FocusMe block desktop apps.
Available on Windows 10 & 11
