Cold Turkey vs. Freedom vs. BlockSite: Which Windows Blocker Actually Works?

Most blockers work fine until the moment you actually want to bypass them. That is the only moment that matters. Here is an honest look at the main options for Windows — what each one does, and what happens when you push against it.

Browser extensions: BlockSite, StayFocusd, LeechBlock

Browser extensions are where most people start. They are free, easy to set up, and good enough for mild distraction — the kind where a small nudge is all you need to redirect yourself. For that use case, something like StayFocusd or LeechBlock is perfectly reasonable.

The problem is structural: they live inside the browser, which means you control them completely. Switch browsers, open an incognito tab, or spend thirty seconds uninstalling the extension. Block gone. Anyone with a real history of bypassing their own rules will find their way around a browser extension almost immediately.

Freedom

Freedom is a meaningful step up. It runs as a background service, blocks at the network level, works across all browsers, and syncs across devices including iPhone — which is genuinely useful if you are trying to maintain consistent rules everywhere at once.

On normal days, it holds. The friction is real enough that casual bypass attempts tend not to happen. I used Freedom for a while and it helped more than any browser extension had.

The weakness on Windows: a determined user can still stop the background service, uninstall the app, or boot into safe mode. It takes more effort than removing an extension, but it is not structurally prevented. The bad days — when you most need the block — are often the same days you are most motivated to find a workaround.

Cold Turkey Blocker Pro

Cold Turkey Pro is the only Windows blocker where a locked block genuinely cannot be removed mid-session. When a lock is active, the block runs at the system level: you cannot stop it, you cannot uninstall Cold Turkey, and restarting the computer changes nothing. The block runs until the time you set expires.

That is the point: the decision gets made in advance, when you are thinking clearly, and the tool enforces it even when you are not. It is not comfortable. If you lock yourself out of something you actually need, there is no quick fix. The interface is functional rather than polished. But for anyone who has already proven they will bypass softer tools, nothing else on Windows comes close.

Side by side

Which one to use

Start with the weakest tool that will actually hold for you. If a browser extension is enough, use it. If you need cross-platform coverage and generally keep your own rules, Freedom is a reasonable choice.

If you have already bypassed the easier options — and you know you have — Cold Turkey Pro with locked blocks is the only Windows tool built to hold against a motivated user. Pair it with Techlockdown on iPhone to close the device-switching loophole.
