A quiet site blocker for Chrome. Your list stays on your computer. Set a weekly focus schedule and close the loopholes other blockers leave open.
Chrome Web Store listing coming soon. Free plan blocks up to 10 sites.
Blocking works through Chrome's own rule engine. Fast, local and private.
Install and start blocking. There is no sign-up, no email, no cloud sync. Your list is stored in Chrome on this computer.
Strict mode blocks m. and old. subdomains, Google image and search redirect links that point to a blocked site, and the site inside embedded frames.
Block from 9 to 12:30 and 13:30 to 18 on weekdays, late nights on Saturday, nothing on Sunday. Each day gets its own hours.
Need a minute? Type a sentence you wrote yourself, take a short break, and stop when the daily limit is used up.
Block any address that contains a word, like shorts or reels, without blocking the whole site.
No tricks to stop you from removing the extension and no remote code. It is a tool for your own focus, not spyware.
The free plan is a complete blocker. Pro adds the tools for harder habits.

No. There is no account and no sign-up. When you buy Pro you receive a license key by email from Dodo Payments and paste it into the extension.
None. Your block list, schedule and settings stay in Chrome storage on your computer. The extension only talks to the internet to check your license key with Dodo Payments, and that request contains the key and nothing else.
Chrome shows this for any extension that redirects a blocked page to its own block screen. The extension never reads page content. It uses Chrome's declarativeNetRequest rules, which Chrome applies without giving the extension your browsing history.
No, and we will not pretend otherwise. Anyone can remove or disable an extension from chrome://extensions. Site Blocker adds friction to impulsive unblocking, which is what most people need.
Only if you allow it. Open chrome://extensions, choose Details on Site Blocker and turn on Allow in Incognito.
Rules apply to the next page load. Reload an open tab, or it will be blocked the next time you navigate.
No. Pro is a one-time payment and works for the life of the product on your browsers, within the activation limit of your key.
Yes. Ask within 14 days of purchase and you get a full refund. See the refund policy.
