Block distracting websites and allow temporary access when you need it. Block distracting websites with simple rules that stay in your browser. Add a website once and OSBE Site Blocker blocks every page on that domain and its subdomains. Manage your list from a clear dashboard without creating an account. WHAT YOU CAN DO - Add, edit, disable, or remove blocked websites. - Pause all blocking without losing your list. - Allow access to one website for 5, 10, 15, or 30 minutes. Blocking resumes automatically when the timer ends. - Create more-specific exceptions. For example, block google.com while allowing mail.google.com. - Import and export your block list as a JSON file. - Check whether the current tab is blocked from the toolbar popup. - See which rule caused a page to be blocked. PRIVATE BY DESIGN Your block list and settings are stored locally in Chrome. OSBE Site Blocker has no account, analytics, advertising, or remote sync. The optional “Verify official build” action contacts osbe.dev only after you click it. It sends the extension name, version, runtime ID, and a short-lived verification challenge. It does not send your block list, settings, or browsing activity. OSBE Site Blocker is open source.
