  description

  Block distracting websites with a lightweight, free, local-first focus tool.
  
  Focus Site Blocker helps you create a calmer browsing environment by blocking the websites you choose. Add distracting domains to your block list, and the extension will automatically catch matching pages before they pull you away from your work.
  
  Use the popup to block or unblock the current site quickly, or open the options page to manage your full block list. You can also set an optional redirect URL so blocked visits send you somewhere more intentional, such as a task board, notes page, or another focus-friendly destination.
  
  Features:
  - Block distracting websites by domain.
  - Add or remove blocked sites from the popup or options page.
  - Automatically save changes as you edit your block list.
  - Optionally redirect blocked visits to a URL you choose.
  - Use a simple, lightweight extension with no account required.
  - Built as an open-source Manifest V3 Chrome extension.
  
  Open source:
  Source code is available on GitHub:
  https://github.com/Interpretable-Technologies/focus-extension
  
  Privacy:
  Focus Site Blocker is designed to work locally in your browser. Your blocked domains and optional redirect URL are stored on your device with Chrome extension storage. The extension reads tab URLs locally only to compare the current site hostname against your block list and redirect blocked pages.
  
  Focus Site Blocker does not include analytics, advertising trackers, remote scripts, account sign-in, or data sharing with the developer or third parties.
  
  Support:
  Focus Site Blocker is free to use. If you want to support development, you can buy me a coffee:
