SiteWarden
Block distracting sites — only while you're trying to focus.
SiteWarden blocks distracting sites automatically, but only when you actually need to focus. Open a "focus" page like Docs or Notion, and your blocklist activates. Close it, and the web opens back up. No schedules, no permanent blocklists fighting you.
