Tab Guardian

About

Tab Guardian helps you take control of your browser tabs and system memory.

  🔍 MONITOR
  • See all open tabs with real-time idle tracking
  • View JS heap memory and site storage (cache) per tab
  • System memory usage bar with percentage
  • Tabs automatically grouped into "Active" and "Stale" sections

  ⚡ CLEAN UP
  • Close individual tabs or all stale tabs with one click
  • Clear site data (Cache Storage, IndexedDB, localStorage, Service Workers) per tab — no page reload needed
  • Adjustable idle threshold: 15 minutes, 30 minutes, 1 hour, 2 hours, or 4 hours

  🔔 STAY INFORMED
  • Badge shows stale tab count or total count when exceeding 8 tabs
  • Desktop notifications when tabs go stale or you have too many tabs open
  • Checks automatically every 5 minutes

  🎨 DESIGN
  • Clean, modern dark and light theme — automatically matches your system preference
  • Built with DaisyUI and Tailwind CSS
  • Fixed header with scrollable tab list — works great even with 100+ tabs

  🔒 PRIVACY
  • Zero data collection — no analytics, no tracking, no external requests
  • All tab activity data stored locally on your device only
  • Open source — inspect the code yourself
