Tab Manager & Resource Monitor – CPU, RAM Usage per Tab

🚀 Stop guessing why your browser is slow.

Tab Resource Monitor gives you a live task manager right in your toolbar showing CPU, RAM, and network usage for every open tab, color-coded by impact.

Spot the tab eating your memory. Close it. Done.

✅ Real-time CPU, RAM & network stats per tab
✅ Color-coded alerts — see heavy tabs at a glance
✅ One-click close or refresh from the popup
✅ Total usage summary across all tabs
✅ System Info: CPU model, cores, RAM, GPU
✅ Pinnable on-page widget — monitor without opening the popup
✅ Auto-refreshing every 1–10 seconds (your choice)
✅ Dark mode & compact view
✅ 100% local — no data ever leaves your browser

Built for developers, power users, and anyone running 20+ tabs who wants their browser back.

HOW IT WORKS
CPU & RAM figures are estimated from real page signals — Long Tasks, FPS, event-loop lag, DOM complexity, and resource size. Network (MB/s) is measured from request metadata. For the active tab, Accurate Mode uses the DevTools protocol for precise readings.

All processing is on-device. No telemetry. No tracking.
