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

Find slow tabs instantly. Monitor CPU, RAM, and network usage per tab to speed up Chrome and reduce memory usage.

🚀 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. ────────────────────────── PERMISSIONS EXPLAINED • Tabs — list and switch to tabs from the popup • Storage — save your appearance and threshold settings • Web Request — measure per-tab network bandwidth • System CPU & Memory — display your hardware specs in System Info • Debugger (optional, Accurate Mode only) — read precise CPU/RAM for the active tab
