πŸ–₯️ Tab Resource Monitor β€” Your Smart Browser Task Manager

Keep your browser fast and efficient with real-time, site-aware estimates of CPU, memory, and network usage for every tab. Quickly spot heavy pages, understand performance patterns, and take actionβ€”all from a clean, always-available popup.

⚑ Key Features
Task Manager–Style View – CPU, RAM, and Network usage per tab
Color-Coded Alerts – Instantly see problem tabs
Sortable Columns & Smooth Auto-Refresh – Stay up to date at a glance
Total Usage Summary – Track overall browser resource load
System Info (Optional) – CPU model, cores, memory, GPU
Pin-able On-Page Widget – Keep insights visible where you need them
Dark Mode & Compact View – Comfortable in any setup

πŸ” How It Works
CPU & RAM – Estimated from page performance signals (e.g., Long Tasks, FPS, event-loop lag, DOM/resource counts). Browser does not expose true per-tab CPU/RAM.
Network (MB/s) – Approximated from request/response metadata in short windows.
System Info – Uses system APIs for accurate hardware details.
βœ… All processing happens locally β€” no data ever leaves your browser.

πŸ”’ Permissions Explained
Tabs – List and switch between open tabs
Storage – Save your settings (appearance, thresholds, refresh interval)
Web Request – Estimate bandwidth usage (MB/s)
System CPU & Memory – Display accurate hardware info
Host Permissions – Enable per-site estimators and the on-page widget

πŸ›‘οΈ Privacy First

Your browsing data never leaves your device.

As someone with multiple browsers open at once, it's difficult to find which is taking up the most power. This has for sure helped!

Powerful and lightweight. The per-tab resource view keeps Chrome under control.
