🖥️ Tab Resource Monitor
Your Chrome Task Manager — with smart estimates.
Keep your browser running smoothly with real-time, site-aware estimates of CPU, RAM, and network usage for every tab. Tab Resource Monitor helps you spot heavy tabs, understand performance patterns, and take quick action — all from a simple, always-available popup.
⚠️ Note: Chrome extensions don’t have direct access to system CPU/RAM/network data. This extension uses realistic estimation models based on site type, activity, and behavior patterns.
✨ Key Features
Task manager–style view with estimated CPU, memory, and network usage per tab
Alerts for heavy tabs when resources exceed expected ranges
Auto-refreshing stats with smooth live updates
Sortable, color-coded table for quick insights
Lightweight design with dark mode support
Privacy-first: all estimates are generated locally, no data leaves your browser

System-level performance optimization
Precise bandwidth measurement
🔮 Future Improvements
To improve accuracy beyond 90%, Chrome would need to expand API access (Process, WebRequest, Performance Observer). Until then, estimates are designed to be realistic, consistent, and useful for everyday awareness.
🛡 Privacy First: All data is generated and stays in your browser. Nothing is sent anywhere.
