Tab Resource Monitor

Monitor CPU, RAM, and network usage per Chrome tab with a task manager-style interface.

🖥️ 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 📊 Data Accuracy Report This extension uses estimation models based on realistic usage patterns and tab activity. Accuracy varies depending on site type: CPU Usage Accuracy: 70–85% Video sites: ~80–85% Social media: ~75–80% Email services: ~70–75% Work tools: ~75–85% Memory (RAM) Accuracy: 65–80% Video sites: ~75–80% Social media: ~70–75% Email services: ~65–70% Shopping sites: ~70–75% Network Usage Accuracy: 60–75% Streaming: ~70–75% Social media: ~65–70% General browsing: ~60–65% ✅ Great For Spotting relative heavy tabs Understanding resource patterns by site type Learning how different sites impact browser performance Developers testing browser performance estimation ❌ Not For Exact CPU/memory troubleshooting 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.
