This tool monitors all network requests made by this page using PerformanceObserver and fetch patching. It captures resource loads, fetch calls, and XHR — like a lightweight local DevTools network tab.

Start monitoring to capture requests.
  • Only requests from this page are captured — no other tabs or apps.
  • Data never leaves your browser. Nothing is sent to any server.
  • This is an educational tool — for full network analysis, use browser DevTools (F12 → Network).
