Request Monitor
Real-time API & Network Request Viewer
Monitor XHR and fetch requests for the current tab in real time. Method and status color coding, duration, size — without opening DevTools.
// screenshots
// overview
Request Monitor captures every network request made by the current browser tab and shows them in a live-updating popup. It uses Chrome's webRequest API to record request method, URL, status code, type (XHR/fetch/script/etc.), response duration, and content-length. The popup refreshes every second while open and keeps the most recent 100 requests per tab. Method colors (GET green, POST blue, PUT amber, DELETE red) and status colors (2xx green, 3xx blue, 4xx/5xx red) let you scan for problems instantly. Use the URL search filter or the All/XHR/Fetch buttons to focus on the traffic that matters. Click any row to expand it and copy the full URL for use in Postman, curl, or other tools.

// faq
Is Request Monitor free?
Yes, completely free with no Pro plan.
Does it capture requests that happened before I opened the popup?
Yes. Request Monitor records requests in the background from the moment a tab loads. When you open the popup, you see all captured requests (up to 100) since the last navigation.
Will it slow down my browser?
No. The webRequest listener adds negligible overhead — it only stores the URL, method, status, and timing metadata, not the response body.
Does it capture POST body or response data?
No. Request Monitor only captures what the webRequest API provides: URL, method, status code, headers for content-length, and timing. Response bodies are never read.
Does it work on every website?
Yes. It captures requests from any tab on any URL.
