DevHTTP Tracker

About

DevHTTP Tracker is a lightweight developer tool for inspecting the HTTP behavior
of the page you are viewing — without blocking or modifying any traffic.

FEATURES
• Redirect chain — follow every 301/302/307/308 hop from the original URL to the
  final destination, with status codes and reasons.
• Final HTTP status — the final status code and its description (e.g. 404 Not
  Found, 403 Forbidden) shown front and center.
• Headers — response and request headers in a clean, switchable tabbed view.
• Timing — waiting (TTFB), content download, and total time for the navigation.
• One-click copy — copy the full report as JSON, or copy the final URL.
• Automatic dark / light theme that follows your system.

PRIVACY-FIRST BY DESIGN
• Read-only: it never blocks, modifies, or redirects requests.
• No backend, no tracking, no ads. Nothing leaves your browser.
• Data lives only in memory for the current session and is discarded when the
  tab is closed or the browser exits.

Note: after installing, reload a page to start tracking it.
