HTTP DIAGNOSTIC TOOL

Trace a redirect chain

Paste a URL from your browser bar, a link, or a chat message. The tool prepends https:// if no scheme is given.

Platform limitation: This tool runs inside Cloudflare Workers. Servers that are themselves behind Cloudflare may return "unreachable" even though they work from a regular browser. This is a platform constraint, not a bug. Try a host that is not Cloudflare-fronted (e.g., httpbin.org, wikipedia.org).

BULK TRACE

Trace multiple URLs

Upload a CSV file (one URL per row, first column). Traces each URL one by one and shows aggregate results.
