ua-tracer

what does a user agent actually fetch, follow & run?

All recent homepage requests, newest first. This page does not mint a new trace (unlike /), so you can browse the log without adding noise.

Recent homepage requests

Unsolicited / well-known requests

Paths a user agent fetched on its own that ua-tracer never links to: robots.txt, sitemap.xml, /.well-known/*, llms.txt, the root favicon, and similar. Reveals what an agent probes on its own initiative.

By path

Each unsolicited path with its request count and how many distinct user agents hit it. Click a path to see the individual requests; click a user agent below to reverse-look-up everything that UA did.

No unsolicited paths fetched yet.

Requests (0 shown)

The Related trace column links a probe to a homepage trace from the same user agent and IP within 30 minutes (the same crawler that fetched a well-known file usually also loaded /). The offset shows how long before/after the probe that trace was minted.

No unsolicited probe requests match the current filter.
