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.

By user agent
Running counts across the last 200 homepage requests (95 distinct agents). Click one to set the filter above.
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.
Filtered to user agent curl/8.7.1.

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.

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.
