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
Filter by user agent and the matching requests appear right below. Showing requests whose user agent contains Mozilla/5.0 (compatible; YandexBot/3.0; +http://yandex.com/bots).

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 Mozilla/5.0 (compatible; YandexBot/3.0; +http://yandex.com/bots).

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.
