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 (X11; Linux x86_64; rv:153.0) Gecko/20100101 Firefox/153.0.

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.

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.
