User agent parser

Your own user agent is loaded below — replace it with any string from your logs to see how it breaks down.

Paste a user agent string above.

A user agent is a claim, not a fact

Any client can send any string, so treat the parsed result as a weak hint rather than evidence. The useful signal is inconsistency: a mobile user agent arriving from a datacenter range, a decade-old browser version on a fresh TLS stack, or a headless marker paired with a residential proxy. Combine it with network-level intelligence — who owns the address, whether it is a hosting or proxy range — before you make a decision.
