User-Agent Parser

User-Agent string parser

Log files still contain User-Agent strings even as Client Hints grow. Parsing a UA into browser, OS, engine and device helps you reproduce a bug from a support ticket.

Paste any UA or use this browser’s. The parser is heuristic: it looks for Chrome, Firefox, Safari, Edge, Android and iOS tokens. It is not a full ua-parser database.

Do not use UA sniffing as your only feature switch. Prefer feature detection.
