User-Agent Parser

v1.0.1

Parse User-Agent strings to identify browser, OS, device type, and engine.

Parses User-Agent header strings into structured components — browser name, version, rendering engine, OS, device type, and bot detection — and lets you test how your server-side UA detection logic handles a given string.

How to use
  • →Paste a User-Agent string into the input or click "Use current browser" to parse your own UA.
  • →Review the parsed fields: browser, version, engine, OS family, device type, and whether it is a bot.
  • →Use the batch mode to test multiple UA strings at once — useful for reviewing analytics log data.
  • →Copy the structured JSON output to use the parsed data in your server-side analytics or feature-flagging code.
