📖 Deep Dive: User Agent Parser

What is a User-Agent

A UA is a self-describing text string a browser sends when visiting a site, containing info about the browser, engine, and operating system.

Parsing logic

This tool uses a set of regular expressions to match common signatures: Chrome/Edge/Firefox/Safari, Windows/macOS/iOS/Android/Linux, Blink/WebKit/Gecko engines, and iPhone/iPad/Android devices.

Limits and notes

  • A UA can be faked and must not be used as a security basis.
  • Browsers are gradually reducing UA info (UA reduction), so less will be parseable in future.
  • Results are for reference only.
