## Parse User-Agent String

## What is a User-Agent String?

A User-Agent (UA) string is a text header that browsers and bots send with every HTTP request to identify themselves. It reveals the browser name, version, operating system, device model, and more. Our parser uses the industry-standard ua-parser-js library to extract structured information from any UA string.
