User Agent Parser FAQ

What does a user agent parser do?

A user agent parser reads the user agent string sent by a browser, app, crawler or device and tries to identify the browser, version, operating system, device type and rendering engine.

Where do I find a user agent string?

User agents often appear in server logs, analytics reports, debugging tools, browser support tickets and HTTP request headers. You can also click the “Use My UA” button to see the one your current browser reports.

Can a user agent identify the exact device?

Sometimes. iPhone, iPad, common Android models and many bots are easy to detect. Some browsers hide or simplify device details, so the exact model is not always available.

Why does Windows 11 sometimes show as Windows 10?

Many Windows 11 browsers still use the same Windows NT 10.0 token. A normal user agent string usually cannot reliably separate Windows 10 from Windows 11.

Does this parser store my user agent string?

No. The parsing happens locally in your browser. The pasted user agent string is not uploaded by this tool.

Can user agents be spoofed?

Yes. Browsers, crawlers and automated clients can change their user agent text. Use parser results as clues for debugging, not as verified proof of identity.
