User-Agent Parser

NEW

Parse a User-Agent string into browser, version, OS, and device type.

Frequently asked questions

Where does the default text come from?

It's pre-filled with your own browser's User-Agent string on load — you can clear it and paste any other User-Agent to inspect instead.

Why did it get the browser or OS wrong?

User-Agent strings are inconsistent across vendors and easily spoofed by design (a browser can claim to be anything), so this is a best-effort pattern match, not a guaranteed-accurate one.

Does this run on a server?

No — parsing happens entirely in your browser with regular expressions. The string you paste is never sent anywhere.
