What this tool does not do / Limits

This parses common user-agent patterns only. It cannot verify that the string is genuine, and unusual, custom or spoofed strings may be reported as Unknown.

Frequently asked questions

Does this identify my own browser automatically?

No. It parses only the string you paste, so you can check any string.

Why might a result say Unknown?

Some strings use patterns this parser does not recognise, or the browser field is missing.
