User-Agent Parser
Decode a User-Agent string.
Runs entirely in your browser — nothing you enter is uploaded, logged, or tracked.
A User-Agent string packs the browser, rendering engine, operating system and sometimes the device into one cryptic line. Paste any User-Agent (or use your own, shown by default) to break it down into readable parts. It is parsed entirely in your browser — and yes, this page can see your UA, but it never sends it anywhere.
Frequently asked questions
How accurate is the parsing?
User-Agent strings are notoriously messy and often spoofed, so treat the result as a best-effort interpretation of common patterns rather than ground truth.
What’s my own User-Agent?
It is pre-filled by default so you can see exactly what your browser advertises to every site you visit.
Is anything uploaded?
No — parsing happens entirely in your browser.
