User Agent Parser
Paste a user-agent string and get a quick readable breakdown.
Decode a user-agent string
User-agent strings are dense and cryptic, packing browser, engine, OS, and device into one line. This parser breaks a pasted user-agent into a readable breakdown, so you can quickly tell what a request came from.
It is handy for debugging device-specific issues from logs, checking analytics, and understanding a support report. Paste the user-agent string and get a clear summary of the browser, operating system, and device it describes.
Private and instant
Everything runs locally in your browser using standard web APIs — nothing is uploaded, logged, or stored on any server — so the tool works offline, responds instantly, and keeps whatever you paste in on your own device. That makes it safe to use even for confidential, client, or internal data you would never send to an unknown website.
