How it works
STEP 1
Paste or auto-fill
Drop in any User-Agent string, or press "Use my browser" to fill your own. It is parsed right here — nothing leaves your device.
STEP 2
Read the breakdown
Hand-rolled rules detect the browser and version, rendering engine, operating system and version, device type, and known crawler bots.
STEP 3
Copy the result
Copy the full breakdown as clean JSON with one click — handy for tests, logs or analytics.
