What's My User Agent?
Instantly see the user-agent string your browser sends with every request, then get a plain-English breakdown of what it reveals — your browser and version, rendering engine, operating system, and device type. Where supported (Chromium browsers), it also reads User-Agent Client Hints for more precise, spoof-resistant details like platform version and CPU architecture, plus session info like screen size, time zone, and language. Everything is read locally in your browser and nothing is sent to a server.
Reading your user agent…
How to use
- Your user-agent string is detected and shown automatically.
- Read the parsed browser, engine, OS, and device breakdown.
