User Agent Parser
Detect browser, OS, and device type from any User Agent string — nothing is uploaded.
What is a User Agent?
A User Agent (UA) string is a short text your browser sends with every HTTP request. It tells servers which browser, operating system, and device you're using — so sites can serve compatible content.
This tool parses the UA entirely in your browser. No data is sent to any server.
FAQ
Is my User Agent sent anywhere? No — parsing happens entirely in your browser. Your UA string never leaves your device.
Why does my UA say Chrome even on Edge? Modern Edge is built on Chromium and includes a Chrome token for compatibility. Look for the Edg/ token to confirm it's Edge.
Can I use this to test server-side UA detection? Yes — paste any UA string from logs or device emulators and see the parsed result instantly.
