User Agent Parser
Paste a browser user-agent string to identify the likely browser family, operating system, device type and rendering engine.
How to Use the User Agent Parser
Paste a browser user-agent string to identify available details about the browser, operating system and device. This is useful for debugging compatibility issues, analytics data and request logs.
Practical Example
A user-agent string from a desktop Chrome browser may reveal Chrome as the browser family, Windows or macOS as the operating system and a desktop-class device.
Factors That Affect the Result
User-agent formats vary by browser, device and operating system, and some browsers intentionally reduce or spoof identifying information. Parsed results should be treated as best-effort hints rather than guaranteed device facts.
