User-Agent Parser

The User-Agent Parser extracts and interprets the User-Agent header string sent by web browsers and HTTP clients. This string contains encoded information about the client's browser version, rendering engine (Webkit, Gecko, Trident, etc.), operating system, device type, and CPU architecture. The tool parses this complex string according to industry standards and displays each component in an easy-to-read format.

You can use the parser in two ways: paste any User-Agent string into the input field, or click the auto-detect button to analyze your current browser's User-Agent in real-time. The parser immediately breaks down the string into individual components, showing you the browser name and version, engine type, OS version, device category, and CPU information. All processing happens in your browser without sending data to external servers, ensuring complete privacy.
