About This Tool
A user-agent string is a line of text every browser sends with each request, identifying the browser, its version, the operating system, and the device type. This tool decodes that dense string into readable fields, since the raw value is a tangle of tokens kept for historical compatibility.
Parsing a user agent is useful for debugging why a site behaves differently across devices, for checking analytics, or for confirming what a script or bot reports itself as. Because the string is self-declared and can be changed, it is a hint about the client rather than proof, which is worth keeping in mind for anything security related.
How to Use It
- Paste a user-agent string, or read your own.
- See the browser, version, operating system, and device parsed out.
- Use the breakdown to debug device-specific behaviour.
