Parse a User Agent String

Every time your web browser makes a request to a website, it sends a HTTP Header called the "User Agent". The User Agent string contains information about your web browser name, operating system, device type and lots of other useful bits of information.

But every browser sends its user agent in a different format, so decoding them can be very tricky.

Use this tool to parse any user agent string you want to understand. We'll show you what the user agent means; whether it's a popular system like Safari on iPad, Chrome on Windows, whether it's a search engine spider bot or security analysing tool.

Why not start by parsing your browser's own user agent.
