About this tool
A User-Agent is the text a browser sends to identify itself to websites. Paste one into the box and the tool breaks it down into the browser and version, the operating system, a device guess (desktop, mobile or tablet) and whether it looks like a bot or crawler. Parsing is a set of simple pattern checks that runs entirely in your browser. It recognizes Edge, Opera, Firefox, Chrome and Safari, and a handful of operating systems. For your own browser's details, the What Is My Browser tool shows your live User-Agent and more. Unknown strings show as Unknown.
How to use it
- Paste a User-Agent string into the box.
- Read the browser, OS, device and bot lines that appear.
- Replace the text to parse another string.
- To get your own string, open What Is My Browser and copy it from there.
Example
Input
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/120.0.0.0 Safari/537.36
Result
Browser: Chrome 120.0.0.0 OS: Windows 10/11 Device: Desktop Bot/crawler: No
Common problems
- Windows 11 is shown as Windows 10/11
- Browsers report Windows 11 as NT 10.0, so the two cannot be told apart from the string.
