What a user agent is
The user agent is a line of text your browser sends with every request. It names the browser, its version and your operating system, so sites can serve pages that work on your device.
It's written in an old and odd format: almost every browser starts with "Mozilla/5.0", and Chrome, Edge and Opera all mention Safari. That's why tools like this one read the whole string instead of the first word.
Why the version or system can look wrong
Chrome, Edge and other Chromium browsers now shorten the user agent. It shows only the major version (for example 130.0.0.0) and always says Windows 10, even on Windows 11. The full details are in client hints, which this page reads when your browser offers them.
Extensions, developer tools and some privacy browsers can also change the user agent. If this page shows a browser you're not using, one of them is probably active.
How to check your browser version yourself
- Chrome: menu ⋮ > Help > About Google Chrome, or open chrome://version.
- Edge: menu … > Help and feedback > About Microsoft Edge, or open edge://version.
- Firefox: menu ☰ > Help > About Firefox.
- Safari on Mac: Safari > About Safari. On iPhone and iPad, Safari's version follows iOS: Settings > General > About.
