What Is My Browser

This page reads what your browser reports about itself and lists it in plain words: the browser and its exact version, the rendering engine, your operating system (including whether Windows is 10 or 11 when the browser says so), device type, screen and window size, languages, time zone, cookie and JavaScript status, privacy signals and the graphics card name. It is the information support desks usually ask for, gathered in one copyable list.

How to use this tool

1. Open the page — the results appear straight away.
2. Untick the graphics card option if you prefer not to show it.
3. Copy the values (or the whole user agent string) into your support ticket or bug report.
4. To decode a user agent from a log file, use the user agent parser instead.

Formula

Browser and OS come from User-Agent Client Hints (navigator.userAgentData) when available, otherwise from the user-agent string.

Chromium browsers expose Client Hints with the real brand (Chrome, Edge, Opera, Brave…), the full version and the platform version: a Windows platform version of 13 or higher means Windows 11. Firefox and Safari do not, so for them the page falls back to the user-agent string, whose Windows and macOS versions have been frozen for privacy.

Example

On a Windows 11 PC with Chrome, Client Hints report the brand "Google Chrome" with a full version such as 130.0.6723.92 and platform version 15.0.0. The page shows Chrome 130, engine Blink, OS Windows 11 (15 ≥ 13), plus details such as a 1920 × 1080 screen at device pixel ratio 1.25. The same PC in Firefox shows "Windows 10 or 11", because Firefox sends only "Windows NT 10.0".
