What Is My Browser

Support asked which browser you are on, a website behaves strangely, or a bug report form wants your exact version — this page answers instantly. The moment it loads you see your browser name and version, your operating system, the rendering engine and the full user agent string, ready to copy with one click.

Detection is done properly: where the browser offers the modern navigator.userAgentData API the tool reads the official brand and platform information from it, and elsewhere it falls back to a compact parser of the user agent string that recognizes Chrome, Edge, Firefox, Safari and Opera on Windows, macOS, Linux, Android and iOS. When something genuinely cannot be determined — and modern browsers deliberately hide some details, such as the exact macOS version or whether Windows 10 or 11 is running — the tool says so honestly instead of inventing precision.

Beyond the headline answer you get the practical context web developers and support engineers usually need next: the browser interface language, whether cookies are enabled, the current viewport size in pixels (updated live as you resize), the device pixel ratio of your display and whether the device reports touch support.

Unlike many similar pages this one does no fingerprinting and no IP-based lookups: there is no geolocation panel, no tracking script and no request to any server. Your own browser reads out what it already knows about itself, locally, and nothing you see on this page ever leaves your device.
