Browser Info
Discover detailed information about your browser and system: name, version, OS, screen resolution, language, time zone and more.
Full User Agent
What is this information used for?
On every HTTP request, the browser sends along a string called the User Agent that identifies the client software. Servers lean on that detail to tailor their responses to whichever browser and device is on the other end.
System information, in turn, pays off in bug reports, compatibility checks and technical support. Whenever you report a problem, attach the User Agent so the developer knows precisely which environment to reproduce.
What your browser hands over to sites
Every site you open can read a pile of information about your browser and device, and we hardly ever notice how much that is. This tool lays the data out in the open: browser name and version, operating system, screen resolution, and so on.
Handy when you need to explain a problem to tech support, check whether the browser is up to date, test how a site detects your environment, or just grasp the "digital fingerprint" you leave while browsing. Everything you see here is exactly what any site sees too.
The detection runs entirely in the browser and only reads what it already exposes, storing and sending nothing anywhere. It's a quick way to view your environment through a site's eyes.
