See your browser, operating system, screen resolution, language and other details your device reveals to every website you visit.
Every time your browser opens a page, it sends a string called the user agent that names itself, its version and the operating system underneath. This tool parses that string and adds what JavaScript can see — screen resolution, viewport size, color depth, language, cookie support and touch capability — into a single table.
The information here is not secret: every website you visit already receives it. Seeing it in one place is useful when filing a bug report, when a support agent asks what browser you are using, or when you want to know what a fingerprinting script can see about your device without asking.
Nothing is stored. The page reads your browser headers and the JavaScript APIs and renders them on screen — the result stays on your device and is never uploaded.
No. The information is read from your browser headers and JavaScript APIs and rendered locally. Nothing is uploaded or logged.

Because the viewport is the area inside the browser window, minus the address bar, tabs and any operating system elements.
