This tool shows, at a glance, what your browser knows about your computer or phone: the browser and operating system, screen resolution and pixel ratio, CPU core count, approximate memory, graphics (GPU) renderer, colour depth, touch support and more. It's handy for quick diagnostics, filing bug reports, confirming a display is running at the right resolution, or simply seeing the information any website can read about your device. All locally, with nothing uploaded.
Screen resolution is your display's pixel dimensions, and the device pixel ratio tells you how many physical pixels back each CSS pixel, a value above 1 means a high-DPI "Retina" screen. CPU cores (logical processors) and device memory are reported approximately and rounded by the browser for privacy. The GPU renderer comes from WebGL and names your graphics hardware, which is useful when checking driver or performance issues.
Browsers deliberately coarsen or withhold certain details to limit fingerprinting, the practice of identifying a device from its unique combination of properties. Device memory is rounded to a power of two, CPU cores may be capped, and some browsers mask the exact GPU. So treat these figures as indicative rather than exact, especially on privacy-focused browsers.
When you report a website or app problem, including your browser version, OS, screen resolution and GPU helps developers reproduce it. This page gathers those in one place so you can copy them into a report. Because everything is read client-side, it reflects exactly the environment you're browsing in right now.
All values are read from your browser's own APIs and displayed locally; nothing is sent to a server, logged or stored. Refresh the page any time to re-read the current state.
Through standard browser APIs a site can read your browser and OS, screen size and pixel ratio, language, time zone, logical CPU cores, an approximate memory figure, and the GPU name via WebGL. This tool simply surfaces those same values so you can see them yourself. It can't read personal files, your exact hardware serial numbers, or anything outside the browser.
Browsers intentionally round and cap these values to reduce fingerprinting. Device memory is reported as a rounded power of two, and the logical-core count can be limited. So the numbers are approximate indicators, not a precise hardware readout.
It's how many physical screen pixels correspond to one CSS pixel. A ratio of 1 is a standard display; 2 or 3 indicates a high-DPI "Retina"-style screen where text and images are rendered with extra pixels for sharpness. It's useful for understanding how your screen scales content.
Some browsers mask the detailed WebGL renderer string for privacy, showing a generic value or nothing at all. If it's hidden, it's a deliberate anti-fingerprinting measure in your browser rather than a fault, the GPU is still working normally.
No. Every value is read from your browser locally and shown on the page. Nothing is sent to a server, stored or tracked, and there's no sign-up. It works offline once the page has loaded.
