System Info

This tool reads browser and device properties to show you a snapshot of the environment the page is running in. It detects browser and operating system from the user agent, reports screen size and pixel ratio, enumerates CPU cores and device memory, exposes the timezone and language, and probes WebGL and Canvas support along with the underlying GPU renderer.

1. Open the tool; detection runs automatically and the info banner confirms values are read from your browser. 2. Browse the grid of cards, each showing one property with an icon. 3. To refresh values, reload the page, because all reads happen once on mount. 4. Use the values when debugging compatibility issues, GPU driver problems, or locale-specific rendering.

The cards report: Browser (parsed from UA: Chrome, Safari, Firefox, Edge, or Opera); OS (Windows, macOS, Linux, Android, iOS); Device (Mobile vs Desktop); Screen with devicePixelRatio; Language; CPU cores (navigator.hardwareConcurrency); Memory (navigator.deviceMemory, where supported); Timezone and UTC offset; Connection type and downlink via navigator.connection; WebGL renderer (unmasked via the WEBGL_debug_renderer_info extension); Canvas support; Touch capability; Cookie enabled state; and Do Not Track preference.
