Device & Browser Information

This tool shows the information your browser already exposes to any web page: user agent, languages, viewport and screen size, pixel ratio, orientation, touch support, processor count and, where supported, memory, connection type and low-entropy User-Agent Client Hints. It is a support and debugging aid, not a fingerprinting tool: it does not draw canvas or audio tests, create an identifier, request permissions, or contact a server.

Open the page on the device you want to check. Values appear after the page loads and the viewport, orientation and online status update as they change. Select Copy diagnostics to paste a concise JSON summary into a ticket or chat, or download it as a file. Use Refresh after moving the window to another display.

Browsers expose different fields. Safari and Firefox do not provide User-Agent Client Hints, device memory or connection type, and some browsers round or freeze values such as the platform or processor count. Unavailable fields are shown as Not available and left out of the copied JSON instead of being guessed. Nothing is saved, and no IP address is shown because the tool makes no network request.
