Reads what your browser reports about this device — browser and platform (including User-Agent Client Hints), languages, screen and viewport, WebGL renderer and WebGPU, network hints (Chromium only), colour-scheme/motion/contrast/pointer preferences, cores, memory, touch points, storage quota and API support — and formats it as a report or JSON. Everything is read on this page and nothing is sent anywhere; the WebGL probe can be skipped.
