Device Info detects and displays comprehensive information about your current browser and device using JavaScript APIs — screen resolution, viewport dimensions, device pixel ratio, color depth, available memory, CPU core count, connection type, and browser capabilities. It reads navigator, screen, and performance APIs to report touch support, WebGL renderer, installed fonts, language settings, and media query matches for prefers-color-scheme and prefers-reduced-motion without requiring any server-side detection.
Frontend developers debugging cross-device rendering issues, QA engineers documenting test environments, and support teams collecting diagnostic information from users. The tool runs entirely in your browser — your data never leaves your device.
