About User-Agent Parser & Device Inspector

A User-Agent parser reads the User-Agent HTTP header string to extract the client's browser name, engine version, operating system, and hardware architecture. The Device Inspector also reports client-side viewport dimensions, device pixel ratio, color gamut, and hardware concurrency.

Zero-Upload Privacy Guarantee

Querying browser capabilities (`window.screen`, `navigator.language`, `window.devicePixelRatio`) directly in client JavaScript provides exact, real-time client diagnostics.
