About Browser Information
Every time you visit a website, your browser sends a significant amount of information about your device, operating system, network, and preferences.
This tool simply reads the properties available via the window and navigator APIs in JavaScript to show you exactly what any website can instantly know about you without asking for permission. This data is often used for analytics, feature detection, or "browser fingerprinting."
