Browser Info Tool
View detailed information about your web browser, device, and system capabilities.
Understanding Your Browser Information
Your web browser reveals various details about your system to websites you visit. This browser information tool displays everything websites can detect about your browser, device, and configuration. Understanding this data helps with debugging, privacy awareness, and development testing.
Browser information is used for compatibility checking, analytics, personalization, and sometimes fingerprinting. Modern browsers provide APIs to access hardware capabilities, language preferences, and display characteristics.
Browser and Engine Detection
The browser name and rendering engine determine supported features. Chrome and Edge use Blink, Firefox uses Gecko, Safari uses WebKit. Each engine has different capabilities and sometimes requires specific code paths for compatibility.
Hardware Information
Device Memory and Hardware Concurrency (CPU cores) help websites optimize performance. High-performance devices might receive richer features, while constrained devices get lighter experiences. This enables progressive enhancement.
Display Characteristics
Screen resolution, color depth, and pixel ratio inform responsive design decisions. High DPI displays (pixel ratio greater than 1) need higher resolution images. Touch points indicate touch screen capability for mobile-optimized interfaces.
Privacy Settings
Do Not Track indicates your privacy preference, though many sites ignore it. Cookie settings affect session persistence and tracking. Modern browsers offer enhanced privacy features that limit information exposure.
Using Browser Info for Development
Developers use browser information for feature detection, debugging cross-browser issues, and optimizing performance. Understanding what's available helps build better, more compatible web applications.
