Detect browser, operating system, and device from user agent strings
What is a User Agent? A user agent string identifies your browser, operating system, and device to websites. Parse any user agent to extract detailed information for web development.
A user agent string is a text identifier that browsers send to websites. It contains information about your browser type, version, operating system, and device to help websites optimize content and provide the best experience.
Developers parse user agents to detect browsers, customize experiences for different devices, track analytics, debug compatibility issues, serve optimized content, and provide device-specific features.
User agent parsing is generally very accurate but not 100% foolproof. User agents can be modified or spoofed by users, and new browsers may not be immediately recognized. It's best used with feature detection methods.
