User Agent Information

What is a User Agent?

A user agent string is a text string sent by web browsers and other applications to identify themselves to web servers. It typically contains information about the browser, operating system, and device.

Common Use Cases:

  • • Web analytics and tracking
  • • Browser compatibility detection
  • • Mobile vs desktop detection
  • • Security analysis
  • • Content optimization

Privacy Considerations

User agent strings can be used for device fingerprinting and tracking. Modern browsers are working to reduce the amount of identifying information in user agents.

Browser Trends:

  • • User agent reduction initiatives
  • • Client hints as alternatives
  • • Privacy-focused changes
  • • Standardization efforts
