What Is a User Agent?

A user agent is a string of text that your web browser or device sends to websites when you visit them. It provides information about your browser, operating system, device type, and other details that help websites deliver content tailored to your specific setup.

  • Browser Compatibility: Developers use user agents to ensure that their website works correctly on different browsers and operating systems.
  • Analytics and Statistics: User agents provide insights into the types of devices and browsers visitors use, helping website owners make informed decisions.
  • Troubleshooting: Knowing your user agent can be helpful when diagnosing issues with a website or application.
