What is a User Agent String?

A user agent string is a text string that your web browser sends to websites to identify itself. It contains information about your browser type, version, operating system, and sometimes device type. Websites use this information to deliver content optimized for your specific browser and device.

Components of a User Agent String

Browser Information

The user agent includes your browser name (Chrome, Firefox, Safari, Edge) and its version number, helping websites ensure compatibility.

Operating System

Your OS (Windows, macOS, Linux, iOS, Android) and version are included, allowing sites to serve platform-appropriate content.

Device Type

Mobile devices often include additional identifiers that help websites detect if you're on a smartphone, tablet, or desktop.

Rendering Engine

Information about the rendering engine (Blink, Gecko, WebKit) used by your browser to display web pages.

Common Use Cases
