Frequently Asked Questions

What is a User Agent string?

A User Agent (UA) is a string your browser sends to every website you visit, identifying your browser type, version, and operating system.

Why do I need my User Agent?

Developers use UA strings to test browser compatibility, report bugs, and configure server-side analytics.

Can websites use my User Agent to track me?

Yes — User Agent strings are one of many signals used in browser fingerprinting. Using a VPN or privacy browser can help reduce tracking.

How do I change my User Agent?

Browser developer tools allow you to override your User Agent for testing. Chrome DevTools > Network conditions > User Agent.
