Frequently Asked Questions

FAQs about What Is My User Agent

What is a User-Agent string?

A User-Agent string is sent by your browser with every HTTP request. It identifies your browser, version, operating system, and rendering engine.

Can I use this to test how my site sees different browsers?

This tool shows your current browser's User-Agent. To test specific strings, you can paste them into your browser's DevTools console under navigator.userAgent.

Why does the UA string look so verbose?

For historical compatibility reasons, all modern browsers include tokens from older browsers (like "Mozilla/5.0") in their UA strings.

Is this information private?

Your User-Agent is sent with every HTTP request you make, so it is not secret. This tool simply makes it easy to view and copy.

Is my data safe?

Everything runs in your browser. No data is sent to any server.
