What Is My Browser?

This tool automatically detects your browser name, version, operating system, and device type using the information your browser shares with websites (the user agent string). Just visit this page and the results appear instantly.

Different browsers support different web features, have varying levels of security, and perform differently. Knowing your browser and version helps when troubleshooting website issues or checking if you need to update.

A user agent string is a text identifier your browser sends to every website you visit. It contains your browser name, version, operating system, and sometimes device info. Websites use it to serve compatible content.

Chrome is built on the open-source Chromium project but adds Google-specific features like sync, automatic updates, and some proprietary codecs. Many other browsers (Edge, Brave, Opera) are also based on Chromium.

Most modern browsers update automatically. You can manually check by going to your browser's settings or about page. Keeping your browser updated is important for security patches and new feature support.
