About What Is My Browser
Our browser detection tool reveals the technical details about your web browser and device that are visible to every website you visit. See your browser name and exact version, the operating system and its version, whether you are on a desktop or mobile device, screen resolution and colour depth, browser language settings, cookie and JavaScript status, your time zone, and whether you have an ad blocker active. Understanding this information helps you troubleshoot compatibility issues and understand web privacy.

What is a user agent string?
