Frequently Asked Questions
What is a User-Agent string?
A User-Agent string is a line of text that your web browser sends to every website you visit. It contains detailed information about your browser type, version, and operating system.
Why do IT support teams ask "What is my browser"?
Tech support teams need to know your exact browser and version to troubleshoot website rendering issues, as different browsers (Chrome, Safari, Firefox) interpret code slightly differently.
Does this tool detect mobile browsers?
Yes, this tool works on smartphones and tablets, accurately detecting iOS Safari, Android Chrome, and other mobile browsers.
How does the tool know my screen resolution?
The tool uses simple client-side JavaScript to measure the inner width and height of your active browser window, as well as the total resolution of your physical monitor.
Is my browser information logged or saved?
