About What is my Browser
Our What Is My Browser tool instantly detects and displays your current browser name, version, operating system, device type, screen resolution, and user agent string. This information is essential for web developers troubleshooting browser-specific issues and testers documenting their testing environment.

Who Uses This Tool
QA testers use it to record the exact browser and OS combination a bug occurred in before filing a report, so developers can reproduce the issue on the same setup. Web developers use it while cross-browser testing a new layout, quickly confirming which rendering engine and version is running without opening developer tools. Support teams use it to ask customers to visit the page and paste back their browser and device details instead of trying to talk a non-technical user through finding that information manually. IT administrators use it to verify which browser versions are actually in use across an office before deciding which features or polyfills are safe to drop. Developers building responsive layouts also use it to quickly confirm the viewport and screen resolution being reported before debugging a display issue.
Frequently asked questions
Why do I need to know my browser and OS details?
It's the fastest way to give accurate information to tech support, troubleshoot a compatibility issue, or confirm your browser is up to date for security purposes.
Does this tool track or store my browser information?
No - your browser details are read and displayed directly in the page; nothing is logged or sent to a server.
What is a user agent string?
It's a text identifier your browser sends to every website, describing the browser, version, and operating system - websites use it to serve compatible content, though it can be spoofed and isn't fully reliable for strict detection.
