What Is My Browser
The What Is My Browser tool detects and displays the browser name, version, operating system, and user agent string of the device you're currently using.
What Gets Detected and Why It Matters
- Browser name and version — identifies which browser (Chrome, Firefox, Safari, Edge) and specific version number you're running, which matters for troubleshooting compatibility issues with specific websites or web apps.
- Operating system — detects the underlying OS and version, useful when reporting a bug where the same website behaves differently across platforms.
- User agent string — the raw text string your browser sends to every website, which is how servers identify what browser and device is making a request.
Why This Simple Check Is Genuinely Useful
Many people don't actually know their exact browser version, especially since modern browsers update silently in the background. Knowing the precise version matters when a website reports a compatibility error, when following a tutorial that specifies a minimum required browser version, or when a developer asks "what browser and version are you using?" while troubleshooting an issue you've reported.
A Note on User Agent Accuracy
Some browsers and privacy extensions intentionally mask or randomize parts of the user agent string to reduce fingerprinting, so the detected value may not always perfectly match your browser's true identity — this is an intentional privacy feature, not a detection error.
