Find out what web browser you're using, including version, device type, and operating system. Use our free browser detection tool for quick diagnostics.

If you're troubleshooting a website issue, working with customer support, or testing browser compatibility, knowing exactly what browser you're using (and on what device) is essential. The What Is My Web Browser Tool instantly detects and displays your current browser name, version, rendering engine, operating system, and user agent string — all in one place.

No technical knowledge needed — just open the page, and the data appears automatically.

What Does This Tool Detect?

The What Is My Web Browser Tool gathers the following data:

• Browser Name (e.g., Chrome, Safari, Firefox, Edge)
• Browser Version (e.g., Chrome 124.0.6367.62)
• Rendering Engine (e.g., Blink, WebKit, Gecko)
• Operating System (e.g., Windows 11, macOS Ventura, Android 14)
• Device Type (e.g., desktop, mobile, tablet)
• User Agent String (the full string sent by your browser)

All data is collected in real-time from your current browser session.
