About What is my Browser

Confused about which browser you're using or need to confirm version details for support tickets, compatibility testing, or debugging? Our What is My Browser tool instantly analyzes your user agent string to reveal everything about your browsing environment—no clicks, no input required.

Just visit the page and see real-time results: browser name (Chrome, Firefox, Safari, Edge, etc.), exact version, rendering engine, operating system (Windows, macOS, Android, iOS), device type (desktop, tablet, mobile), and even screen resolution. It’s ideal for users reporting issues, developers testing responsive designs, or IT teams verifying corporate browser policies.

Key details displayed:

• Browser & Version: e.g., Chrome 129.0.0.0.
• Operating System: Full platform with build info.
• Device Info: Mobile, tablet, or desktop classification.
• Screen & Viewport: Current resolution and pixel density.
• User Agent String: Raw header for advanced use.

Web designers use it to ensure cross-browser compatibility, support teams to guide users accurately, and privacy-conscious visitors to understand what sites see. Lightweight, accurate, and 100% client-side—nothing is sent to servers. Check anytime, completely free, no login or tracking!
