A browser detector reads the User-Agent string sent by your browser and parses it to identify the browser name (Chrome, Firefox, Safari, Edge), version number, and operating system.

Your browser is detected from the User-Agent string automatically sent with every HTTP request. It reveals the browser name, version, and operating system without any input from you.

Key Features

• Detects browser name and exact version number.
• Identifies operating system and version.
• Shows the raw User-Agent string.
• Detects mobile, tablet, or desktop device type.
• No installation or permission required.

How to Use the Tool

1. Simply open the page — your browser is detected automatically.
2. Browser name, version, OS, and user agent are displayed instantly.
3. Share or copy the user agent string for support tickets.

Core Benefits

• Know if your browser is outdated and needs updating.
• Share your browser info with IT support when reporting a web issue.
• Verify browser compatibility before using web APIs.

Common Use Cases

• A developer testing which browser a user is on to reproduce a reported bug.
• Checking if a corporate or school computer runs an outdated browser.
• Providing browser details in a support ticket or form.
• Testing browser detection logic for a web application.

Pro Tips

• Chrome on iOS reports as Safari in the user agent — Apple requires all iOS browsers to use the WebKit engine.
• Brave browser reports itself as Chrome in the user agent to avoid fingerprinting.
• Always update your browser — older browsers miss security patches and web feature support.
