About Browser Detection

This tool detects your browser and device information using JavaScript APIs available in your browser. No data is sent to any server -- everything is detected locally on your device. The information displayed includes your browser name and version, operating system, screen properties, hardware capabilities, and privacy settings.

Why Check Your Browser Info?

Knowing your browser details is useful for troubleshooting website compatibility issues, verifying your privacy settings, checking if your browser is up to date, and understanding what information websites can see about your device. Web developers also use this information to debug cross-browser issues.

What Websites Can See

Every time you visit a website, your browser shares information like your User-Agent string, screen resolution, language preferences, timezone, and supported features. This is normal browser behaviour used for rendering pages correctly. However, this combination of data points can create a unique fingerprint, which is why privacy-conscious users consider using VPNs and privacy-focused browsers.

Frequently Asked Questions

How does browser detection work?
Browser detection uses the User-Agent string sent by your browser with every web request. This string contains information about your browser name, version, and operating system. Modern tools also use feature detection and JavaScript APIs for more accurate results.
Why should I know my browser version?
Knowing your browser version helps with troubleshooting website issues, ensuring compatibility with web applications, and verifying you have the latest security updates installed. Outdated browsers may have security vulnerabilities.
What is a User-Agent string?
A User-Agent string is a text identifier sent by your browser to websites. It contains your browser name, version, operating system, and device type. Websites use this information to serve appropriate content and optimize the experience for your device.
