Privacy & Security
Do Not Track: A browser signal asking websites not to track you. Most sites ignore it, but enabling it shows intent.
Cookies: Small data files websites store in your browser. Required for most logins but also used for tracking.
WebRTC: Used for video calls and real-time communication. Can leak your real IP address even through a VPN.
Local Storage: Allows websites to store data in your browser. Can be used for persistent tracking across sessions.
Ad Blocker: Blocks advertisements and tracking scripts. Improves privacy and page load speed.
Private Browsing: Prevents your browser from saving history and cookies locally, but does not hide your IP address from websites.
JavaScript & Features
Hardware
Your web browser is the software you use to access websites – such as Chrome, Firefox, Safari, or Edge. Each browser has a unique combination of version number, rendering engine, and capabilities that affect how websites look and behave for you. Knowing your browser details is useful for troubleshooting website issues, checking compatibility, and understanding your online privacy exposure.
This tool detects your browser, operating system, screen specifications, network connection, and privacy settings – all without making any external API calls. Every check runs entirely within your browser using standard JavaScript APIs, so no personal data ever leaves your device.
Frequently Asked Questions
What browser am I using?
Your browser name and version are shown in the “Browser” section above. The tool detects this from your browser’s user agent string and other signals. Common browsers include Google Chrome, Mozilla Firefox, Apple Safari, Microsoft Edge, and Opera.
How can I check my browser version?
The version number appears next to your browser name in the results above. You can also check manually: in Chrome, go to Settings then About Chrome. In Firefox, go to Help then About Firefox. In Safari, go to Safari then About Safari. In Edge, go to Settings then About Microsoft Edge. Keeping your browser up to date is important for security.
Is my browser up to date?
An outdated browser can expose you to security vulnerabilities and cause websites to display incorrectly. Most modern browsers update automatically – but it is worth checking. Visit your browser’s “About” page (usually found in the Help or Settings menu) to see if an update is available. If your browser version shown above is significantly behind the latest release, update it as soon as possible.
What is a browser fingerprint?
A browser fingerprint is a collection of technical details about your browser and device – screen resolution, installed plugins, timezone, language, and more – that together create a near-unique identifier. Websites and advertisers can use this fingerprint to track you across the web, even without cookies. The canvas fingerprint hash shown in our results is one component of this. Unlike cookies, fingerprints are difficult to clear or block.
How do I protect my browser privacy?
Several steps can reduce your browser’s privacy exposure: enable Do Not Track in your browser settings, use a reputable ad blocker to stop tracking scripts, disable WebRTC to prevent IP leaks (especially important when using a VPN), use private browsing mode for sensitive activity, and consider a privacy-focused browser like Firefox or Brave. For full IP protection, use a trusted VPN service – you can verify it is working correctly with our VPN leak test.
How this tool works
This tool runs entirely in your browser and our server. We detect your IP address server-side, then perform DNS and WebRTC checks client-side. No account is needed and no personal data is stored beyond anonymous aggregate statistics.
Results are based on real-time checks against your current connection. For the most accurate results, ensure your VPN is fully connected before running the test.
