    What Is Browser Detection?

    Every time you visit a website, your browser shares details about itself — including its name, version, operating system, and device type. Websites use this to optimize layouts, enable features, and ensure compatibility.

    These same details can also be combined into a "fingerprint" that helps identify your device across websites. This is separate from cookies and works even in incognito mode.

    What This Tool Shows

    • Browser name and version
    • Operating system and platform
    • Device capabilities (memory, CPU cores, touch)
    • Privacy signals (cookies enabled, Do Not Track)

    Why This Matters

    Understanding what your browser reveals helps you troubleshoot website issues and assess your exposure to tracking. For a deeper look at one specific signal, check your user agent string — it's the core identifier your browser sends with every request.

    Privacy-focused browsers like Firefox, Brave, and Tor limit the data shared to reduce fingerprinting.

    Privacy Note

    All the information shown above is available to every website you visit. Combined, these data points can create a unique profile of your device. This tool helps you see what's exposed. We don't store, track, or log any of your data.

    Frequently Asked Questions

    Is this browser detector free to use?

    Yes, our browser and device detector is 100% free and ad-free. We believe privacy diagnostics should be accessible without intrusive tracking or advertisements.

    Can websites detect my browser?

    Yes, they can read your browser type, version, OS, and user agent string.

    Is this information private?

    Not entirely. It's available to any website you visit unless masked.

    Can I fake my browser info?

    Yes, using user-agent switchers or privacy tools, but results may vary.

    Why would I care about browser detection?

    To troubleshoot access issues or understand tracking vectors.

    What Are First-Party Cookies?

    First-party cookies are cookies created by the website you are directly visiting. They help websites remember things like your login session, language preferences, shopping cart contents, and security settings. Most websites rely on first-party cookies for core functionality, so browsers generally allow them by default.

    What Are Third-Party Cookies?

    Third-party cookies are cookies created by a different domain than the website shown in your address bar. They are commonly used by advertising networks, analytics services, embedded videos, social media widgets, and other external content loaded into a page. Third-party cookies have historically been one of the main mechanisms used for cross-site tracking, which is why browsers like Safari, Firefox, and Brave block them by default, while Chrome allows users to control them through privacy settings.

    What Is Do Not Track (DNT)?

    Do Not Track (DNT) is an optional browser setting that sends a request asking websites not to track your activity across the web. However, DNT is voluntary and websites are free to ignore it — most do. Modern privacy protection mainly comes from browser privacy features, blocking third-party cookies, anti-tracking systems, and privacy-focused browser extensions.

    Why Isn't Third-Party Cookie Detection Always Perfect?

    Modern browsers handle third-party cookies differently, and some privacy tools or browser extensions may interfere with testing. In certain cases, browsers may block embedded iframes entirely, partition storage instead of fully blocking cookies, or apply additional anti-tracking protections that affect the result. Because browser privacy systems constantly evolve, this test should be considered a best-effort detection rather than an absolute guarantee.
