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.
