Browser Info Detector
See what any website can read about your browser and device the moment you visit: user agent, screen, language, time zone, hardware and privacy settings.
What this shows
Everything on this page comes from standard browser APIs that any site can call without asking permission. Developers use them to serve the right layout, language and image size. The same details can also be combined into a fingerprint, which is why it is useful to see them laid out in one place.
Values marked "Not available" are simply not exposed by your browser. Chrome and Edge report more hardware detail than Firefox and Safari, which deliberately hide some of it. Resize the window and press Refresh to watch the viewport change; it is the number responsive CSS actually reacts to.
For decoding a user agent in more detail, paste it into the Regex Tester, or check your own passwords with the Password Strength Checker.
Frequently asked
Is any of this sent to Curious Assistant?
No. The page reads these values from your own browser and shows them on screen. Nothing is uploaded or stored.
Why does the page know so much about my device?
Browsers expose a lot to every site so pages can adapt to your screen, language and capabilities. Trackers can combine many small details, such as screen size, fonts and graphics card, into a fingerprint that identifies you without cookies.
Why can't it show my IP address?
Your public IP address is visible only to servers you connect to, not to the browser itself. Showing it would need a request to an outside service, and this tool makes none.
How can I expose less?
Browsers such as Firefox and Brave offer fingerprinting protection, and a privacy extension can reduce what sites read. Using a very common window size and keeping your browser up to date also helps you blend in.
