Pro Tips
- •This shows only what your browser voluntarily reports through standard web APIs - it can't reveal your actual IP address, precise location, or hardware serial numbers
- •Some values, like device memory and connection type, aren't supported by every browser and will show as unavailable if your browser doesn't report them
- •The user agent string can be spoofed by browser extensions or developer tools, so treat it as a hint rather than a guaranteed fact about the underlying device
- •This information is often useful to include when reporting a bug or rendering issue to a website's support team

Frequently Asked Questions
Can this reveal my real IP address or exact location?
No. This tool only reads information your browser voluntarily exposes through standard JavaScript APIs, none of which include your IP address or precise geographic location.
Why do some fields say "not reported by this browser"?
Not every browser implements every API. Features like device memory and network connection type are part of newer or less universally supported specifications, so some browsers simply don't provide that information.
Is this data sent to a server?
No. Everything is read and displayed entirely locally in your browser using JavaScript. Nothing is transmitted anywhere, including to this website's own servers.
Why does the user agent look unusual or generic?
Some modern browsers intentionally simplify or freeze parts of the user agent string for privacy reasons, a trend known as user agent reduction, which limits how much identifying information websites can passively collect.
Can websites always see this much information about me?
Yes, essentially all of this information is available to any website you visit through standard JavaScript, which is part of why browser fingerprinting is a real privacy consideration on the web.
