Browser Info

What Browser Info shows

Browser Info collects the details your web browser exposes to any page and presents them in one readable table. That includes the raw and parsed user agent, the detected browser name and version, the rendering engine, your operating system, and the device type. It also reports environment values such as screen resolution and color depth, the current viewport size and device pixel ratio, your preferred languages, the resolved time zone, the number of logical CPU cores, approximate device memory when the browser exposes it, online status, whether cookies are enabled, your preferred color scheme, and whether the device reports touch support. Every value is read locally with standard JavaScript properties like navigator, screen, and window.matchMedia.

Why this is useful

Knowing exactly what your browser advertises is helpful when filing a bug report, reproducing a layout problem, confirming that a feature flag or responsive breakpoint is active, or checking that privacy settings behave the way you expect. Support teams frequently ask for a user agent string and screen size, and copying an accurate report is faster and less error-prone than describing your setup from memory. Developers can use it to sanity-check feature detection and to understand how the same site might appear on a different device.

Private by design

This page makes no external requests and stores nothing. All processing happens with in-browser JavaScript, so the information never leaves your device. That matters because device and browser fingerprinting are often built from exactly these values; seeing them yourself is informative, but sharing them with a server is not required here and never happens. One value is deliberately omitted: your public IP address. A browser cannot determine it without asking a remote service, which would break the no-requests guarantee, so it is intentionally left out. Treat this report as a local diagnostic snapshot rather than a complete identity — values can be spoofed by extensions or privacy tools, and absent fields simply mean your browser chose not to expose them.
