Device Information

View browser-exposed device, screen, touch, language, timezone and online status information.

Why results may vary

Browsers do not expose exact CPU model, serial numbers or precise physical memory.

How to use this test

Open the page to view the device characteristics the browser is allowed to expose. Rotate or resize the window to see orientation and viewport values update.

How the measurement works

The dashboard reads standard navigator and screen properties including logical CPU count, approximate device memory when available, screen dimensions, pixel ratio, touch support, language and timezone.

How to interpret results

Values are browser-reported and privacy-limited. Logical CPU count is not an exact CPU model, and device memory may be rounded or unavailable by design.

Troubleshooting tips

If a value is unavailable, that usually means the browser does not expose it. Compare another browser before assuming the hardware itself is missing a capability.

QUESTIONS & FIXES

Common device info questions

View all 7

What device information can a website actually detect?

A browser can expose limited signals such as screen size, logical CPU count, approximate memory on some browsers, touch capability, language and device-pixel ratio. Exact hardware models and serial identifiers are intentionally restricted.

Why does device memory show an approximate value?

Browsers that expose deviceMemory intentionally return coarse buckets rather than exact installed RAM. This reduces fingerprinting risk and means the number should be treated as an estimate.

Why is logical CPU count different from my CPU core specification?

navigator.hardwareConcurrency reports logical processors available to the browser, which can include simultaneous multithreading and can be limited by the browser or environment.

Why can't the page show my exact CPU or RAM model?

Modern browsers intentionally limit hardware details for privacy. Logical CPU count and approximate memory may be exposed, but exact models and serial identifiers are not standard web data.
