Pro Tips
- •Device Memory and Connection Type aren't supported in every browser - Safari and Firefox don't expose these for privacy reasons, so they'll show as unavailable there
- •Values like Device Memory and CPU Cores are approximate and sometimes deliberately capped by the browser to reduce fingerprinting risk
- •Viewport Size updates only on page load - resize your window and reload to see a new reading
- •All of this information is already visible to any website you visit, since it comes from standard browser APIs, not anything special this tool accesses

When to Use This Tool
Check your actual viewport size and pixel ratio when a layout looks wrong.
Copy your exact browser, OS, and screen details to include in a bug report.
See whether your browser exposes device memory, connection type, or touch support.
Confirm exactly what user agent string your browser is sending to websites.
How It Works
Read standard browser and screen properties exposed by the Navigator, Screen, and Intl APIs
Display each value in a readable table format
Refresh the values only when the page loads, since most of these properties don't change during a session
100% Private
Files never leave your device. All processing happens locally in your browser.

Frequently Asked Questions
Why do some values show 'Unavailable'?
Some browsers, especially Safari and Firefox, don't expose properties like Device Memory or Connection Type at all, as a privacy measure against browser fingerprinting.
Is this information sent to a server?
No. Everything is read directly from your browser's own APIs and displayed locally - nothing is transmitted anywhere.
Why is my CPU core count lower than I expect?
Some browsers cap the reported hardwareConcurrency value below your device's actual core count to reduce fingerprinting surface.
Can a website see all of this about me?
Yes, all of these values come from standard, publicly accessible browser APIs, so any website you visit can read the same information your browser exposes here.
