Your browser already knows a surprising amount about your device — and it shares a safe subset of it with every website you visit. This page reads only the standard, documented browser APIs (navigator, screen, Intl) and shows you exactly what a site can see.
What you will see below
Operating system and platform, browser name and version, device type estimate, CPU architecture where exposed, logical CPU cores (hardwareConcurrency), device memory where supported (deviceMemory), screen and viewport sizes, device pixel ratio, color depth, touch support, language, time zone, online status, cookie and Do-Not-Track state, and your full user agent string.
Why some fields say “not available”
Browsers intentionally restrict hardware details for privacy and security. Exact CPU model, RAM size and serial numbers are not exposed to websites. Safari and Firefox hide more than Chrome; Apple devices report limited memory values; mobile browsers may generalize the platform. “Not available” means the browser withheld it — not that your device lacks it.
How to use this report
Use the table for troubleshooting (“which browser am I on?”), for responsive design checks, or when support asks for your setup. Copy, download or print the report with the buttons above the results.
How it works
Open this page and the embedded script queries only documented browser APIs. Nothing is installed, no account is needed, and results reflect your current browser profile — including extensions, private mode and OS display scaling.
Limitations
Support varies by browser. Privacy features (tracking prevention, user-agent reduction, fingerprint randomization) can generalize or withhold values. Treat results as a best-effort live snapshot rather than a certified hardware inventory.
Privacy
Detection runs in your browser. We do not store fingerprints or device reports. The only network call any tool makes is the optional public-IP lookup on /my-ip (via a third-party IP API, disclosed in the privacy policy).
