Device Information

See exactly what your browser and device report about themselves — user agent, platform, screen resolution, hardware and network — read live from your browser and displayed instantly. Nothing is uploaded: every value comes straight from navigator and screen in your own browser.

How do I use it?

Open the tool and the report fills in immediately — no button to press. It stays live: resize the window, rotate your device, switch color scheme, or go offline, and the affected rows update on their own. Click Copy report to copy every field as plain text, ready to paste into a support ticket or bug report.

What's included?

• Browser & OS — user agent string, browser vendor, platform, preferred languages, timezone, cookie and Do Not Track status, online state.
• Screen & window — screen resolution, available screen size, current window size, color depth, device pixel ratio, orientation, and your color-scheme and reduced-motion preferences.
• Hardware & network — logical CPU core count, device memory (where the browser exposes it), touch support, and connection type/speed (where available).

Why do some values say "unknown"?

A handful of fields — device memory, connection type/speed, and orientation on some desktop browsers — are non-standard APIs that only a subset of browsers implement (mainly Chromium-based ones). When your browser doesn't expose a value, the tool shows "unknown" rather than guessing.

Is this the same as a User-Agent string?

No — it's broader. A User Agent Parser decodes a UA string you paste in (useful for parsing someone else's request log). This tool reads your own browser's live state directly, including screen and hardware details a UA string never carries.

Is anything sent to your servers?

No. Every value is read with client-side JavaScript and stays in your browser. Copying the report puts it on your clipboard only — nothing is transmitted anywhere.
