Device Info Detector — Browser, OS, Screen, GPU

Detect device information in your browser: user agent, operating system, browser version, screen size, viewport, pixel ratio, GPU, battery, network, storage, permissions, and supported web APIs.

Useful device details

Browser and OS

Identify Chrome, Safari, Firefox, Edge, Android, iOS, macOS, Windows, Linux, and user agent details.

Display and viewport

Check screen resolution, viewport size, device pixel ratio, color depth, touch support, and orientation.

Hardware and network

Inspect CPU cores, memory hints, GPU renderer, battery state, connection type, and online status when available.

API support

See which browser capabilities are available for storage, clipboard, geolocation, notifications, media devices, and more.

FAQ

How do I find my browser and device info?

Open this detector and it reads available browser APIs to show your browser, OS, screen, user agent, GPU, network, and capability details.

Why is user agent detection sometimes wrong?

Modern browsers reduce or freeze user agent details for privacy. Feature detection is usually more reliable than parsing the user agent string.

Is my device information uploaded?

No. Detection runs locally in your browser and does not send device details to a server.
