Device Information
What Is the Device Information Viewer?
The Device Information Viewer is a client-side tool that reads your browser and device properties using standard Web APIs such as the Navigator API, Screen API, WebGL, and the Network Information API. It displays a structured overview of your current browser identity, screen dimensions, system hardware, and GPU capabilities. All data is collected locally in your browser — nothing is sent to any server.
How to Use the Device Information Viewer
- Open the tool — your device information is automatically detected and displayed.
- Browse through the four sections: Browser, Screen, System, and GPU.
- Click the copy button next to any value to copy it to your clipboard.
- Click the Refresh button to re-read all values (useful after resizing the window or changing orientation).
- Use the displayed User Agent string and screen details for debugging responsive layouts or browser-specific issues.
Common Use Cases
- Bug Reports & Support Tickets — Quickly gather your exact browser version, OS platform, screen resolution, and GPU info to include in bug reports or support tickets for accurate reproduction.
- Responsive Design Testing — Check your actual screen dimensions, pixel ratio, and orientation to verify how your website is being rendered on the current device.
- Performance Diagnostics — View CPU core count, device memory, GPU renderer, and network connection type to understand performance characteristics of the current device.
- User Agent Verification — Inspect the full User Agent string and parsed browser name/version to debug UA-sniffing logic or verify feature detection results.
FAQ
Is any data sent to a server?
No. All information is read using browser-native JavaScript APIs and stays entirely in your browser. Nothing is transmitted to any external server.
Why do some values show N/A?
Some APIs like Device Memory and Network Information are not supported in all browsers (notably Safari and Firefox). When an API is unavailable, the tool displays N/A instead.
How accurate is the GPU information?
GPU information is read via the WEBGL_debug_renderer_info WebGL extension. Most desktop browsers expose the real GPU name, but some privacy-focused browsers or configurations may mask or hide this data.
Does the screen size change when I resize the browser window?
Screen width and height reflect the physical display dimensions, not the browser viewport. They remain constant regardless of window size. The pixel ratio may change if you move the window to a display with a different DPI.
