How to Use

The Device & Browser Info tool provides an instant, comprehensive audit of your current browsing environment. It leverages modern Web APIs to extract technical details about your hardware, software, and network configuration.

How to use this tool

  1. Automatic Scan: Simply load the page. The tool automatically begins querying your browser for supported capabilities and hardware specs.
  2. Explore Categories: Review the dashboard cards to see details on your Browser Engine, Display, CPU, GPU, and Network.
  3. WebGPU Deep-Dive: If your browser supports WebGPU, a detailed limits panel will appear at the bottom showing advanced graphics parameters.
  4. API Support: Check the "Modern Web APIs" section to see which cutting-edge features (like WebAssembly or Bluetooth) are enabled in your current browser.

About This Tool

Understanding Browser Fingerprinting

Browser fingerprinting is a technique used by websites to identify and track users based on their unique device configuration. This tool shows you exactly what information your browser exposes to every website you visit.

Modern browsers have implemented "Anti-Fingerprinting" measures, such as capping the reported RAM at 8GB or genericizing the GPU vendor string. This tool provides the "Raw" data as seen by a web developer, allowing you to verify the effectiveness of your browser's privacy settings.

Why Use This Tool

Privacy-First Auditing

Unlike "What is my IP" sites that track your location and network history, our Device Info tool is 100% Client-Side. We do not use any external tracking APIs, and we never send your device identifiers to our servers. Your technical profile remains completely private.

FAQ

What information does this tool detect?
It detects the browser name and version, operating system, screen resolution, device pixel ratio, CPU core count, available memory, network connection type, GPU specs, and support for modern APIs like WebGPU, Service Workers, and WebAssembly.
What is this information useful for?
For developers: verify browser capabilities before using specific APIs. For technical support: share device information with your support team. For privacy: understand what data your browser exposes to websites.
Is any data collected or stored?
No. All detection is performed locally using browser APIs (navigator, screen, WebGL). No information is sent to servers. The page does not use cookies or tracking.
What is the device pixel ratio?
The Device Pixel Ratio (DPR) indicates how many physical pixels represent one CSS pixel. A DPR of 2 (common on Retina displays) means each CSS pixel equals 4 physical pixels (2x2). This affects image sharpness and responsive design.
