Deep Hardware & Peripheral Diagnostics

Inspect every facet of your computer, tablet, or smartphone directly from your web browser. Our online hardware diagnostics workstation detects connected peripherals, multi-monitor configurations, audio subsystems, WebGPU graphics, and CPU architecture in real-time with 100% on-device privacy.

  • Multi-Device Peripherals: Detect connected speakers, headphones, microphones, webcams, and game controllers.
  • Display & Refresh Rate: Live measure screen refresh rate (60Hz, 120Hz ProMotion, 144Hz, 240Hz), color gamut (DCI-P3), and HDR support.
  • Graphics & Compute: Check WebGPU adapter details, WebGL 2.0 unmasked GPU vendor/renderer, and max texture dimensions.
  • Storage & Network: View browser storage quota (GB), used storage, live network bandwidth (Mbps), and ping latency (RTT).

What This Tool Inspects

Live on-device metrics and hardware capabilities:

  1. CPU & Architecture: Logical cores, RAM estimate, 64-bit architecture, Client Hints, and device model.
  2. Peripherals & Multi-Input: Audio outputs, microphones, webcams, gamepads, mice, stylus, and touch points.
  3. Displays & Monitors: Multi-monitor extended setups, pixel density (DPR), viewport vs screen dimensions.
  4. Security & Web APIs: WebAuthn biometrics (Touch ID / Windows Hello), WebAssembly SIMD, Web Bluetooth, and Web USB.

Frequently Asked Questions

No, all device and hardware specifications are read directly inside your browser using standard Web APIs. None of your data, specs, or peripheral details are ever transmitted to any server.

The tool utilizes the browser's Media Devices API (navigator.mediaDevices.enumerateDevices) to identify all active audio output devices (speakers, headphones, Bluetooth audio), audio input devices (microphones), and video input devices (webcams, cameras). It listens for connection events so plugging in a headset updates immediately.

For user privacy, web browsers mask exact device model names until permission is granted. Clicking the 'Unlock Hardware Names' button requests a temporary permission that immediately reveals exact hardware model names (such as AirPods, Logitech webcams, or external DACs) without recording any media.

The tool computes frame timestamp intervals using requestAnimationFrame to calculate the real-time refresh rate of your display, accurately detecting 60Hz, 75Hz, 90Hz, 120Hz (ProMotion), 144Hz, 165Hz, or 240Hz monitors.

Yes! You can click 'Copy JSON' to get raw machine-readable data for debugging, or click 'Export Report' to download a cleanly formatted text specification sheet for technical support or records.
