WebGPU Fingerprinting

WebGPU fingerprinting reads adapter information from the new WebGPU API. When available, it provides hardware details not exposed through WebGL.

Collected signals

Signal	Example
vendor	apple
architecture	common-3
device	(empty on most browsers)
description	(empty on most browsers)
features	Set of supported GPU features
limits	Max texture dimensions, buffer sizes, workgroup sizes

Availability

WebGPU requires a secure context (HTTPS) and is supported in:

• Chrome 113+
• Edge 113+
• Firefox (behind flag)
• Safari (partial, WebKit)

When unavailable, the collector returns { supported: false } with 0 entropy.

Entropy and stability

Property	Value
Entropy	~10 bits (when available), 0 (when not)
Stability	0.90
Typical duration	50-60ms

Usage

const fp = await neoprint.get({ collectors: ['gpu'] })
const gpu = fp.components.gpu.value

if (gpu.supported) {
  console.log(gpu.vendor)        // "apple"
  console.log(gpu.architecture)  // "common-3"
  console.log(gpu.features)      // supported feature set
}
