Overview

Product summary

Review the store description, core capabilities, and common use cases.

WebGPU Fingerprint Defender is a browser extension that lets you easily hide your real WebGPU fingerprint by reporting a random fake value.

This add-on adds a small noise to the actual fingerprint and renews it every time you visit a website or reload a page. With the browser's WebGPU API, in general, two types of fingerprints can be generated. One with WebGPU specs (constant metrics) and the other with an image that is rendered with the WebGPU API on a canvas. This extension can spoof both values at the same time. To disable this add-on, please visit the extensions page in your browser and then click on the disable button. Please note that this add-on does not have any options page.

This extension is made in collaboration with the author of "WebGL Fingerprint Defender":

Spoofs WebGPU browser fingerprint data to prevent websites from tracking users via WebGPU-based fingerprinting techniques

Websites can uniquely identify and track users by querying WebGPU API properties (hardware limits, rendered canvas data). This extension adds small random noise to these values, making the fingerprint change on each page load and preventing consistent tracking.

1. Extension installs and content scripts run at document_start on all pages. 2. The MAIN world script hooks WebGPU API prototypes (GPUAdapter, GPUDevice, GPUCommandEncoder, GPUQueue) with Proxy objects that add small random noise to returned values. 3. When a site queries WebGPU properties, it receives slightly altered values that differ each page load. 4. The isolated content script detects fingerprinting via postMessage and notifies the background. 5. If notifications are enabled, a desktop notification alerts the user. 6. User can click 'What is my Fingerprint' in popup to visit the test page and verify spoofing works.

Target users: Privacy-conscious web users who want to prevent WebGPU-based browser fingerprinting / Users already familiar with browser fingerprinting defenses (companion to WebGL Fingerprint Defender by same author)

Cannot verify the actual noise injection behavior at runtime without testing in a WebGPU-capable browser

Monetization

No paid features detected

No payment processing, subscription management, license checking, or feature gating exists. All keyword hits for 'pro' are false positives matching JavaScript code patterns like stopPropagation, __proto__, prototype, Proxy, properties. The popup has a voluntary 'Make a donation' button that opens the homepage with ?reason=support, but this is not a gated paid feature.
