use JavaScript to detect GPU used from within your browser

webgl-detect-gpu.js

var canvas = document.createElement('canvas');
var gl;
var debugInfo;
var vendor;
var renderer;

try {
  gl = canvas.getContext('webgl') || canvas.getContext('experimental-webgl');
} catch (e) {
}

if (gl) {
  debugInfo = gl.getExtension('WEBGL_debug_renderer_info');
  vendor = gl.getParameter(debugInfo.UNMASKED_VENDOR_WEBGL);
  renderer = gl.getParameter(debugInfo.UNMASKED_RENDERER_WEBGL);
}

// Sample output:
//
// » console.log(renderer);
// ATI Technologies Inc. AMD Radeon R9 M370X OpenGL Engine

Hello anyone,

I have a data set of webgl debugger renderer similar to what is generated by this webgl-detect-gpu.js. My interest is to try and detect from this data which one is malicious or fraudulent. Does anyone has an idea how I could do that using a python script or bash script?

If can be usefull to anyone:
changing line https://gist.github.com/cvan/042b2448fcecefafbb6a91469484cdf8#file-webgl-detect-gpu-js-L8
to
gl = canvas.getContext('webgl', { powerPreference: "high-performance" }) || canvas.getContext('experimental-webgl', { powerPreference: "high-performance" });

allow you to create the canvas using the -if any- high performance GPU

Hey, thanks for putting this up! It really helped me.

Just wonder what the console output in M1, can anyone tell me?😊

The above script with M1:

{
  debugInfo: {
    UNMASKED_RENDERER_WEBGL: 37446,
    UNMASKED_VENDOR_WEBGL: 37445
  },
  renderer: "Apple M1",
  vendor: "Apple"
}

Or using https://github.com/pmndrs/detect-gpu

{
  "gpu": "apple m1 (Apple M1)",
  "isMobile": false,
  "tier": 1,
  "type": "FALLBACK"
}

@danigb thanks bro

Using this method on M1, sometimes getting Google SwiftShader

do you have vue3 version. thanks in advance

Just a note for anyone who'll use this to detect M1; I get the same as @danigb on Firefox, but on Chrome I get the following:

{
  debugInfo: {
    UNMASKED_RENDERER_WEBGL: 37446,
    UNMASKED_VENDOR_WEBGL: 37445
  },
  renderer: "ANGLE (Apple, Apple M1 Pro, OpenGL 4.1)",
  vendor: "Google Inc. (Apple)"
}

Can anyone tell me what will be the output for android phone and Windows desktop. Both for chrome and mozilla.
