This is an interactive voxel renderer written in WebGPU. It uses a JavaScript port of Voxel Automata Terrain to generate 3D voxel fractals. The demo page is here.

While this demo is capable of running on integrated graphics, the performance is generally very slow. I would recommend running this on a browser set to use your discrete GPU. I developed and tested it on my laptop (iGPU: Ryzen 9 4900HS w/ Radeon Graphics, GPU: NVidia GeForce RTX 2060 with Max-Q design) and got reasonable results. All of the images on this page were rendered on my discrete GPU in about 10s @ 1024 samples / pixel.
The rendering code was written by me. It consists of a few fragment shaders for raytracing, sample accumulation, and post processing. It uses glMatrix for JS linear algebra operations. Other attributions for specific functions can be found in the source code.
