Back when I worked on WebGPU in Firefox, GPU debugging was pretty straightforward. You’d use a setting that enables API traces of WebGPU, give it a path, and it would produce a trace. Then you’d replay it in a standalone application that is easily ran from NSight/RenderDoc/PIX/whatever. Moreover, you could replay it on a different platform with a different API! It was a breeze. I bet it still works.
