WebGPU is not based on Metal. Apple did an experiment several years back in Safari which they called WebGPU at the time. It was effectively a thin wrapper around Metal, and so that's caused some confusion, but the actual W3C WebGPU spec has nothing in common with that experiment. It's a carefully selected set of features that are feasible to run effectively on Vulkan, Metal, and D3D12 and structured to feel like a web-native API.
