wasi-gfx-runtime Native host implementation of the wasi-gfx and wasi:webgpu interfaces.
wasi-gfx-shim Shim for running wasi-gfx components on the web.
wasi-gfx-js Implements the WebGPU JS API on top of wasi:webgpu, for writing wasi-gfx components in JavaScript/TypeScript.
wasi-webgpu-headers Implements webgpu.h on top of wasi:webgpu.

History

wasi-gfx:surface and wasi-gfx:frame-buffer were originally part of the core WASI standard. They've been moved into this dedicated namespace to allow faster iteration — versioned like a library rather than a rigid standard, while staying fully committed to the Wasm Component Model.

wasi:webgpu remains an official WASI spec (it maps directly to the stable WebGPU web standard).
