Vercel AI Open-Sources vgpu: A TypeScript WebGPU Library for AI Agent Shaders

Vercel has open-sourced vgpu, a TypeScript WebGPU library for AI agent shaders, under an MIT license and published to npm at v0.3.1. The library treats .wgsl files as importable modules, runs the same shader in browser, headless Node.js, and CI snapshot tests, and ships a complete fullscreen effect in 25 KB gzipped. Vercel built vgpu internally to ship shaders on vercel.com and now offers it as a free library with no account or quota, including a CLI, llms.txt, and a hosted read-only MCP server.

Shaders are still the hardest thing to ship on a normal web team. WebGPU gives you the hardware, then hands you adapters, bind group layouts, and pipeline descriptors before a single pixel moves. Vercel spent that cost internally building the shaders on vercel.com, and has now open-sourced the result. is a TypeScript library that treats vgpu https://github.com/vercel-labs/vgpu .wgsl files as importable modules, exposes one Gpu context, and runs the same shader in a browser canvas, in headless Node.js, and in a CI snapshot test. Is it deployable? Yes , vgpu is MIT licensed https://github.com/vercel-labs/vgpu/blob/main/LICENSE and published to npm, so pnpm add vgpu is the entire acquisition path. It is a library, not a hosted service, so there is no account, quota, or inference bill. One context, no hidden global state init acquires an adapter and device and returns a single Gpu handle. Everything else hangs off it. The browser quick start in the README is four lines: js const gpu = await init ; const surface = gpu.surface canvas, { dpr: 1, 2 } ; const wave = gpu.effect WAVE WGSL, { set: { speed: 2 } } ; gpu.frame.loop = { wave.set { time: gpu.time } ; wave.draw ; } ; surface wraps the canvas and clamps device pixel ratio between 1 and 2. effect compiles WGSL into a fullscreen effect whose uniforms are addressed by their WGSL names through set . Frames are explicit: passes, clears, and draws are calls, never implicit scene-graph state. WGSL as a Module System The differentiator is shader tooling. .wgsl files import and export like TypeScript modules. vgpu resolves the module graph, reflects bindings, removes unused declarations, and emits compact shader source at build time. That removes the hand-written binding declarations that normally drift out of sync with the shader. The README states a complete fullscreen effect ships in 25 KB gzipped, and that the budget is enforced in CI. Three Runtimes, One API The package exposes subpath exports for vgpu , vgpu/node , vgpu/mock , vgpu/scene , vgpu/client , and vgpu/core . The Node path is Dawn-backed and renders offscreen: js const target = gpu.target { size: 256, 256 , format: "rgba8unorm" } ; const pixels = await target.read ; That is what makes CI rendering practical. pixelmatch and pngjs are direct dependencies of the published package, consistent with the documented workflow where CI compiles the shader, renders a headless frame, and compares the snapshot. The mock adapter is deterministic and exists for tests that should not touch a GPU at all. The Agent Surface Vercel calls this an agent-first library, and the packaging backs that up. The package ships a vgpu binary, so npx vgpu docs , npx vgpu examples , and npx vgpu check work without a global install. vgpu.sh publishes agents.md , llms.txt , and a full documentation export, plus a tokenless examples discovery API with an OpenAPI 3.1 description. A hosted read-only MCP server is available at vgpu.sh/api/mcp , and @modelcontextprotocol/server is a direct dependency. There is also an installable agent skill in the repo. Comparison Key Takeaways - Vercel open-sourced vgpu , the WebGPU library it built to ship shaders on vercel.com. - One API surface runs in the browser, in headless Node.js via Dawn, and in a deterministic mock. .wgsl files import and export like TypeScript modules, with reflection for bindings and layouts.- A complete fullscreen effect ships in 25 KB gzipped, a budget the repo says CI enforces. - MIT licensed, on npm at v0.3.1, with a CLI, llms.txt , and a hosted read-only MCP endpoint.
