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.", "body_md": "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.\n\nis a TypeScript library that treats [vgpu](https://github.com/vercel-labs/vgpu)`.wgsl`\n\nfiles as importable modules, exposes one `Gpu`\n\ncontext, and runs the same shader in a browser canvas, in headless Node.js, and in a CI snapshot test.\n\n**Is it deployable?**\n\n**Yes**,`vgpu`\n\nis [MIT licensed](https://github.com/vercel-labs/vgpu/blob/main/LICENSE) and published to npm, so `pnpm add vgpu`\n\nis the entire acquisition path. It is a library, not a hosted service, so there is no account, quota, or inference bill.\n\n**One context, no hidden global state**\n\n`init()`\n\nacquires an adapter and device and returns a single `Gpu`\n\nhandle. Everything else hangs off it. The browser quick start in the README is four lines:\n\n``` js\nconst gpu = await init();\nconst surface = gpu.surface(canvas, { dpr: [1, 2] });\nconst wave = gpu.effect(WAVE_WGSL, { set: { speed: 2 } });\ngpu.frame.loop(() => { wave.set({ time: gpu.time }); wave.draw(); });\n```\n\n`surface`\n\nwraps the canvas and clamps device pixel ratio between 1 and 2. `effect`\n\ncompiles WGSL into a fullscreen effect whose uniforms are addressed by their WGSL names through `set()`\n\n. Frames are explicit: passes, clears, and draws are calls, never implicit scene-graph state.\n\n**WGSL as a Module System**\n\nThe differentiator is shader tooling. `.wgsl`\n\nfiles import and export like TypeScript modules. `vgpu`\n\nresolves 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.\n\n**Three Runtimes, One API**\n\nThe package exposes subpath exports for `vgpu`\n\n, `vgpu/node`\n\n, `vgpu/mock`\n\n, `vgpu/scene`\n\n, `vgpu/client`\n\n, and `vgpu/core`\n\n. The Node path is Dawn-backed and renders offscreen:\n\n``` js\nconst target = gpu.target({ size: [256, 256], format: \"rgba8unorm\" });\nconst pixels = await target.read();\n```\n\nThat is what makes CI rendering practical. `pixelmatch`\n\nand `pngjs`\n\nare 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.\n\n**The Agent Surface**\n\nVercel calls this an agent-first library, and the packaging backs that up. The package ships a `vgpu`\n\nbinary, so `npx vgpu docs`\n\n, `npx vgpu examples`\n\n, and `npx vgpu check`\n\nwork without a global install. `vgpu.sh`\n\npublishes `agents.md`\n\n, `llms.txt`\n\n, 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`\n\n, and `@modelcontextprotocol/server`\n\nis a direct dependency. There is also an installable agent skill in the repo.\n\n**Comparison**\n\n**Key Takeaways**\n\n- Vercel open-sourced\n`vgpu`\n\n, 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.\n`.wgsl`\n\nfiles 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.\n- MIT licensed, on npm at v0.3.1, with a CLI,\n`llms.txt`\n\n, and a hosted read-only MCP endpoint.\n\nCheck out the [ GitHub Repo](https://github.com/vercel-labs/vgpu),\n\n[, and the](https://vgpu.sh/)\n\n**Docs and Examples**[.
