Spektral is a focused WebGPU library for fullscreen WGSL shaders. It gives you a framework-neutral runtime and first-class adapters for Svelte, React, and Vue, without the scene graph and 3D tooling of a general-purpose engine.
Use it for shader-driven visuals, generative art, procedural textures, post-processing, feedback effects, and GPU compute. Spektral handles the canvas, render loop, scheduling, and GPU resources while your application owns the shaders and interaction.
npm install spektralImport from the entry point that matches your application:
| Application | Entry point |
|---|---|
| Framework-independent | spektral |
| Svelte | spektral/svelte |
| React | spektral/react |
| Vue | spektral/vue |
- Validated WGSL materials for fullscreen rendering
- Runtime updates for uniforms, textures, and storage buffers
- Render, feedback, and compute passes for multi-step GPU work
- Explicit render modes and a scheduler for frame-level control
- Source-mapped shader diagnostics and inspectable render-graph snapshots
- The same core API across Svelte, React, and Vue
Spektral needs WebGPU and a secure context such as HTTPS or localhost. It is built for fullscreen shader and compute workflows. If your project needs meshes, cameras, lighting, or a scene graph, a 3D engine will be a better fit.
Start with the installation guide, then use the full documentation for materials, shaders, passes, runtime behavior, and API contracts. You can also explore complete applications in the playground.
