WebGPU/WGSL Reference

What’s on this website?

This is a quick reference for WebGPU and WGSL, the WebGPU shading language. While the WebGPU specification aims to describe the API as accurately and detailed as possible, the reference provides an easy to navigate API summary for daily use. For now, this is not a detailed introduction or programming guide.

What is WebGPU?

WebGPU is a future web standard and JavaScript API for interfacing with the GPU, the graphics processing unit. It is based on concepts of other modern graphics APIs such as Vulkan, Metal, and Direct3D 12. The specification is under development.

• Click on any method name to expand all information you need in order to prepare the arguments for calling this method.
• Click on any type name to get detailed information about it.
