WebGPU (Experimental)

WebGPU is a modern graphics API designed with modern GPUs in mind and brings these powerful graphics capabilities to web browsers.

In browsers, WebGPU is built on top of DirectX 12, Vulcan, or Metal depending on your device.

WebGPU also provides graphics features not available with WebGL2. However, WebGPU isn’t as broadly supported by browsers as WebGLA JavaScript API that renders 2D and 3D graphics in a web browser. The Unity Web build option allows Unity to publish content as JavaScript programs which use HTML5 technologies and the WebGL rendering API to run Unity content in a web browser. More info
See in Glossary, and is considered experimental and not recommended for production usage.
