# Dawn, a WebGPU implementation

Dawn is an open-source and cross-platform implementation of the work-in-progress [WebGPU](https://webgpu.dev) standard.
More precisely it implements [`webgpu.h`](https://github.com/webgpu-native/webgpu-headers/blob/master/webgpu.h) that is a one-to-one mapping with the WebGPU IDL.
Dawn is meant to be integrated as part of a larger system and is the underlying implementation of WebGPU in Chromium.

Dawn provides several WebGPU building blocks:
 - **WebGPU C/C++ headers** that applications and other building blocks use.
   - The `webgpu.h` version that Dawn implements.
   - A C++ wrapper for the `webgpu.h`.
 - **A "native" implementation of WebGPU** using platforms' GPU APIs:
   - **D3D12** on Windows 10
   - **Metal** on macOS and iOS
   - **Vulkan** on Windows, Linux, ChromeOS, Android and Fuchsia
   - OpenGL as best effort where available
 - **A client-server implementation of WebGPU** for applications that are in a sandbox without access to native drivers
