A new library, react-native-webgpu, exposes the WebGPU API to React Native apps.
Think of WebGPU as the next generation of graphics APIs for the web โ and now, potentially, mobile. Itโs designed to give developers more direct access to the GPU, with better performance and more flexibility than older APIs like WebGL.

โก๏ธ ๐ช๐ฒ๐ฏ๐๐ is built on top of OpenGL ES, which was originally designed over two decades ago. It abstracts a lot of GPU details to make things easier โ but that also limits what you can do and how efficiently you can do it.
โก๏ธ ๐ช๐ฒ๐ฏ๐๐ฃ๐จ, in contrast, is modeled after modern low-level graphics APIs like Metal (iOS), Vulkan (Android), and Direct3D 12 (Windows). These APIs give developers finer-grained control: you explicitly manage memory, schedule commands, and control how resources flow through the GPU.

The react-native-webgpu library brings WebGPU to mobile by using Dawn, Googleโs native implementation of the spec. This allows JavaScript code in your React Native app to speak directly to the GPU โ using the same API shape as in the browser.
In practice:
โก๏ธ On iOS, WebGPU calls are routed through Metal
โก๏ธ On Android, they go through Vulkan
This happens under the hood โ the JavaScript code you write uses familiar WebGPU methods (requestAdapter, requestDevice, command encoders, etc.), and Dawn takes care of translating those into native calls.
Once the GPU context is created, the flow is nearly identical to WebGPU on the web:
โก๏ธ You request an adapter and device
โก๏ธ Configure the GPU canvas context (format, alpha mode, etc.)
โก๏ธ Write your shaders in WGSL
โก๏ธ Build a render or compute pipeline
โก๏ธ Encode commands and submit them to the GPU
โก๏ธ Manually call context.present() to display the frame
๐ช๐ต๐ฎ๐ ๐๐ต๐ถ๐ ๐ฒ๐ป๐ฎ๐ฏ๐น๐ฒ๐:
โก๏ธ Real-time rendering with full GPU control.
โก๏ธ Custom 3D engines or rendering pipelines.
โก๏ธ Compute-heavy workloads (e.g., physics, simulations, image transforms).
โก๏ธ Potential for code sharing between Web and mobile using the same WebGPU pipeline.
This isnโt a plug-and-play UI solution โ but for apps pushing visual or compute limits, it opens the door to GPU-native performance on mobile.
Do you have any features or projects where direct access to the GPU would make a difference?
