Rio
A hardware-accelerated GPU terminal emulator powered by WebGPU.
... to support WebAssembly runtime so in the future you will be able to define how a tab system will work with a WASM plugin written in your favorite language.
Rio uses WGPU, which is an implementation of WebGPU for use outside of a browser and as backend for firefox’s WebGPU implementation. WebGPU allows for more efficient usage of modern GPU’s than WebGL. Applications using WPGU run natively on Vulkan, Metal, DirectX 11/12, and OpenGL ES; and browsers via WebAssembly on WebGPU and WebGL2.
