Smelter
Smelter is a real-time video compositing toolkit for low-latency multimedia composition in live streams and pre-recorded videos. It lets developers combine live feeds, screen recordings, pre-recorded videos, audio, embedded websites, text, graphics, animations, transitions, overlays, and custom shaders into a single video composition or live stream. Smelter is designed for use cases that demand immediate responsiveness, such as live streaming, broadcasting, video conferencing, interactive webinars, meetings, and production studios. It supports multiple sources at the same time without frame drops, allows layouts to change on the fly, and can mix or enrich video content, both live and offline, before saving the result as a file. The toolkit offers a browser-based experience that runs high-performance video processing with WASM and can leverage GPU rendering through WebGL or WebGPU.

RunMat
RunMat (by Dystr) is a fast, free, open-source alternative for running MATLAB code.
Users can run their existing .m files with complete MATLAB language grammar and core semantics. No license fees, no lock-in. 300+ built-in functions supported.
RunMat is built with a modern Rust runtime featuring a tiered execution model: an interpreter (Ignition) for instant 5ms startup and a JIT compiler (Turbine/Cranelift) for hot paths. GPU acceleration is automatic via a fusion engine that detects elementwise operation chains and dispatches them as optimized GPU kernels across NVIDIA, AMD, Apple Silicon, and Intel GPUs through Metal, DirectX 12, Vulkan, and WebGPU. Up to 131x faster than NumPy and 7x faster than PyTorch on dense numerical workloads.
Runs everywhere: CLI, NPM package, Homebrew, Jupyter kernel, or instantly in the browser via WebAssembly + WebGPU. Single portable binary. MIT licensed.

Shaders
Shaders is a component-based library designed to bring GPU-accelerated visual effects directly into modern web applications, enabling developers and designers to create interactive, high-performance visuals using WebGPU in the browser. It provides a declarative system where users can compose effects such as animated backgrounds, image distortions, lighting effects, and dynamic UI elements as reusable components compatible with frameworks like React, Vue, Svelte, Solid, and vanilla JavaScript. It includes a visual design editor that allows users to experiment with effects in real time and then export clean, production-ready code that can be seamlessly integrated into frontend projects, reducing the need for low-level shader programming. It offers a growing library of presets and collections, allowing users to quickly implement complex visual styles such as gradients, holographic effects, liquid animations, and ASCII transformations without building them from scratch.

TypeGPU
TypeGPU is a TypeScript library that enhances the WebGPU API, allowing resource management in a type-safe, declarative way. It is designed to change the way developers work with GPU rendering and computing by bringing stronger structure, validation, and developer experience to WebGPU workflows. TypeGPU helps developers easily encode and decode GPU data, using typed binary so they do not have to think about raw bytes when writing GPU programs. Complex data types such as structs and arrays can be described directly, while TypeScript automatically validates outgoing and incoming data. It works on React Native through react-native-wgpu, expanding WebGPU development beyond the browser. TypeGPU’s roadmap is focused on end-to-end type safety on the GPU through interoperating primitives such as data structures, buffers, bind groups, a linker, functions, pipelines, and imperative code.
