Best alternatives to jax-js in 2026
Running machine learning code natively in a web browser usually means either shipping a Python backend or settling for TensorFlow.js's more limited API. jax-js brings the JAX programming model — the same array-and-autodiff style used by many serious ML research teams — directly into JavaScript, compiling your code down to run on the GPU via WebGPU. It reimplements JAX/NumPy-style array operations and automatic differentiation in pure TypeScript with zero dependencies, compiling numerical code to WebGPU (and WebGL/WebAssembly as fallbacks) so it runs client-side with real GPU acceleration. It's installable via npm (@jax-js/jax), MIT-licensed, and actively developed — 918 GitHub stars, frequent commits, with an in-browser REPL for trying it without any setup.
