Show HN: MuJoCo React
noahwardlow Sunday, February 22, 2026
MuJoCo physics simulation in the browser using React.
This is made possible by DeepMind's mujoco-wasm (mujoco-js), which compiles MuJoCo to WebAssembly. We wrap it with React Three Fiber so you can load any MuJoCo model, step physics, and write controllers as React components, all running client-side in the browser
Summary
This article introduces a React-based wrapper for the MuJoCo physics simulation engine, enabling developers to easily integrate MuJoCo simulations into their React-based projects. The library provides a simple and flexible API for creating and controlling MuJoCo environments, making it a useful tool for building interactive simulations and reinforcement learning applications.
