Muwanx is a browser-based mujoco playground powered by mujoco_wasm and ONNX Runtime. It enables MuJoCo simulations with real-time trained policy control, running entirely in the browser - no server for simulation required.
Perfect for sharing interactive demos as static sites (such as GitHub Pages), rapidly prototyping RL policies, or building customizable environments for experimentation and visualization.

• Real-time: Run MuJoCo simulations with real-time policy control.
• Interactive: Change the state of objects by applying forces.
• Cross-platform: Works seamlessly on desktop and mobile devices.
• Client-only: All computation runs in the browser. No server for simulation is required.
• Easy Sharing: Host as a static site for effortless demo distribution (e.g., GitHub Pages).
• Customizable: Add your own MuJoCo models and ONNX policies quickly.
