Open source. Open possibilities.

Chitin is an open-source geometry-to-physics compiler that converts 3D assets, including meshes and Gaussian splats, into portable convex hull colliders.

A Rust port of the BepuPhysics v2 physics engine, translated line by line from the original C# library. It offers SIMD-optimized collision detection and constraint solving, lock-free multithreaded scheduling, spatial queries, and an optional Bevy plugin. Requires Rust nightly and supports macOS NEON or x86_64 SSE/AVX2.

MuJoCo is a general-purpose physics engine designed for fast and accurate simulation of articulated structures interacting with their environment.

A pure-Python scientific computing platform with 22 modules covering quantum, ML, statistics, ODE solvers, and more—zero runtime dependencies, with optional NumPy/SciPy adapters for validation and reproducibility.

A work-in-progress 2D game engine written in Java, designed for modularity and code-centric development without reliance on external libraries.

A simple framework for developing interactive applications, simulations, and video games, providing core engine functionality without a dedicated editor.
