Shadow is a discrete-event network simulator that directly executes real application code, enabling you to simulate distributed systems with thousands of network-connected processes in realistic and scalable private network experiments using your laptop, desktop, or server running Linux.

One open-source modeler for structures, heat and fluids, built from scratch in pure Rust: parametric part in, verified results out. Automatic all-hex and tet meshing, our own nonlinear implicit and explicit FEA, heat transfer and lattice Boltzmann CFD — every result checked against theory. For engineers and AI agents alike. Free, forever.

A high-performance engine for matrix math, physics simulation, and MCAD and ECAD as code. RunMat checks types, sizes and units before anything runs, executes on CPU and GPU, and runs existing MATLAB-language code as written.

Mission-control style spacecraft tracker in Rust: live ISS, Dragon, Hubble, JWST and Roman orbits, passes and schedules. Retro CRT themes, and a mode for Raspberry Pi + composite CRT.
