What's Good
Apache-2.0. 2D and 3D, joints, SIMD, optional determinism. Native Rust and WASM builds. Dimforge stack next to nalgebra.
The Catch
Rust/WASM 2D+3D with joints/SIMD/optional determinism — Matter.js is MIT 2D only. Planck covers the same 2D JS slot as Matter. Distinct from Matter.js.
Verdict
Apache-2.0 2D+3D physics. Not Matter.js 2D.
