PhaseFieldX vs py-pde
Both stand on physics simulation software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan LinuxMacSelf-hosted
PhaseFieldX provides a documented, open-source workflow for phase-field material simulations and visualization. Its setup depends on FEniCSx, while some listed applications remain upcoming.

py-pde offers a broad finite-difference toolkit with multiple fields, geometries, solvers, and computational backends. Its documented scope is narrower for unsupported equation types and requires caution when arbitrary expressions could contain malicious input.
