Is MatCraft open source?

Yes, MatCraft's core optimization engine is open source under the Apache 2.0 license. This includes the Python library (materia), which contains the surrogate model framework, CMA-ES optimizer, active learning loop, Pareto analysis, and all 16 built-in domain plugins.

What Is Open Source

• Core Library (src/materia/): All optimization, surrogate modeling, active learning, and domain plugin code.
