Open source Yes (BSD-3-Clause) Yes (BSD-3-Clause) Yes (GPL-2.0-or-later) Yes (MIT)
Best for Python developers who need numerical and statistical primitives underneath higher-level analytics tools. Python-based analysts and econometricians who need rigorous statistical inference, not just predictive accuracy. Statisticians, academic researchers, and analytics engineers doing custom statistical modeling and visualization. Quantitative researchers and engineers needing high-performance statistical simulation without dropping to C.
