Sage

SageMath is a free, open‑source system for mathematical computation that integrates a wide range of existing libraries such as NumPy, SciPy, matplotlib, Sympy, Maxima, GAP, FLINT and R. Users interact with the combined functionality through a unified Python‑based language or via the interfaces that wrap each component, enabling symbolic algebra, numerical analysis, combinatorics, number theory and many other domains within a single environment.

The software targets students, educators, researchers and engineers who need a comprehensive toolkit for exploring mathematical concepts, producing graphics, and performing interactive calculations. It is distributed as macOS binaries and also available through conda‑forge, with additional options for Linux and Windows via the Windows Subsystem for Linux. Documentation, tutorials and a community mailing list support users from introductory to advanced levels.

SageMath aims to provide a viable free alternative to commercial packages such as Magma, Maple, Mathematica and MATLAB, while remaining under the GPL license and encouraging contributions through its GitHub repository and community channels.
