Alternatives to SageMath
A free open-source mathematics system built on NumPy, SciPy, Maxima, GAP and many other packages. The listings below can replace it for an important use case. Each note says what changes if you switch.
The original
SageMath
A free open-source mathematics system built on NumPy, SciPy, Maxima, GAP and many other packages.
Replacements
Listings that take over the same core job as SageMath.
Wolfram|Alpha
A computational knowledge engine that answers math, science and everyday questions typed in plain language.
Wolfram|Alpha is a freemium web service answering plain-language math questions with step-by-step solutions, but it is proprietary and needs an internet connection.
Jupyter
Browser-based notebooks, JupyterLab and the classic Notebook, that combine live code, text and visualizations.
Jupyter is an open-source notebook environment for over 40 languages, suited to interactive computing, but it lacks SageMath's bundled mathematics libraries unless you add them.
Also worth comparing
These listings name SageMath as their own alternative, so the relationship runs both ways.
Julia
A fast, dynamically typed programming language for technical and scientific computing.
SageMath is a free mathematics system that combines many libraries behind a Python-based language, and on Windows it needs the Windows Subsystem for Linux to run.
R
A free software environment and language for statistical computing and graphics.
SageMath is a free mathematics system that combines many libraries behind a Python-based language and suits computer algebra. It is a large install and needs WSL on Windows.
