🐙passagemath is open source mathematical software in Python, released under the GNU General Public Licence GPLv2+.

It is a fork of SageMath, which has been developed 2005-2026 under the motto "Creating a Viable Open Source Alternative to Magma, Maple, Mathematica, and MATLAB".

The passagemath fork uses the motto "Creating a Free Passage Between the Scientific Python Ecosystem and Mathematical Software Communities." It was created in October 2024 with the following goals:

• providing instant, modularized installation with pip from binary wheels,
  • this major project was started in May 2020 in the Sage codebase and completed in passagemath 10.5.29 (May 2025),
• establishing first-class membership in the scientific Python ecosystem,
• giving clear attribution of upstream projects,
• providing independently usable Python interfaces to upstream libraries,
• offering platform portability and integration testing services to upstream projects,
• inviting collaborations with upstream projects,
• building a professional, respectful, inclusive community,
• empowering Sage users to participate in the scientific Python ecosystem by publishing packages,
• developing a port to WebAssembly (Pyodide, emscripten-forge) for serverless deployment with Javascript,
  • passagemath 10.8.1 (February 2026) published the first packages in the prefix.dev emscripten-forge-4x channel,
• developing a native Windows port,
  • passagemath 10.6.1 (July 2025) published the first pip-installable wheel packages for native Windows on x86_64,
  • passagemath packages became available in the MSYS2 software distribution in November 2025.

Moreover, the passagemath project:

• provides a stable, frequently updated version of the Sage distribution,
• periodically merges the compatible changes from the SageMath project,
  • passagemath 10.8.1 merged SageMath 10.9.beta3 (January 2026),
• integrates additional mathematical software,
  • notably Macaulay2, a full set of GAP packages, and the Combinatorial Matrix Recognition library,
• curates a library of Sage user packages.

Full documentation is available online.

passagemath attempts to support all major Linux distributions and recent versions of macOS. Use of the full functionality on Windows currently requires the use of Windows Subsystem for Linux or virtualization.

Complete sets of binary wheels are provided on PyPI for Python versions 3.11.x-3.14.x for Linux and macOS, both for the x86_64 and ARM architectures. The Linux wheels are also suitable for use within Windows Subsystem for Linux (WSL). Python 3.10.x is still supported by the passagemath-10.6.x series.

Binary wheels for native Windows (x86_64, ARM) are gradually being made available since the passagemath 10.6.x series; see Using the modularized distributions.

Unless you need to install passagemath into a specific existing environment, we recommend to create and activate a fresh virtual environment over a suitable Python (3.11.x-3.14.x), for example ~/passagemath-venv/:

$ python3 --version
Python 3.12.7
$ python3 -m venv ~/passagemath-venv
$ source ~/passagemath-venv/bin/activate

Then install the meta-package PyPI: passagemath-standard

(passagemath-venv) $ pip install -v --prefer-binary passagemath-standard

Start the Sage REPL:

(passagemath-venv) $ sage

Alternatively, use a Python or IPython REPL, or use the Python kernel or the provided Sage kernel in Jupyter.

The passagemath/passagemath repository README provides detailed instructions:

• Running passagemath in the cloud (Google Colab, molab.marimo.io)
• Using the modularized distributions (some are available for native Windows)
• Building from source
• Traditional installation from source as Sage-the-Distribution

People all around the globe have contributed to the development of SageMath since 2005, and hence of passagemath.

See CONTRIBUTING.md for how you can contribute: to passagemath itself or the surrounding mathematical software landscape.

If you received an invitation to join the organization, note that we send out invitations to the organization:

• to key stakeholders of upstream projects that passagemath depends on, as a gesture of appreciation and to extend an invitation to collaborate,
• to contributors to the upstream SageMath project, in particular when we merge their nontrivial contributions that were accepted into SageMath into the passagemath codebase, as a courtesy,
• to authors and contributors of downstream packages that depend on SageMath / passagemath, as an invitation to the passagemath ecosystem,
• to downstream packagers.

As of 2026年02月07日, the passagemath GitHub organization had 145 members. Becoming a member of the passagemath GitHub organization is free and does not imply any obligations other than to adhere to the organization's Code of Conduct. Membership is private by default, i.e., only shown to other members of the organization.

The passagemath project is a major integrating force in the mathematical software landscape. There are many ways to contribute: Follow the #issue numbers to see how you can help; for example, by surveying software, building or extending interfaces, or contributing to distribution packaging.
