The pandas Project will always be 100% open source software, free for all to use and released under the liberal terms of the modified BSD license. If you have found pandas to be useful in your work, research or company, please consider making a donation to the project commensurate with your resources. Any amount helps! All donations will be used strictly to fund the development of the pandas Projects’s open source software, documentation and community.

Donations are managed by the NumFOCUS Foundation, which is the legal and fiscal umbrella for the project. NumFOCUS is a 501(c)3 non-profit foundation, so if you are subject to US Tax law, your contributions will be tax-deductible.

More specifically, donations can be used to work towards major improvements of the pandas Project, including:

  • Fixing long-standing limitations or inconsistencies in missing data (null values in integer and boolean data, and a more consistent notion of null / NA).

  • Improved performance and utilization of multicore systems.

  • Better user control / visibility of memory usage.

  • Clearer semantics around non-NumPy data types, and permitting new pandas-only data types to be added.

  • Exposing a “libpandas” C/C++ API to other Python library developers.

More information about this can be found in the “pandas 2.0” design documents:
