Meta's decade-long support for the PSF underscores the importance of corporate investment in open-source stability. This commitment ensures that Python remains a secure, high-performance, and innovative tool for the global engineering community, particularly in AI and infrastructure.
This year marks Meta’s 10th consecutive year as a sponsor of the Python Software Foundation (PSF), the charitable organization dedicated to advancing, supporting, and protecting the open-source Python programming language and the community that sustains it. Python is one of the world’s most influential programming languages, and we use it across our engineering stack, from the backend of our apps and products like Instagram and Threads to cutting-edge AI research.
We recognize the vital role the PSF plays in sustaining the language, nurturing its global community, and driving innovation. After a decade, it felt like the right moment to reflect on why we, as an organization of engineers, are committed to funding the PSF. By supporting the PSF, we aim to help ensure that Python remains robust, innovative and accessible for generations of engineers to come. We hope our involvement will inspire other individuals and organizations to join us in strengthening the foundation that supports so much of today’s technology.
Python is the most used programming language at Meta. It powers infrastructure across our most important products and initiatives and supports a wide range of teams across the company. Some of the core maintainers of Python are Meta engineers who have authored new features and Python Enhancement Proposals (PEPs) for the Python community. PyTorch, one of the world’s most widely-used machine learning frameworks, was originally developed at Meta in partnership with the community before being spun off into its own independent foundation. Meta also builds open-source Python developer tools to help developers write better quality, more performant Python. This includes projects like Pyrefly, an incredibly fast type checker and language server.
Supporting the continued growth and sustainability of Python is a natural fit for Meta’s technical vision. It will continue to play an important role in helping us achieve our goals as we invest further in AI, build new data-driven products, and further scale our infrastructure.
At Meta we understand that using open source software like Python comes with a shared responsibility to help ensure the language and its ecosystem remain healthy, secure, and innovative for everyone. Every product shipped, every model trained, and every insight generated with Python is made possible by the collective work of the open source community, backed up by the organizational support and infrastructure maintained by the PSF. For Meta, supporting the PSF is a strategic investment in the future of Python, and hence the long-term stability of our own technology stack.
Our sponsorship of the PSF has helped fund impactful initiatives such as the Developer-in-Residence program, which employs full-time developers who are focused on improving the Python programming language and its ecosystem. This program has been transformative, allowing critical work to happen that would otherwise fall to overstretched volunteers or go unaddressed entirely.
PSF funding also goes towards strengthening the core infrastructure of the Python ecosystem, most notably the Python Package Index (PyPI), where our sponsorship has helped fund essential security enhancements. These improvements are vital for protecting the global Python community and ensuring that developers everywhere – including our own engineers – can safely share and consume packages.
Beyond purely technical investment, Meta’s support also helps fund educational programs and community events like PyCon US, where we’ve provided free and discounted passes to PyCon, supported workshops and summits, and contributed to fundraising efforts for groups like PyLadies. These investments help grow the Python community and foster the new talent that is essential for Python’s long-term sustainability.
In short, sponsorship of the PSF is a valuable investment in the tools and community that make our work possible.
There are several ways you as an individual, or your organization as a whole, can contribute to the ongoing success and sustainability of the PSF:
As an organization the most meaningful way for you to support the PSF is through annual sponsorship. Besides benefitting from the continued success of the Python language itself, there are a range of additional benefits depending on your sponsorship amount. Sponsors of the PSF receive public recognition, with their names and logos featured on the PSF website, in annual reports, and at major events. Sponsorship also provides valuable opportunities for community engagement, allowing organizations more opportunities to connect with the global Python community, participate in events, and demonstrate their commitment to open source. Higher-tier sponsors benefit from increased brand visibility through prominent logo placement and may be invited to speak or participate in special initiatives.
Finally, we want to say thank you to the Python community: the maintainers, contributors, educators, and advocates who make Python what it is today. Your passion and dedication are the foundation of Python’s success, and we’re proud to be able to support you, both as collaborators and sponsors.
