The Foundation provides an established framework for intellectual property and financial contributions that simultaneously limits contributors potential legal exposure. Through a collaborative and meritocratic development process, Apache projects deliver enterprise-grade, freely available software products that attract large communities of users. The pragmatic Apache License makes it easy for all users, commercial and individual, to deploy Apache products.

The Mailman project develops the GNU Mailman mailing list manager. Our goals are RFC conformance and powerful convenient tools for subscribers, moderators, list owners, domain administrators, and site adminstrators of mailing lists.
Konflux is an open source, opinionated Kubernetes-native software factory built on Tekton, focused on software supply chain security. It provides an end-to-end pipeline: hermetic builds from source, cryptographic signing, provenance attestation, vulnerability scanning, policy verification, and release automation. Konflux integrates with the broader supply chain security ecosystem (Sigstore, SLSA, Conforma) and is built by a welcoming community that values collaboration, transparency, and mentorship.
Contributors work with cutting-edge cloud-native technologies and help shape how we solve one of the most critical challenges in modern software delivery.
Learning Unlimited's mission is to create educational opportunities for high school and middle school students, and to provide leadership and teaching opportunities for college students. Learning Unlimited strives to engage students of all ages in an educational setting to share and discover their passions. To accomplish this, Learning Unlimited links local universities with their communities. Our open source work revolves around building and maintaining website infrastructure for these chapters to use.
MalariaGEN is a global network of global partners who share and integrate data relevant to inform malaria surveillance, our mission is to generate insights and tools that bridge the gaps for analysts in malaria endemic settings to use their data meaningfully to inform public health efforts. We build and optimise data resources and analytical tools to run directly in the cloud. Our flagship project is the Vector Observatory, which includes whole-genome sequence data for over 30,000 mosquitoes, integrating data from 70 partners across the globe from over 17 different mosquito species -- this is the largest resource on genetic variation data for any multicellular organism (other than humans!). Our goal is to enable analysts, scientists, students and public health practitioners to access these data without the need for any dedicated compute infrastructure, by optimising our resources to run within free compute environments (a big shout to Google Colab!) and by developing training resources that support partners to get confident with using cloud-native data and resources for their analysis.
Metaflow is a human-friendly Python library that makes it straightforward to develop, deploy, and operate various kinds of data-intensive applications, in particular those involving data science, ML, and AI. Metaflow was originally developed at Netflix to boost the productivity of data scientists who work on a wide variety of projects, from classical statistics to state-of-the-art deep learning.
MLLAM is a collaborative community dedicated to advancing machine learning applications in weather forecasting, specifically for Limited Area Modeling (LAM). The organization hosts several open-source key repositories, including neural-lam, which focuses on neural weather prediction using graph-based models. Members are from various research institutions and national weather services committed to improve weather forecasting at regional, high-resolution scale.
mofa-org is an open-source organization that builds and maintains the MoFA ecosystem — a modular AI agent framework that makes it easy to build, compose, and run complex AI applications & a collection of open-source tools and frameworks designed to:
Moganlab develops Mogan STEM, a professional scientific writing platform specifically designed for mathematics, physics, statistics, and computer science, targeting complex formula-based documents. It is deeply optimized from GNU TeXmacs, with emphasis on performance and user experience. With Mogan STEM, you can create documents 100 times faster than LaTeX
preCICE is an open-source coupling library and ecosystem for general partitioned multi-physics and multi-scale simulations, including surface and volume coupling.

The Open Source Team at the United Nations, based within the UN Office of Information and Communications Technology (UNOICT), supports the development and adoption of open source technologies across the UN system and in collaboration with external partners. The team works to advance digital public goods that address global challenges such as climate resilience, sustainable food systems, and inclusive digital participation.
Through initiatives including “Reboot the Earth” and other open source collaborations, our team enables early-stage ideas to mature into scalable, production-ready solutions. Our work emphasizes open collaboration, responsible use of emerging technologies such as AI, focusing on deployment in real-world, resource-constrained environments. The Open Source Team also provides technical guidance, mentorship, and governance support to ensure projects not only align with UN values but also prioritize long-term sustainability.
