Essential Open Source Software for Science (EOSS) (Discontinued)

Essential Open Source Software for Science (EOSS) is sponsored by Chan Zuckerberg Initiative. The Essential Open Source Software for Science (EOSS) program supports open source software projects that are critical to biomedical research. The goal is to provide resources for software maintenance, growth, development, and community engagement for these essential tools. This includes support for hiring developers, improving documentation, addressing usability and compatibility, onboarding contributors, or convening communities.

Essential Open Source Software for Science (EOSS) is sponsored by Chan Zuckerberg Initiative (CZI), The Kavli Foundation, and The Wellcome Trust. This program invites letters of intent for funding open-source software projects that are essential for biomedical research. The goal is to support software maintenance, growth, development, and community engagement for these critical tools, with an emphasis on projects that have demonstrated impact and potential for continued improvement.

Essential Open Source Software for Science is sponsored by Chan Zuckerberg Initiative. CZI's Essential Open Source Software for Science program supports software maintenance, growth, development, and community engagement for critical open source tools that are crucial to modern scientific research, particularly in the biomedical and scientific research and deployment fields.

Open Science Grants is a grant program from the Chan Zuckerberg Initiative (CZI) that funds tools, platforms, and organizations advancing the open and immediate sharing of scientific knowledge, processes, and outputs. CZI invests in infrastructure that makes the scientific process more open, reproducible, and collaborative, enabling scientists globally to build on each other's work. The program supports education and capacity building, open-source biomedical software, and reproducibility tools spanning areas such as single-cell genomics, bioimaging, and computational biology. Eligible applicants include academic institutions, nonprofits, and open-source scientific software projects demonstrating community impact. CZI maintains a publicly browsable directory of current and past grantees representing multiple funding cycles across its Essential Open Source Software (EOSS) and related programs.

Essential Open Source Software for Science (Cycle 6) is sponsored by Chan Zuckerberg Initiative, The Kavli Foundation, and The Wellcome Trust. This program supports software maintenance, growth, development, and community engagement for critical open-source scientific tools. It is framed as sustaining existing critical infrastructure rather than funding new tool creation.
