The Center for Open Science (COS) is seeking proposals for open-source development projects that will improve usability, interoperability, and research workflows on the Open Science Framework (OSF)—a free, open-source platform maintained by COS to support researchers throughout the entire research lifecycle, from study design and data collection to publication.

This opportunity is part of the National Science Foundation’s Pathways to Enable Open-Source Ecosystems (POSE) program, which supports the growth of sustainable, community-driven open-source infrastructure. Through this initiative, COS is investing in developer-led enhancements that respond to real user needs, strengthen open science practices, and ensure the long-term resilience of the OSF platform.

Through this call, COS seeks proposals that:

• Advance community-requested OSF features or integrations
• Improve usability, interoperability, or workflow support
• Strengthen the sustainability of the OSF open-source ecosystem

Selected development teams or individuals will receive funding to implement their proposals in close collaboration with COS and the broader OSF open-source community.

Who Should Apply?

We welcome applications from:

• Independent open-source developers
• Small development teams with experience building for research or collaboration tools
• Contributors with tools, services, or platforms that could integrate with or enhance OSF

Ideal applicants will have experience with technologies such as Python, JavaScript/TypeScript (Angular.js), Django, and open-source APIs. Projects should aim to support reproducibility, usability, and the sustainability of open infrastructure.
