We’re so glad you’re here! For Full open-source community documentation, please see our Community Repo

The Center for Open Science (COS) is a nonprofit organization dedicated to increasing openness, integrity, and reproducibility of research. Our flagship platform, the Open Science Framework (OSF), supports researchers across the full research lifecycle—from planning and preregistering studies, to sharing data, code, and preprints.

This GitHub space is home to the open-source development behind OSF and related tools. We welcome contributions and collaboration from researchers, developers, community builders, and anyone interested in open science.

🧪 What is the Open Science Framework (OSF)?

The Open Science Framework (OSF) is a free, open-source platform designed to help researchers plan, collaborate on, and share their research. It promotes open science by supporting transparency, reproducibility, and collaboration.

Key features of OSF include:

• Project management & collaboration (OSF Projects) – Organize research projects and manage contributors.
• Archive of Registrations and Preregistrations (OSF registries) – Create a timestamped read-only version of a research protocol to promote transparency in the research process.
• Preprint hosting (OSF Preprints) – Share preprints to get early feedback.
• Open access & sharing – Control who sees your data, code, and protocols.
• Data storage & archiving – Store and preserve research outputs.
• Integrations – Connect tools like Google Drive, Dropbox, GitHub, Mendeley, and so many more!.

👉 Glossary of OSF Terms

OSF is powered by several open-source repositories maintained here on GitHub. These services work together to deliver OSF's platform functionality:

• osf.io[link coming soon] – The core backend platform (Python/Django)
• osf-angular – The modern Angular-based frontend
• waterbutler – Unified file storage and transfer API
• gravy-valet – Add-on integrations and service coordination

👉 Learn how these tools work together

We welcome contributions from all backgrounds! Whether you’re a developer, designer, researcher, or open science enthusiast, there’s a place for you here.

Start with our Contributing Guide to learn how to:

• Set up a local dev environment
• Submit issues and feature requests
• Make your first pull request

Please read our Governance Document to understand how decisions are made and how community members can get involved.

We’re building an open and welcoming community around this project — and we’re excited to invite broader participation soon!

🚀 Please note:
Right now, our community space is private while we kickstart a few initial projects and set the foundation for future collaboration. We expect to open the community to the public once the first projects are up and running.

If you're interested in staying in the loop or receiving an early invite when we launch, feel free to reach out to us! You can email our Technical community manager directly if you are interested in participating (daniel@cos.io).

Thanks for your interest and excitement — we’re just getting started!
