OSF

The Open Science Framework is a platform for research collaboration that hosts project materials, data and a preprint registry. Its read API is keyless, letting our search query it directly. Useful for finding preprints and research project materials that never appeared in journals.

Why it’s useful & how it works

The Open Science Framework is a research collaboration and transparency platform where scientists share projects, preregistrations, data, materials, and preprints, often before or alongside formal publication. It hosts 14 community-specific preprint servers including PsyArXiv and SocArXiv, making it particularly valuable for psychology, social science, and education research. Echo queries the OSF API so you can find shared project materials and preprints; you then read and download directly on osf.io.

What’s inside

More than 500,000 registered users have created projects and deposited content on OSF since 2012. The platform has hosted more than 100,000 registered studies and tens of millions of shared data files.
