COS is dedicated to improving the alignment between scientific values and scientific practices. As a non-profit technology start-up, our team moves quickly from problem to solution, and continuously evaluates and improves our solutions. We blend science and technology in support of open science - transparency and inclusivity.

Who We Work With


Research can be arduous; COS wants to make scientists' lives easier by simplifying their workflow. Learn how we're doing that.

Publishers & Societies

COS has built free, easy-to-adopt tools for journals and societies to incentivize preregistration and sharing of data and materials. Read more.


COS builds open source infrastructure for science, connects via API with other services, and supports open projects. Find out how you can get involved.

What We Work On


We conduct research on scientific practices and provide grants for relevant endeavors. Most projects are open, crowdsourced efforts. See some examples.


COS is fostering community among open-source developers, open science researchers, and the broader scientific community. Visit our Google group for the Open Science Collaboration. Read more about our community efforts.


We support and improve the scientific workflow by connecting technologies that researchers use. See our work at the Open Science Framework and check out some of our other projects.
