Helping you to contribute to the mission

Source code is spread around a broad spectrum of code hosting platforms and websites, and developed using a variety of version control systems. In order to collect and archive it properly, Software Heritage needs adaptors for each of the platforms and version control systems out there.  This is a humbling task, that needs expert contributions.


This is why we are partnering with funders around the world to provide grants for experts that are willing to engage with the long term mission of Software Heritage. This page lists these grant programs, together with the grants already awarded, and information on how to apply for the programs that are still open.

Making all software count

A grant from Alfred P. Sloan Foundation has been awarded to Software Heritage specifically to foster the emergence of a community of expert contributors to increase the coverage of the Software Heritage archive.

Founded in 1934 by industrialist Alfred P. Sloan Jr., the Foundation is a not-for-profit grantmaking institution that supports high quality, impartial scientific research; fosters a robust, diverse scientific workforce; strengthens public understanding and engagement with science; and promotes the health of the institutions of scientific endeavor.
