OSI Affiliate Membership

The OSI Affiliate Scheme allows non-profit and not-for-profit organizations to become OSI members. Affiliate membership is an ideal way for open source projects and the communities that support them to support the mission of the OSI and contribute to the continued awareness and adoption of open source software.

Affiliate Membership is available for:

  • open source projects & communities
  • educational institutions (K12 & Higher Ed.)
  • user groups


The program is now open for applications. Please see the links below for details.
