To promote and protect open source software and communities...

For over 20 years the Open Source Initiative (OSI) has worked to raise awareness and adoption of open source software, and build bridges between open source communities of practice. As a global non-profit, the OSI champions software freedom in society through education, collaboration, and infrastructure, stewarding the Open Source Definition (OSD), and preventing abuse of the ideals and ethos inherent to the open source movement.

Open source software is made by many people and distributed under an OSD-compliant license which grants all the rights to use, study, change, and share the software in modified and unmodified form. Software freedom is essential to enabling community development of open source software.

An Appeal From The OSI President

I want to write to you a triumphant message about what a wonderful year it has been for open source and the Open Source Initiative (OSI). There has been a lot to celebrate as an organization and a community. More than 600 of you are now members of the OSI, making us stronger than we’ve ever been before. We have increased staffing capacity, which makes it so we can do more of the necessary work to fulfill our mission. Open source adoption is on the rise and people continue to do amazing, innovative things with open source technology.

Luis Antonio Galindo Castro is an OSI Member and you should be too!

For almost 20 years Luis Antonio Galindo Castro has been an intense user of Free Libre Open Source Software (FLOSS), and for eight of those years--since the founding of our membership program--he's been an OSI Individual Member. We hope you too, as an intense user of FLOSS, will join us as an OSI member.
