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.

Your Course to Open Source

Open Course banner

We're adding to our fully-online Open Source Technology Management courses to provide those pursuing a career around open source software even more options. In addition to our fully accredited, credit-barring courses offered through Brandeis University, we've developed six new "micro-courses." Taking just four weeks and guided by high-profile leaders in the open source community, you'll have the opportunity to explore the latest trends and techniques driving open source projects and companies. Case studies highlight real-world scenarios and solutions impacting the creation and delivery of open source software across industries. Group projects provide virtual teams direct experience in the highly collaborative, iterative, and innovative world of open source communities of practice.

And of course, just like our traditional courses, OSI members receive a 15% discount off the cost of our new micro-courses.

The Hard Work of Critical Conversations in Open Source

Open source is bigger and more diverse than ever before. With that success comes challenges, some new and some old, but all of them on a larger scale than ever before.

As we grow and convene more people and viewpoints, the conversations will get more difficult. In some ways, that’s good--vigorous discussions help us clarify our shared understanding and pushing the boundaries helps us find where those boundaries are. We evolve appropriately to meet the needs of a changing world.
