About the Open Source Initiative


As steward of the Open Source Definition, we set the foundation for the open source software ecosystem.

The Open Source Initiative (OSI) is a California public benefit corporation, with 501(c)3 tax-exempt status, founded in 1998.

We are also actively involved in Open Source community-building, education, and public advocacy to promote awareness and the importance of non-proprietary software. OSI participates in Open Source conferences and events, to meet with open source developers and users, and to discuss with executives from the public and private sectors about how Open Source technologies, licenses, and models of development can provide economic and strategic advantages.

Vision

As the leading voice on the policies and principles of open source, the OSI helps build a world where the freedoms and opportunities of open source software can be enjoyed by all. The OSI supports institutions and individuals working together to create communities of practice in which the healthy open source ecosystem thrives.

Mission

The Open Source Initiative (OSI) is a non-profit corporation with global scope formed to educate about and advocate for the benefits of open source and to build bridges among different constituencies in the open source community.

Open source enables a development method for software that harnesses the power of distributed peer review and transparency of process. The promise of open source is higher quality, better reliability, greater flexibility, lower cost, and an end to predatory vendor lock-in.

One of our most important activities is as a standards body, maintaining the Open Source Definition for the good of the community. The Open Source Initiative Approved License trademark and program creates a nexus of trust around which developers, users, corporations and governments can organize open source cooperation.
