Please do not ask the OSI about obtaining a specific piece of software or a customized licensing arrangement for that software. The OSI does not write or offer software, nor are we the authors of the licenses listed here -- we simply evaluate those licenses for compliance with the Open Source Definition. If you have questions about a particular piece of software, you should contact the provider of that software.

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.
