About InnerSource Commons

InnerSource Commons is the world's largest community of InnerSource practitioners. It is dedicated to creating and sharing knowledge about InnerSource, the use of open source best practices for software development within the confines of an organization.
Founded in 2015, the InnerSource Commons is now supporting and connecting over 2500 individuals from over 750 companies, academic institutions, and government agencies. The InnerSource Commons Foundation was incorporated on February 19th, 2020 and is now a 501(c)(3) public charity.


InnerSource Commons Mission

Our mission is to establish a body of knowledge and to educate individuals, commercial and non-profit organizations, research centers, and other institutions about the successful adoption of InnerSource best practices.

We provide a safe environment for accumulating and sharing knowledge and experiences, finding best practices, building standards and tooling, producing educational materials, and fostering research to advance the understanding, adoption, and practice of InnerSource.

How We Work

The InnerSource Commons utilizes open source methods to provide organizations practicing InnerSource a forum for discussing and improving the practice of InnerSource through the sharing of experiences (under the Chatham House Rule), creation and review of InnerSource patterns, and the open exchange of ideas.

Interested individuals and companies are welcome to participate and contribute content to the ISC. In general, contributed content will be made available under the Creative Commons Attribution-ShareAlike 4.0 International License attributed to No fees are required to participate.
