About Us

Open Source Contributor Index tracks and measures open source activity on GitHub by commercial organizations. It allows organizations, communities, analysts and individuals involved in open source to gain up-to-date insights through an intuitive interface, clear visualizations and advanced filtering.

How does OSCI work?

To create this index, we use publicly available GitHub commit event data from GH Archive. This includes all commits to public GitHub projects. OSCI measures the active contributors (10+ commits) and the total community (1+ commit) at each organization

Real-time data from GitHub archive

With OSCI, you can get a visual of the real-time rank of your organization in the open source community based on the number of commits made by your employees on GitHub. This allows you to find your own organization's ranking and observe trends in contributions, licenses, and languages.

Transparency in measurements

OSCI ranks organizations based on two measurements. The first is the number of people who authored 10 or more commits in the current year, in other words - active contributors. The second is the number of people who made at least one commit in the year - the total community; replacing the need for intensive manual analysis.

Who we are

Launched in 2019 by EPAM Systems, the ongoing maintainers of OSCI, the index serves as a reference for the global OS community providing insights into industry trends and commercial Open Source engagement.

At EPAM we believe that better software makes great business sense. Recognising global collaboration and contributions to open source remains our key motivation behind OSCI.
