Welcome to OSCI, where commercial organizations are ranked by the volume of
their employees’ year-to-date open source contributions on GitHub, the leading
source code repository for free and open source (FOSS) projects.


OPEN SOURCE CONTRIBUTOR INDEX

Updated September 1st, 2021

The table below shows the OSCI ranking for GitHub activity in August 2021. The
leading organizations remain consistent once again this month, although a slight
decrease in growth of Active Contributors is noticeable. Additionally, Intel,
Tencent and Alibaba are progressing well above their closest neighbours in
growth figures this month.

About OSCI

To learn more about OSCI, take a look at this article in our blog section about
OSCI and why we created it.


HOW DOES OSCI WORK?

To create this index, we use publicly available GitHub commit event data from GH
Archive. This includes all year-to-date commits to public GitHub projects, which
generally correlates to them being open source. OSCI measures the Active
Contributors (10+ commits) and the Total Community (1+ commit) at each
organization. In the spirit of transparency in the open source community, the
query logic of OSCI is available on GitHub. The latest OSCI rankings are
published monthly. The archive of the previous rankings is stored on the OSCI
GitHub repo.


HOW ARE COMMIT AUTHORS LINKED TO COMMERCIAL ORGANIZATIONS?

The email domain of the commit author is used to identify their organization.
The goal of OSCI is to rank open source activity by commercial organizations, so
contributors with email addresses from universities, research institutions and
free email providers are not included.


WHO OWNS AND MANAGES OSCI?

EPAM is the company behind OSCI. Our team created OSCI because we believe it is
important to highlight the top contributing organizations who recognize the
value of open source as much as we do.

EPAM continuously supports internal Open Source culture and welcomes passionate
developers from the Open Source community. To learn about career opportunities,
