The Gephi Consortium

Leading Gephi development

The Gephi Consortium is a legal entity created to ensure future developments of Gephi, a world-class open source software, leader in the visualization and analysis of large networks in real-time. Like Photoshop™ but for data, Gephi helps data analysts to intuitively reveal patterns and trends, highlight outliers and tells stories with their data.

We are a not-for-profit corporation governed by the French law of July 1st, 1901, equivalent of the United States 501(c)(3) organization. The Gephi Consortium has officially started on October 1st, 2010. Learn more »

Our missions

  • The Consortium identifies strategic needs from the industry and research,
  • create standards to ensure interoperability,
  • organize the contributors to produce generic and reusable parts of Gephi,
  • help newcomers in using and integrating Gephi technologies,
  • and facilitate the recruiting of our skilled developers by our trusted partners.

The Gephi Consortium is guided by the principles of the Gephi Manifesto.

Why join the Consortium?

If you consider Gephi as a core technology for your business or your research like Quid, Inc. or the Center for Complex Networks and Systems Research, then you should become a member.

The Gephi projects are characterized by a collaborative, consensus based development process, an open and pragmatic software license, and a desire to create high quality software that leads the way in its field. We act as a central point to coordinate a worldwide distributed development and promote it. You could be interested by reading Dr. Tominski's review about the Gephi technology.


We provide a core technology for Visualization and Network Science research. Use Gephi as a platform for implementing new research ideas in a very short time, focus on your novelty, and get feedback from the community.

Join us to drive the project closer to the needs of your research teams, as you grant a seat at the Board of Directors. Benefit from the reputation of a worldwide known project, officially granted by Google Inc. during the Summer of Code since 2009, and awarded by Oracle Corp at JavaOne 2010.

Where will my membership funds go?

We focus on the specifications and development of the Gephi Open Source core. This distributed R&D effort for building generic and reusable parts is only made possible by the collaboration of multiple companies, research laboratories and organizations.

Your sponsorship will also allow the Gephi Consortium to:

  • Pay developers to code critical features required by the members
  • Set up a training program and student challenges with high quality standards
  • Represent the project in public and promote it to make the community grow.

While all of the administrative effort is currently through unpaid volunteers, we finally need financial assistance to keep our work running. Expenses include server costs, legal and accounting, and normal office expenses.
