Are Proprietary Graph Databases Holding You Back?

Lack of Transparency. Proprietary. Big License Costs.

Do you want to use a graph engine that does not rely on indexes for traversal?

What Makes Graph Foundation So Different?

Graph Foundation is a not for profit corporation that does not provide commercial licensing for any graph technology managed and maintained by it. This prevents mis-aligned objectives commonly encountered by for profit corporations that must pursue revenue objectives above all else. Graph Foundation is governed and guided by the graph community in order to provide everyone with fully free and open source graph software. The graph community is a global, diverse and connected group. The Graph Foundation hopes to provide the opportunity for effective coordination, collaboration and unification for the graph community around its most important projects, such as ONgDB. To all the valued members of the community, thank you.
