OpenCraft and edX are different companies, but we work closely together on the Open edX platform. The Open edX platform is the software platform which runs edx.org. edX open sourced the project in 2013, and OpenCraft’s founder, Xavier, was the first outside contributor to the project. To understand more about the relationship between edX and the Open edX platform, as well as get an overview of the platform, watch this video. OpenCraft is an Open edX Partner, and we are the largest outside contributor to the Open edX platform. We specialize in custom solutions for various clients— especially those who require carefully planned architecture or scaling— while edX focuses on improving Open edX for the edX.org website. We also offer a SaaS platform that lets customers try their own copy of the Open edX platform. OpenCraft is frequently contracted by edX to add major features to the platform. We also coordinate the creation of new features between our clients, edX, and the Open edX community at large. We are confident in saying that outside of edX themselves, we are the foremost experts in the Open edX platform.
