MIT and Harvard, the creators of edX.org, released the software behind the educational portal as open-source in June of 2013.
Consequently, skilled developers have been able to build fully brandable and customizable Open edX platforms.
Code contributions are received every day, and innovation is non-stop.
The latest Open edX release is called “Dogwood”. The three previous releases were “Aspen” (October 2014) and “Birch” (March 2015) and “Cypress” (July 2016). The next Open edX release, Eucalyptus, is expected for the end of July 2016.
A full list of features is posted here.
Open edX’s codebase is available under an AGPL license (except for XBlocks, which are under Apache 2.0, allowing you to create closed-source solutions). These two licenses allow you to build a commercial offer. Keep in mind, however, that according to the terms of the AGPL license, if you make any modifications to the codebase, you must release them. In other words, if you build new features or alter existing ones, you must make your changes freely available for other developers to see and use.
As a not-for-profit enterprise composed of leading universities, the xConsortium — which is behind edX.org and the Open edX software — is committed to an open-source vision.
Along with MIT and Harvard University, significant contributors to the Open edX initiative include Google, Stanford, UC Berkeley, McKinsey Academy, the University of Queensland, Tsinghua University and IBL-George Washington University.
