Open edX platform is the open-source platform software developed by edX and made freely available to other institutions of higher learning that want to make similar offerings. On June 1, 2013, edX open sourced its entire platform.[20] The source code can be found on GitHub.[21][22] The Open edX server-side software is almost entirely based on "Python, with Django as the web application framework."[23] https://en.wikipedia.org/wiki/EdX#Open_edX_Platform
