The edX learning platform has now completed its transition to open source and is available under an AGPL licence. The core of the system is the edx-platform which includes both the LMS (Learning Management System) and Studio, a tool for creating courses. Other parts of the system, such as the XBlock component architecture for courseware, machine-learning-based grading such as EASE, the discern tool, deployment tools, interfaces to external grading systems and Python execution utilities, can all be found on the new code.edx.org.
