edX (Open edX)
Modular learning management platform for online courses at scale

Open edX is an open-source online learning platform originating from edX, used to deliver MOOCs and structured online programs. It provides course authoring, learner-facing course delivery, assessments, and operational tools, and can be extended via plugins and integrations.
Key Features
- Web-based course authoring (Studio) and course delivery (LMS)
- Video-based learning experiences with sequencing and progress tracking
- Problem types and graded assessments (e.g., quizzes, assignments, exams) with configurable grading
- Discussion forums and course communication features
- User enrollment flows and course runs for repeated offerings
- Extensible architecture: pluggable components (e.g., XBlocks) and REST APIs for integrations
- Support for multiple sites/brands and theming in typical deployments
Use Cases
- Universities delivering large-scale online courses and professional certificates
- Enterprises running internal training programs with custom integrations
- Training providers offering cohorts, recurring course runs, and assessments
Limitations and Considerations
- Large, multi-service architecture can require significant operational expertise (deployment, upgrades, maintenance)
- Customization often involves plugins/theming and careful version compatibility across components
Open edX is best suited for organizations needing a robust, extensible learning platform with proven large-scale course delivery capabilities. Its modular ecosystem enables deep customization, while the platform’s breadth supports end-to-end online course operations.
