Moodle

Moodle is the world's most widely adopted open-source LMS powering learning in over 190 countries. For indie hackers with technical skills, Moodle is unlimited—zero license fees, unlimited courses, unlimited users, unlimited customization. The free software includes all core features (assignments, quizzes, forums, video SCORM support, detailed gradebooks, analytics, plugins). The catch: indie hackers must handle hosting, security patches, and maintenance themselves (or hire someone for $50-300/month).\n\nMoodle suits technical solo founders building complex learning platforms long-term. It's overkill for simple courses but unbeatable for control and scale. Self-hosting on cheap VPS ($5-20/month) makes total cost negligible. Ideal for indie hackers who code or can learn DevOps—you own everything forever with no vendor lock-in.
