Moodle

Moodle has powered online learning for over two decades, trusted by millions of students across universities, K-12 schools, and corporate training programs worldwide. The open-source platform is completely free to download and self-host on your own server, with no licensing fees or vendor lock-in, and it's actively maintained by a global community of developers.

Pick Moodle when you need a feature-rich, battle-tested platform and you're comfortable managing your own hosting. Educational institutions especially favor it for its flexibility, accessibility compliance, and the ability to customize every aspect to fit institutional needs.
