Opigno

Opigno is a Drupal-based learning management system built on free and open-source software, giving you full control over your installation and data. It includes H5P integration for creating interactive content, SCORM compliance for course portability, and community-building features like forums and user profiles. The platform supports certifications and completion tracking across cohorts.

This works best for organizations comfortable with Drupal's ecosystem who want maximum customization and data ownership. It's a strong choice for enterprises and non-profits looking to avoid licensing fees, though you'll need technical expertise to maintain the installation yourself.
