We rolled Moodle out across our entire university and it has handled thousands of students without breaking a sweat. The fact that it's open-source means our IT team could customise the gradebook and quiz engine exactly the way our faculty wanted. The plugin ecosystem is enormous and we found tools for almost everything.
Free, flexible, huge plugin library
We've run Moodle for three years and it has been reliable for delivering courses and tracking grades. My only gripe is that you really need a competent server admin to keep it updated and fast, otherwise pages start to lag. For institutions with the technical skills, it's hard to beat.
Reliable and feature-rich
Needs technical maintenance
As a school running on a tight budget, Moodle being free and self-hosted was a lifesaver. The activity completion tracking and conditional release of content let us build proper learning paths for each cohort. Community support forums answered every question we had during setup.
Zero cost, self-hosted, active community
Moodle does everything you could want from a learning management system, but the admin interface feels dated and unintuitive. Teachers on our staff struggled for weeks before they got comfortable building courses. Once you know it, it's brilliant, but getting there takes patience and decent IT support.
Very capable once mastered
Steep learning curve, dated UI
Moodle has let us deliver staff training and certifications without paying per-seat fees that commercial platforms charge. The quiz and SCORM support is excellent. The mobile app could be smoother, but overall we're very happy with what we get for an open-source tool.
Cost-effective, strong assessment tools
Mobile app a little clunky
