Moodle is a powerful open-source LMS with broad education features and institutional flexibility. PrepOS is not trying to replace Moodle for universities. It is built for commercial STEM and test-prep businesses that need a premium branded offer, payments, qbanks, mocks, and faster launch/migration support.
