The Verdict
Harbor is built for enterprise devops and container teams, with a focus on container-registry and vulnerability-scanning. Moodle targets universities and schools and leads with course-management and quizzes.
Harbor uses custom enterprise pricing, while Moodle starts at $9.17/mo — a tangible advantage for teams with a fixed budget.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Feature-wise, Harbor offers broader built-in capabilities (7 features vs 6), while Moodle takes a more focused approach — which can mean a simpler, faster onboarding experience.
Bottom line: Harbor has a slight overall edge — but if free and open-source matters most to you, Moodle may still be the right call.
