The Verdict
Duolingo is built for language learners and students, with a focus on lessons and stories. Moodle targets universities and schools and leads with course-management and quizzes.
Both tools come in at similar price points ($9.99/mo for Duolingo, $9.17/mo for Moodle), so pricing won't make the decision for you.
Both offer free plans, so you can test each with your real workflow before committing to a subscription.
Duolingo edges out on user ratings (4.6 vs 4). While both are well-regarded, that gap reflects real differences in user satisfaction worth considering.
Feature-wise, Duolingo 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: Duolingo has a slight overall edge — but if free and open-source matters most to you, Moodle may still be the right call.
