LearnDash

LearnDash is a free WordPress LMS plugin available directly from WordPress.org with no licensing costs. It offers full course creation, quizzes, progress tracking, and drip-feed content to control when students access lessons. Since 2014, it's been the go-to choice for WordPress users who want professional course functionality without paying for SaaS.

Best for WordPress users comfortable with plugin management and self-hosting. Compared to cloud platforms, you own your data completely and have full control over your site, though you handle your own hosting, backups, and security updates.
