The verdict
If the course is the business and you want to own the look and the learner experience, I'd pick LearnWorlds. If you want to sell courses, coaching and downloads internationally and have payment and tax handled for you, pick Teachable. Both put limits behind plans. LearnWorlds charges a fee on each paid enrolment on its entry plan, and API access and webhooks sit on the third plan and above. Teachable's entry plan carries a transaction fee, and its API and webhooks need the Growth plan. Its MCP server is in early access. Work out which limits hit you before you pay.
