The verdict
If you sell internationally and want coaching and downloads next to your courses, I'd pick Teachable. If you sell cohorts, run a community, or sell training to companies, pick Thinkific. Neither is the cheap option once you need the extras. Teachable's entry plan carries a transaction fee, and its API and webhooks need the Growth plan, with the MCP server in early access. Thinkific starts memberships and cohorts on its second plan, and branding removal, B2B sales and API access on its third. Buy for what you will need in a year, not on day one.
