Start with what you are actually selling, not the ranking. A solo creator launching one course, a coach building a paid community, and an HR team training staff need genuinely different tools. The best overall platform is rarely the best for your specific job, so use the category lists below to get closer.
Watch the fees, not just the monthly price. A "cheap" plan that skims a percentage off every sale can cost far more than a pricier plan with zero transaction fees once you are selling at volume. Work out the real cost at your expected revenue before you decide.
Build a test course before you commit. Most platforms offer a free plan or trial, and an hour spent uploading a lesson, setting a price and previewing the student view tells you more than any feature list. The course builder you find quick and obvious is the one you will actually keep using.
Decide whether you want all-in-one or best-of-breed. Kajabi and Podia bundle email, funnels and a website with your courses; Thinkific and Teachable focus on the course and let you bring your own marketing stack. One subscription is simpler; separate tools are often more powerful.
Think about switching cost early. Your courses, members and sales pages do not move cleanly between platforms, so the one you pick is sticky. Favour a tool you can grow into over one you will outgrow in six months.
