Teachable, Thinkific vs Udemy? Which is the Best Online Course Platform in 2025?

I have been researching a lot about how to create a successful online course since last year. I have yet to launch my video course but I have started with some Udemy practice courses like my Spring certification practice test course on Udemy which has more than 1500+ students so far. I chose Udemy because they have a great platform for practice tests, but I am also learning other platforms like Teachable and Thinkific to create an online course website that is fully owned by me. Along the way, I have also started mentoring many readers about creating online courses and why they should create them. Why I am doing this? because I believe together we can learn better and succeed. If I have a group of passionate developers who like to teach online, there is a better chance of creating a successful online course.
