Recommendations for publishing and selling courses online?

Hi all,

As part of my business, I'd like to publish and sell some courses online. Ideally, it would look uniquely branded and be at my domain name (so I'd prefer not to publish through a platform like Udemy, for example). I am a software developer but ideally I wouldn't have to do much of any coding on the learning system itself--the course content is the product. That being said, I'm happy to self-host good open source software if it's out there.

Do folks have recommendations for websites or open source software that check these boxes?
