That's great. I didn't mean any discouragement as much as to say, I would probably not promote its self hosting ability as much. Promote that it's open source and keep working on it because I am sure you'll learn a lot about the field space. If it comes down to it that Heroku, Netlify, Vercel, and all other PaaS companies are gone, I will most likely just do a VPS or server just for my app than launch my own PaaS.

tl;dr if I am looking for a PaaS, I don't care that it's self hostable. I don't want to host it, that's why I am looking.
