It seems most of the concerns in this thread are related to devops which is not something Remix influences.
Remix is about making the front-end “use the platform”, progressive enhancement, SSR etc. They really strip things back to basics and it’s taking me back 20 years. I love it, and I can still write React.
Keep an eye because they have some interesting news to announce these coming weeks. I don’t work for them, just an early adopter.
