NextJS as a framework is pretty good, it has gone downhill since the whole RSC shift sure but its still pretty good for most use cases. The problem however is Vercel and how closely its tied to Vercel.

I recently developed a small internal application in NextJS and we are using Azure PostgreSQL, we are on the Pro Plan from Vercel (honestly even that's an overkill, our use case would be satisfied easily on the free plan; which is very very generous) but one problem I faced is a NextJS App hosted on Vercel, it will never have a static fixed IP, so we couldn't directly access our database unless ofc we opened it to the entire world, which is never an option. This is so dumb honestly, the audacity to call it a full stack framework is stunning.
