Assuming you’re talking about Supabase, I kind of disagree.

There’s an initial learning curve with the row level security stuff, but once you get a good grasp of it and come up with a few patterns that suit your needs it’s insanely fast to develop on. You’re trading the time it takes to build and manage an api for the time it takes to setup RLS.

I'd say Supabase is great at spinning up CRUD apps. If anything, this article could be summarized as "Because Val Town is much more than a CRUD app, they had a harder time with Supabase than the average."

https://github.com/t3-oss/create-t3-app hosted on Vercel + Planetscale / Railway DB is very easy, I would be surprised if you were miserable doing that.

Mostly that solves setting up Auth and Prisma SQL ORM to your DB, but Next.js App directory with the Prisma setup (2 files / 50 LOC) done is even smoother.
