I spent a week to realize that I don't need a trendy stack.
Like many, I started with Supabase as my database. Then I hit the free limits, the paid plans seemed greedy, and I decided to host everything on my own server. That took a week.
In return I got a system more complex than I needed, with limits that didn't suit me. I have other projects that need a database too, and Supabase has only one. It also turned out this beast eats a fair amount of resources.
In the end I just ran Postgres in containers on the same server as my other services, and I pay nothing extra for it.
I should have spent more time thinking than doing. Although I really wanted to try something new.
When you work alone, every wrong choice eats time, and there isn't much of it for experiments. The experience was useful, but I could have done without it.
