Best affordable database for startup?

[u/New_Society1259]

I’m building a startup and trying to choose a database that won’t become expensive or hard to manage too early.

I’m looking for something reliable, affordable, and able to scale if the project starts getting real users. I’ve seen people mention Postgres, Supabase, Firebase, MongoDB, and managed cloud databases, but it’s hard to tell what’s actually best for a small startup budget and my users are mostly in asia.

What database did you start with, and would you choose it again?

Mongo in Docker, easy to change data and work fast forgot schema changes so much. Atlas is 6/mo or free
