Building a SaaS app (probably Node + React). Confused about DB choice.

MongoDB seems easier to start with but Postgres is more robust? My app has users, orders, subscriptions – typical stuff.

What did you choose for your project?

Building SaaS – use PostgreSQL.

Yes Mongo is easier to start but Postgres handles complex queries way better. Need to do reporting/analytics later? Postgres wins.

Prisma + Postgres is a great combo in 2026. Very mature ecosystem.
