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?

It depends on your data structure.

MongoDB: great for flexible schemas, rapid prototyping, document-heavy data (like user profiles with varying fields).

PostgreSQL: better for relational data, complex queries, transactions. More mature tooling.

For typical SaaS (users, orders, subscriptions) – Postgres. You wont regret it.

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.
