PostgreSQL vs MongoDB: Which Is Right for You?
PostgreSQL is our default database — it handles relational data, JSON, full-text search, and geospatial queries in one system. MongoDB's flexible document model is useful for specific use cases but is not a general improvement.
Our Verdict
PostgreSQL is our default for every project. It handles 95% of use cases better than MongoDB while providing ACID guarantees that protect your users' data. MongoDB makes sense for specific document-storage use cases — not as a default database choice.
PostgreSQL vs MongoDB: At a Glance
PostgreSQL wins when…
- ✓ ACID transactions that keep your data consistent — critical for financial and business applications

- ✓ JSONB support means you get document flexibility alongside relational integrity
- ✓ Mature ecosystem with Prisma and Drizzle providing excellent TypeScript ORM support
MongoDB wins when…
- ✓ MongoDB's document model fits naturally for deeply nested, schema-less data structures
- ✓ MongoDB is often faster to prototype with when your schema is genuinely uncertain
