Side-by-Side Comparison
Objective metrics, no spin.
Web and mobile apps that want a full backend without building auth, storage, and APIs from scratch — especially strong for AI apps needing pgvector.
Complex enterprise workloads requiring fine-grained Postgres tuning — raw RDS or self-managed Postgres gives more control.
Apps with flexible, document-shaped data, or teams consolidating operational and AI (vector) workloads in one database.
Heavily relational workloads with strict joins and transactions — Postgres remains more appropriate.
