Neo4j
- Best-in-class graph model and Cypher
- Great for knowledge graphs and recommendations
- Aura managed option plus self-host
- Not a drop-in SQL/RDBMS replacement
- Graph modeling mindset required
- Cost can rise for large Aura workloads
PostgreSQL
- Gold-standard open-source SQL engine
- Huge extension ecosystem (including vectors)
- Foundation for many modern BaaS platforms
- You assemble auth/storage yourself
- Ops complexity grows without a managed host
- Not a serverless product by itself
