Pros & cons

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
