Our Verdict
PostgreSQL is the best general-purpose database handling relational, JSON, and basic graph queries (via Apache AGE). Neo4j is the specialized graph database with native graph storage and the Cypher query language. Choose PostgreSQL for most applications, Neo4j when relationship traversal is the primary workload.
💡 This verdict is based on general use cases. Your specific requirements, existing tech stack, and team expertise should guide your final decision.
Frequently Asked Questions
Can PostgreSQL do graph queries?
Yes, with the Apache AGE extension, PostgreSQL supports Cypher graph queries. However, performance for deep traversals (3+ hops) is significantly slower than Neo4j's native graph storage with index-free adjacency.
When should I use Neo4j instead of PostgreSQL?
Use Neo4j when your queries primarily involve traversing relationships — fraud detection, recommendation engines, knowledge graphs, network analysis. If relationships are secondary to your data model, PostgreSQL handles basic graph queries adequately.
Is Neo4j free?
Neo4j Community Edition is free (GPL). AuraDB Free provides a cloud instance with 200K nodes. Enterprise Edition requires a paid license (~$36K+/year).
