Quick Verdict
Choose PostgreSQL if you need a powerful, free, and self-managed relational database for complex applications. Choose PlanetScale if you prioritize a serverless, highly scalable MySQL platform with a Git-like workflow for modern web apps and are willing to pay for managed operations.
PostgreSQL is a mature, open-source object-relational database system you can run anywhere, offering unparalleled features, extensions, and SQL compliance. PlanetScale is a commercial, serverless platform that layers a developer workflow and horizontal scaling atop MySQL compatibility via Vitess. Their core difference is PostgreSQL's self-managed, feature-rich flexibility versus PlanetScale's managed, workflow-driven scalability. PostgreSQL targets engineers who value control and advanced features, while PlanetScale targets teams wanting a frictionless, scalable database-as-a-service.
