Pros & cons

MariaDB

  • MySQL-compatible with an open governance model
  • Strong for traditional SQL workloads
  • Self-host friendly with commercial options
  • Ecosystem mindshare still trails MySQL/Postgres
  • Not a turnkey BaaS
  • Serverless DX depends on your host

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
