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
