6 Best Serverless SQL Databases for Developers (2026 Comparison)

Serverless SQL databases separate compute from storage, allowing databases to scale to zero when idle. Neon offers database branching for Postgres workflows, Supabase provides a full backend stack with auth and storage, Turso delivers edge-speed SQLite replication, PlanetScale handles massive scale with zero-downtime schema changes, TiDB Cloud manages spiky traffic with distributed MySQL, and Prisma Postgres optimizes for Prisma ORM users with instant cold starts. The choice depends on your SQL flavor preference, latency requirements, and whether you need features like branching or full backend services.
