## Serverless Postgres Providers

The fastest-growing category of RDS alternatives is serverless Postgres: [Neon](https://neon.com/) (acquired by Databricks), [Supabase](https://supabase.com/), [PlanetScale Postgres](https://planetscale.com/), and [Prisma Postgres](https://www.prisma.io/postgres). They separate storage from compute, scale to zero when idle, and start free or nearly free, which makes them a compelling swap for the many RDS instances that sit mostly idle. The trade-offs are engine coverage (Postgres only) and less knob-level control than RDS. We compare their pricing in depth in [PostgreSQL Hosting Options: Pricing Comparison](/blog/postgres-hosting-options-pricing-comparison/).

## Cost Comparison (us-east-1)

To provide a clear comparison of database costs across different providers, below is pricing information for various RDS alternatives in the us-east-1 region (or equivalent). This comparison focuses on PostgreSQL offerings with similar specifications to enable direct comparison.
