The technology is interesting but the billing doesn't convince me. I don't feel that I can scale storage easier with Neon than using just a bigger server with plain Postgresql.
Neon is more than just Postgres with a storage device. It's a managed service with features like branching, autoscaling, bottomless storage, etc.
People who really find Neon valuable usually partake in our "differentiating" features, so if all you need is a managed Postgres, there will definitely be more competitive prices out on the market.
