Neon has launched a new Data API that provides a PostgREST-compatible way to query Neon databases over HTTPS with JWT and RLS, offering per-branch endpoints. This API, re-implemented in Rust, integrates seamlessly into Neon's platform, allowing it to scale efficiently across multiple databases with a lighter CPU and memory footprint, making it suitable for large-scale, multi-tenant environments. Designed for developers and agents, the Data API simplifies backend setup by providing authentication, a REST API, and a Postgres database within a minute, supporting features like autoscaling, branching, and scale-to-zero. While PostgREST is a popular tool for turning databases into REST APIs, its compute-heavy nature presents challenges for large-scale operations, which the Neon Data API aims to address. With the ability to run as a shared service, the API reduces the need for fragmented processes and maintains consistent performance. Neon also supports integration with various authentication providers and offers a migration guide for those switching from Supabase. This latest addition to Neon's offerings aims to enhance the development of agent platforms by providing tools for quick backend deployment and efficient infrastructure management. Users of Neon RLS are advised to transition to the new Data API or use Postgres RLS directly, as Neon RLS will no longer be necessary with the new API's capabilities.
