Neon, a serverless database powered by Postgres, is transitioning its partnership with Vercel to provide all Neon features via the Vercel Marketplace. This change will give Vercel developers access to advanced features such as database branching, autoscaling, and improved security configurations while maintaining unified billing. The migration process will be executed in two steps: auto-migration of existing databases and allowing new databases to be created via Neon in the Vercel Marketplace. This collaboration aims to simplify platforms for developers as they build the next generation of applications.
