Vercel Postgres

Serverless PostgreSQL database service built for the Vercel platform, offering zero-config relational storage directly wired to deployments. Credentials and connection strings were injected as environment variables, and the @vercel/postgres SDK provided an edge-compatible client with pooled and direct connections.

Vercel Postgres databases were automatically migrated to Neon in December 2024. Users now provision Postgres through the Vercel Marketplace, with Neon as the default integration. Existing ORMs and tools such as Drizzle, Prisma, and Kysely continue to work; the SDK remains compatible but is no longer actively maintained by Vercel, with Neon offering drop-in and migration paths.

Key features:

• Zero-config setup with environment variables auto-injected into Vercel projects
• Edge-ready client supporting serverless and Edge Runtime workloads
• Pooled and direct connection modes via createPool and createClient
• Tagged template literals for parameterized queries
• Compatibility with popular ORMs: Drizzle, Prisma, Kysely

Use cases: Relational data for Next.js and other Vercel-deployed apps, user data and app state, transactional workloads on serverless and edge. Developers could attach a Postgres store from the Vercel dashboard and run queries via tagged template literals without managing servers or connection lifecycle.
