Vercel Postgres is a managed PostgreSQL database service integrated into Vercel's serverless platform. It handles connection pooling, automatic scaling, backups, and failover without operational overhead. Developers connect via simple connection strings and query from serverless functions, edge functions, or cron jobs. Vercel Postgres solves a critical problem: traditional databases become bottlenecks in serverless architectures because they aren't designed for thousands of short-lived connections. Vercel Postgres includes built-in connection pooling, making it ideal for serverless applications that need reliable, fast database access without ops burden.
