Vercel

Vercel now supports automatic detection and deployment of Elysia, a TypeScript framework with end-to-end type safety. When deployed, Vercel automatically provisions optimal resources and uses Node by default, with optional Bun runtime support via configuration. Deployments leverage Fluid compute with Active CPU pricing, charging only for active CPU usage time.
