Vercel supports running any HTTP server directly from a Dockerfile, enabling deployment of applications built with frameworks like Rails, Django, Spring Boot, and Go. This feature leverages Fluid compute for autoscaling and active CPU pricing, with optimized boot images for fast startup. Containers are treated as first-class citizens, integrating with the Vercel platform for builds, storage, deployment, and observability.
