Coolify has emerged as a premier self-hosted alternative to Vercel and Netlify. While its default Nixpacks builder is excellent for zero-configuration deployments, developers often require granular control over the build environment.

This guide demonstrates how to deploy a Next.js application on Coolify v4 (specifically tested on v4.0.0-beta.460) using a multi-stage Dockerfile. This method ensures a highly optimized, production-ready image.
