Nixpacks — App Source to Docker Image

Overview

Nixpacks, the build system created by Railway that automatically detects your application's language and framework, installs dependencies, and produces optimized Docker images — all without writing a Dockerfile. Helps developers configure Nixpacks for custom build steps, multi-language projects, and CI/CD integration.
