The record

Purpose: Nixpacks takes a source directory and produces an OCI compliant image that can be deployed anywhere.
Maintenance status: The project is in maintenance mode, is not under active development, and recommends Railpack as a replacement.
Open source: Nixpacks was started by Railway and is open source on GitHub.
Build process: Nixpacks analyzes an app directory to create a reproducible build plan, then builds an OCI-compliant image using Docker BuildKit.
Automatic detection: Language providers are matched against the app source directory and suggest Nix packages and install, build, and start commands.
Customization: Users can override provider suggestions, add Nix or Apt packages, and customize build and start commands.
Language support: The documentation lists providers including Clojure, .NET, Deno, Elixir, Go, Java, Node, PHP, Python, Ruby, Rust, Swift, and Zig.
Caching: Providers cache directories during install and build phases by default, and users can change the cache key or disable caching.
Integrations: Nixpacks is available as a builder on Railway and has a GitHub Action for building containers and pushing them to a registry.
Installation platforms: Installation options include macOS through Homebrew or MacPorts, Windows through Scoop or MSI releases, and Debian or Ubuntu through .deb releases.
Runtime requirement: Building and running the output image uses Docker, and the documentation describes image creation with docker build.
Architecture limit: Nixpacks does not support building multiple architectures in one build; separate builds are required before creating a multi-architecture image.
Reproducible plans: A build plan can be saved and reused later to build the image with the same configuration.
