Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Nixpacks

  • The project is in maintenance mode with no commits on the default branch since May 2026 and no release since October 2025, so support for new language versions arrives only if someone forks it
  • Build determinism is softer than it appears, because providers pin a nixpkgs archive commit and bumping that archive silently moves compiler and runtime versions underneath a build that looks unchanged
  • Caching is limited to Docker layers rather than a content addressed graph, so a small change early in the build invalidates everything after it, which is exactly the limitation Railpack was rewritten to fix
  • Images carry Nix store layers and come out larger than an equivalent tuned Dockerfile or buildpack output, which costs registry storage and slows cold pulls on scale-out
  • There is no specification, no vendor neutral governance and no third party provider ecosystem, so a single company was able to redirect strategy and leave every downstream user with a frozen build tool

Procreate

  • iPad-only application with no desktop version for Windows or macOS
  • Requires Apple hardware investment (iPad and Apple Pencil)
  • Cannot export to cloud storage natively, limiting cross-device workflows
  • High upfront cost when accounting for required iPad hardware

Answered from the vendors’ own pages

Nixpacks: Should I start a new project on Nixpacks?

No. The documentation and README both say it is in maintenance mode and recommend Railpack. Choose Railpack, Cloud Native Buildpacks or a Dockerfile instead.

Procreate: Does Procreate work on desktop or only iPad?

Procreate is iPad-only. There is no desktop version for Windows or macOS, requiring users to purchase iPad hardware and Apple Pencil for use.

Source
Nixpacks: Will my existing Nixpacks builds stop working?

Not immediately. Pinned nixpkgs archives keep resolving, so builds continue. What you lose is support for new runtime major versions and any fix for a provider bug.

Procreate: What companion apps are available for Procreate?

Procreate Pocket is an iPhone version at $5.99, and Procreate Dreams is an animation tool at $19.99, both one-time purchases.

Source
Nixpacks: What replaces it?

Railpack, also from Railway and also MIT licensed, rebuilt as a BuildKit custom frontend for finer grained caching and parallel steps.

Nixpacks: Is it still open source?

Yes, MIT, and the repository is not archived. Being open source does not help much when nobody is merging provider updates.
