The short version

  • Each has a real cost: 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.; Penpot smaller user base and community compared to Figma means fewer templates and resources
  • They diverge on capability: Nixpacks covers Automatic language detection, Penpot covers Vector editing.
  • Prices and features above were last checked on 31 August 2026.

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.

Penpot

  • Smaller user base and community compared to Figma means fewer templates and resources
  • Self-hosting requires Linux server and Docker knowledge for technical setup
  • Real-time collaboration features may have performance issues with very large design files

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.

Penpot: Is Penpot really free?

Yes. Penpot is completely free with no feature gates. The open-source version can be self-hosted on your own infrastructure for zero cost beyond server expenses.

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.

Penpot: Can I self-host Penpot?

Yes. Penpot can be self-hosted on your own infrastructure with no licensing costs. Organizations with specific privacy or governance needs can run Penpot on their own servers.

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.

Penpot: What are the paid plans if I use Penpot cloud?

Penpot's cloud service offers a free tier, Unlimited plan at $7 per user per month for professionals and medium teams, and Enterprise starting at $950 per month for larger organizations.

Source
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.

Penpot: What platforms does Penpot support?

Penpot runs in the browser, so it works on Windows, Mac, Linux, and any OS with a web browser. No platform-specific downloads required.
