The short version

  • Only Nixpacks has a free tier, so it costs nothing to try first.
  • 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.; Sketch macOS-only for editing, blocking Windows and Linux users from accessing design features
  • They diverge on capability: Nixpacks covers Automatic language detection, Sketch 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.

Sketch

  • macOS-only for editing, blocking Windows and Linux users from accessing design features
  • Real-time collaboration feels less seamless than Figma with occasional sync delays
  • Limited built-in image editing capabilities, requiring external software for bitmap work
  • Subscription required for cloud features and collaboration, losing access if subscription lapses

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.

Sketch: Is Sketch available for Windows or Linux?

No. Sketch is macOS-only for the design and prototyping features. Web and mobile apps provide viewing and collaboration, but editing requires macOS 14.0 or later.

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.

Sketch: Does Sketch offer a free trial?

Yes. Sketch provides a 30-day free trial with no credit card required. You can also purchase a one-time Mac-only license for $120 per seat instead of subscribing.

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.

Sketch: What collaboration features does Sketch include?

Sketch supports real-time collaboration, unlimited document sharing, unlimited viewers, and version history on all paid subscription plans (Standard $12/month, Professional $24/month, Enterprise $44/month).

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.

Sketch: Can I use Sketch offline?

Yes. The one-time Mac-only license ($120) allows you to use Sketch offline and save files locally, but it excludes cloud collaboration and iOS previewing features.
