The short version

  • Only Nixpacks has a free tier, so it costs nothing to try first.
  • Each has a real cost: Contabo fully unmanaged infrastructure requires all setup and maintenance by customer; 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.
  • They diverge on capability: Contabo covers VPS Hosting, Nixpacks covers Automatic language detection.
  • 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.

Contabo

  • Fully unmanaged infrastructure requires all setup and maintenance by customer
  • No formal SLA with financial compensation for downtime violations

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.

Answered from the vendors’ own pages

Contabo: What is the base pricing for Contabo VPS?

Contabo Cloud VPS starts at EUR 4.50 per month (approximately $4.95 USD) with 4 vCPU cores and 8 GB RAM. Prices scale up to EUR 39+ per month for dedicated performance VPS with higher specs.

Source
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.

Contabo: Does Contabo raise prices at renewal?

No. Unlike many hosting providers, Contabo does not increase renewal prices. The promotional price you get at sign-up is locked in for future renewals.

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.

Contabo: What data center locations does Contabo offer?

Contabo operates 9 global data center regions including multiple EU locations, US East/Central/West Coast, United Kingdom, India, Singapore, Japan, and Australia.

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.

Contabo: Does Contabo provide managed services?

No. Contabo VPS is fully unmanaged. You handle all setup, security patching, and system maintenance. Managed hosting adds 2 hours per month of dedicated support for a fee.

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.

Contabo: What is Contabo's uptime guarantee?

Contabo maintains a 99.996% uptime guarantee across all plans. The platform includes unlimited traffic and free DDoS protection.
