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.; Surfshark smaller server network (4,500+ servers) compared to larger competitors like NordVPN
  • They diverge on capability: Nixpacks covers Automatic language detection, Surfshark covers Unlimited devices.
  • 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.

Surfshark

  • Smaller server network (4,500+ servers) compared to larger competitors like NordVPN
  • Lower brand recognition compared to established VPN providers
  • Limited customer service availability in some time zones

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.

Surfshark: Does Surfshark maintain a no-logs policy?

Yes. Surfshark does not log browsing history, visited IP addresses, bandwidth usage, or network traffic. This policy was independently verified by Deloitte in 2025.

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.

Surfshark: How many simultaneous device connections does Surfshark allow?

Surfshark allows unlimited simultaneous connections on all subscription plans, enabling protection of every device in a household with a single subscription.

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.
