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.; ProtonVPN free plan limited to one device at a time
- They diverge on capability: Nixpacks covers Automatic language detection, ProtonVPN covers No-logs policy.
- 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.

- You want to start without paying.
- You work on Linux, macOS, CLI, Docker.
- You also want no dockerfile required.

Questions people ask
- Is Nixpacks or ProtonVPN better?
- Neither clearly leads. Nixpacks starts at Free and ProtonVPN at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Nixpacks or ProtonVPN?
- Nixpacks starts at Free and ProtonVPN at Free.
- Does Nixpacks or ProtonVPN run on more platforms?
- Nixpacks runs on Linux, macOS, CLI, Docker. ProtonVPN runs on Windows, macOS, Linux, iOS, Android.
- Can I use Nixpacks for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Nixpacks best used for?
- Nixpacks is most often used for understanding the build behaviour of a platform that adopted nixpacks before it was frozen, producing container images from a polyglot monorepo where nobody wants to own several dockerfiles, reproducing an existing railway build locally while planning a migration to railpack, comparing what a nix based builder does differently from a buildpack before choosing a successor. Of those, understanding the build behaviour of a platform that adopted nixpacks before it was frozen and producing container images from a polyglot monorepo where nobody wants to own several dockerfiles are not what ProtonVPN is typically brought in for.
- What can Nixpacks do that ProtonVPN cannot?
- Nixpacks covers Automatic language detection, No Dockerfile required, Nix toolchains, Configuration escape hatches. ProtonVPN covers No-logs policy, Secure Core, Kill Switch, DNS leak protection.
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.
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.
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.
