Build system that turns a source directory into an OCI image, now in maintenance mode

The short version
- Only Nixpacks has a free tier, so it costs nothing to try first.
- Each has a real cost: Fenergo implementations commonly run twelve to twenty-four months and depend on a systems integrator, so the services cost frequently exceeds the software subscription in year one.; 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: Fenergo covers Regulatory rules library, Nixpacks covers Automatic language detection.
- Prices and features above were last checked on 1 September 2026.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Fenergo
- Implementations commonly run twelve to twenty-four months and depend on a systems integrator, so the services cost frequently exceeds the software subscription in year one.
- It orchestrates screening but does not supply the sanctions, PEP or adverse media data, so you still buy Dow Jones, LexisNexis or World-Check separately and those fees are per screened entity.
- The entry price is set for institutions with large onboarding volumes, which puts it out of reach of smaller banks and fintechs that would otherwise benefit from the rules library.
- Configuration is deep and specific, which makes upgrades between major versions a project rather than a patch, and some customers stay on old releases for years.
- The rules library covers regulatory requirements, not your internal risk appetite, so the policy tuning that determines whether onboarding actually gets faster remains your work.
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.

Questions people ask
- Is Fenergo or Nixpacks better?
- Neither clearly leads. Fenergo starts at On request and Nixpacks at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Fenergo or Nixpacks?
- Nixpacks has a free tier; the other does not. Paid plans start at On request for Fenergo and Free for Nixpacks.
- Does Fenergo or Nixpacks run on more platforms?
- Fenergo runs on Web. Nixpacks runs on Linux, macOS, CLI, Docker.
- Can I use Nixpacks for free?
- Yes. Nixpacks has a free tier, so you can try it without paying. Fenergo starts at On request.
- What is Fenergo best used for?
- Fenergo is most often used for a bank operating in twenty jurisdictions that cannot keep local kyc requirements current across separate regional teams, a custodian moving from calendar-based periodic review to event-driven perpetual kyc to cut analyst headcount, an asset manager onboarding funds and trusts where the ownership hierarchy defeats generic identity verification tools, a payments institution facing a regulatory remediation order and needing a defensible audit trail of every client review. Of those, a bank operating in twenty jurisdictions that cannot keep local kyc requirements current across separate regional teams and a custodian moving from calendar-based periodic review to event-driven perpetual kyc to cut analyst headcount are not what Nixpacks is typically brought in for.
- What can Fenergo do that Nixpacks cannot?
- Fenergo covers Regulatory rules library, Digital onboarding, Perpetual KYC, Entity data model. Nixpacks covers Automatic language detection, No Dockerfile required, Nix toolchains, Configuration escape hatches.
Answered from the vendors’ own pages
Fenergo: Does Fenergo do the sanctions screening itself?
No. It orchestrates calls to third-party data providers such as Dow Jones and World-Check, and those subscriptions are additional and usually charged per screened entity.
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.
Fenergo: Is it SaaS or on-premises?
Both. The SaaS offering runs on Microsoft Azure with regional deployment options, which matters where data residency rules prohibit client data leaving the jurisdiction.
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.
Fenergo: How long does a deployment take?
Plan for a year at minimum for a multi-jurisdiction rollout. Single-jurisdiction deployments with a narrow product set can be shorter but rarely under six months.
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.
