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.; Wiz no public pricing; licensing requires a custom quote based on workloads and sensors.
  • They diverge on capability: Nixpacks covers Automatic language detection, Wiz covers Cloud security posture management.
  • 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.

Wiz

  • No public pricing; licensing requires a custom quote based on workloads and sensors.
  • Modular licensing across Cloud, Code, Defend, and Sensor products can complicate cost planning.
  • Full runtime protection value depends on deploying Wiz Sensor agents, adding operational overhead.
  • Primarily aimed at mid-to-large enterprises despite the smaller Wiz Go bundle.

Questions people ask

Is Nixpacks or Wiz better?
Neither clearly leads. Nixpacks starts at Free and Wiz at On request, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
Which is cheaper, Nixpacks or Wiz?
Nixpacks has a free tier; the other does not. Paid plans start at Free for Nixpacks and On request for Wiz.
Does Nixpacks or Wiz run on more platforms?
Nixpacks runs on Linux, macOS, CLI, Docker. Wiz runs on web, api.
Can I use Nixpacks for free?
Yes. Nixpacks has a free tier, so you can try it without paying. Wiz starts at On request.
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 Wiz is typically brought in for.
What can Nixpacks do that Wiz cannot?
Nixpacks covers Automatic language detection, No Dockerfile required, Nix toolchains, Configuration escape hatches. Wiz covers Cloud security posture management, Code security (Wiz Code), Runtime threat detection (Wiz Defend), AI security agents.

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.

Wiz: How much does Wiz cost?

Wiz does not publish standard pricing. The platform uses modular licensing based on workloads, active developers, log ingestion, or sensors. All pricing requires requesting a custom quote directly from the company.

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.

Wiz: Does Wiz offer a free trial?

No free trial information is mentioned on Wiz's pricing page. Pricing is determined by custom quote based on organizational needs.

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.

Wiz: What products does Wiz offer?

Wiz provides five modular licensing options: Wiz Cloud, Wiz Code, Wiz Defend, Wiz Sensor, and Wiz Go Bundle for SMBs, allowing organizations to scale based on specific security requirements.

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.
