The short version

  • Each has a real cost: Chainguard containers Catalog at 19,000 USD/year expensive for teams under 10 people; Cloud Native Buildpacks the operational cost is real: you own builder images, base image refresh cadence and migrations between specification versions, which currently sit at Buildpack API 0.10 and Platform API 0.12 with published migration guides, so breaking changes are a recurring chore.
  • They diverge on capability: Chainguard covers Hardened container images, Cloud Native Buildpacks covers Detect and build lifecycle.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

Cloud Native Buildpacks

  • Patching a base image once and rebasing hundreds of application images rather than rebuilding and redeploying eachnot Chainguard
  • Removing per-team Dockerfiles at an organisation where inconsistent base images have become an audit findingnot Chainguard
  • Giving application teams a supported path to a hardened image without teaching every team container securitynot Chainguard
  • Choosing a build system that a risk committee will accept because governance is vendor neutral rather than single vendornot Chainguard

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Chainguard

  • Containers Catalog at 19,000 USD/year expensive for teams under 10 people
  • Per-image pricing for containers requires custom quotes with no transparency
  • Free tier limited to 5 container images for testing
  • Libraries pricing by ecosystem and developer count lacks transparent per-developer cost
  • VM image catalog pricing opacity makes cost estimation difficult

Cloud Native Buildpacks

  • The operational cost is real: you own builder images, base image refresh cadence and migrations between specification versions, which currently sit at Buildpack API 0.10 and Platform API 0.12 with published migration guides, so breaking changes are a recurring chore.
  • A cold build with no warm cache is noticeably slower than a well layered Dockerfile, and because the cache lives in a cache image or volume, ephemeral continuous integration runners pay full price on every run unless you deliberately warm them.
  • Reproducibility depends on discipline rather than defaults, because buildpacks resolve runtime patch versions at build time unless you pin them and stability is only as good as the builder image tag you point at.
  • The specification is neutral but the buildpacks are not, and in practice you depend on Paketo, Heroku or Google, whose roadmaps, support levels and update cadences differ; CNCF also records contributing organisations down 12 per cent year on year.
  • Native dependencies, unusual monorepo layouts and non-standard project structures push you into writing custom buildpacks or extensions, which is a genuine engineering investment and not a configuration change.

Answered from the vendors’ own pages

Chainguard: How much is the Chainguard Containers Catalog?

The Containers Catalog is 19,000 USD per year for 10-person engineering teams, providing access to 2,000+ hardened container images.

Source
Cloud Native Buildpacks: What does CNCF graduation actually change?

Nothing technically, but it signals audited governance, security review and multi-vendor maintenance, which is usually what a procurement or risk team needs before approving a build system.

Chainguard: What SLAs does Chainguard offer?

Chainguard provides contractual CVE remediation SLAs: 7 days for critical vulnerabilities, 14 days for high/medium/low severity, all with priority support.

Source
Cloud Native Buildpacks: How is this different from writing a Dockerfile?

Container build knowledge lives with the platform team in a builder image rather than in every repository, and rebasing lets you patch the runtime base of many images without rebuilding them.

Chainguard: Can I try Chainguard before purchasing?

Yes. The free tier includes five container images for testing and deployment, allowing hands-on evaluation.

Source
Cloud Native Buildpacks: Does it cost anything?

No. The specification and tooling are Apache-2.0 and free. You pay only if you buy commercial support for a specific buildpack distribution from Broadcom, Heroku or Google.

Cloud Native Buildpacks: Is it slower than a Dockerfile?

On a cold build with no cache, yes. Warm builds are competitive, but continuous integration runners that start empty every time will feel the difference.
