The short version

  • Each has a real cost: Chainguard containers Catalog at 19,000 USD/year expensive for teams under 10 people; Skaffold the skaffold.yaml apiVersion changes with releases and old configs stop being accepted, so upgrading is not a no-op; you run skaffold fix and re-test your profiles.
  • They diverge on capability: Chainguard covers Hardened container images, Skaffold covers Dev loop.
  • 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.

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

Skaffold

  • The skaffold.yaml apiVersion changes with releases and old configs stop being accepted, so upgrading is not a no-op; you run skaffold fix and re-test your profiles.
  • It is a Google project outside CNCF governance, and the Google Cloud Build and Cloud Deploy integrations are noticeably better developed than anything for AWS or Azure, which shapes the tool toward one cloud.
  • File sync only helps when the runtime picks up changed files without a restart; for compiled languages you are back to a full image rebuild each save and the headline speed advantage largely disappears.
  • It solves the inner loop and stops there. There is no approval workflow, no environment promotion and no audit trail, so you still need a separate delivery tool and now maintain two definitions of how deployment works.
  • Debugging a failing Skaffold run means understanding your builder, your deployer, your cluster and Skaffold's own layering all at once, and its error output often surfaces the underlying tool's message without saying which stage produced it.

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
Skaffold: Is Skaffold a continuous delivery system?

No. It automates build and deploy for developers and CI, but it has no promotion, approval or rollback governance. Pair it with Argo CD or Cloud Deploy for that.

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
Skaffold: Does Skaffold require Google Cloud?

No, it works against any Kubernetes cluster including local kind or minikube. Google Cloud integrations are optional but are the best-supported ones.

Chainguard: Can I try Chainguard before purchasing?

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

Source
Skaffold: Is the project still maintained?

Yes. Releases continued through 2026, with v2.24.0 published in July 2026.

Skaffold: Can it deploy Helm charts?

Yes, Helm is a first-class deployer alongside kubectl, Kustomize and kpt, and you can mix builders and deployers in one config.
