The short version

  • Each has a real cost: Earthly pricing model not published; requires sales contact; 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: Earthly covers Policy as code, Skaffold covers Dev loop.
  • Prices and features above were last checked on 31 August 2026.

What people use each for

The jobs each tool is most often brought in to do.

Earthly

  • Enforcing engineering standards across AI and human developersnot Skaffold
  • Automating incident response procedures across all repositoriesnot Skaffold
  • Embedding compliance requirements into development workflowsnot Skaffold
  • Standardizing build processes with Earthfilesnot Skaffold

Skaffold

  • A microservices team whose application cannot be run meaningfully outside a cluster and needs a fast local edit-to-running cyclenot Earthly
  • Standardising build and deploy commands across many repositories so onboarding is one command rather than a wiki pagenot Earthly
  • Producing rendered manifests in CI for a GitOps controller such as Argo CD to applynot Earthly
  • Giving developers on underpowered laptops a remote build path via Cloud Build while keeping the same local workflownot Earthly

Where each one falls short

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

Earthly

  • Pricing model not published; requires sales contact
  • Earthly Lunar is a recent launch (2025) with limited track record
  • Primarily GitHub-focused; limited integration with other platforms
  • No public documentation on pricing or feature tiers

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

Earthly: What is the difference between Earthfiles and Earthly Lunar?

Earthfiles is an open-source build tool that reached 12,000 GitHub stars and is used by companies like NVIDIA, Intel, and Databricks. Earthly Lunar is a separate governance platform launched in 2025 for enforcing standards across development workflows.

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.

Earthly: How does Earthly Lunar enforce standards?

Lunar converts engineering standards, compliance requirements, and processes documented in AGENTS.md files, wikis, and incident postmortems into enforceable guardrails that apply consistently across repositories and development stages.

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.

Earthly: What is the pricing for Earthly Lunar?

Pricing is not published on the website. Interested customers should contact Earthly's sales team for current pricing and feature tiers.

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.
