Helm Kubernetes compatibility — check your chart before release

Lint Chart.yaml before helm package: SemVer 2 version, apiVersion v2 fields, unquoted appVersion, kubeVersion ranges stuck on EOL Kubernetes, and CI files still pinned to Helm 3 (security fixes end 2026-11-11). Runs entirely in your browser — nothing is uploaded.

Free here: Lint every Chart.yaml and CI file in the workspace and show each broken line with the exact replacement line, no key needed.. In the editor: Team key: a dated Helm 4 readiness report (Markdown + JSON) covering every chart in the repo, plus a CI gate that fails the build on any finding. — that part asks for a licence key.

Same engine as the VS Code extension, byte for byte.
