Kapstan automates Kubernetes addon upgrades end-to-end. It reads changelogs, detects breaking CRD changes in Helm charts, rewrites your YAML manifests, and delivers a ready-to-merge PR — for ArgoCD, cert-manager, ingress-nginx, and 40+ CNCF addons. Zero cluster access. Works with GitOps, Renovate, and EKS/GKE/AKS.
