Kor is a Go CLI tool that discovers unused (orphaned) Kubernetes resources such as ConfigMaps, Secrets, Services, Roles, PVCs, and many more. It can run as a kubectl plugin, Docker container, Helm cronjob, or deployment exposing Prometheus metrics.

Use cases

• find unused configmaps and secrets in my kubernetes cluster
• identify orphaned kubernetes resources to reduce costs
• detect unused service accounts and roles in k8s
• clean up stale deployments and statefulsets
• run periodic scans for unused kubernetes resources via cronjob
• export prometheus metrics for unused kubernetes resources

When to choose

• you want to audit and clean up unused Kubernetes resources across many resource types
• you need scheduled scans with Slack notifications or Prometheus metrics
• you prefer a kubectl plugin or single Go binary with no cluster-side agents

When to avoid

• you need multi-cluster cost analysis dashboards (consider the commercial KorPro or other tools)
• you need automatic deletion with policy enforcement rather than discovery
• you are not running Kubernetes
