What it is

Radar is an open-source Kubernetes interface for platform engineering teams and AI agents. It brings topology, events, Helm, GitOps, image internals and audits into one interface. Its live graph shows Deployments, Services and Ingresses with traffic, TLS health and cross-namespace dependencies. Radar can run locally as a single binary with a kubeconfig or in-cluster through Helm, and desktop apps are available for macOS, Linux and Windows. Built-in integrations include Argo, Flux, Cilium, Istio, Karpenter, KEDA, Crossplane, cert-manager, OpenCost, Kubecost, Prometheus, Trivy and Velero. Radar OSS is free forever, supports unlimited clusters and nodes, and sends no cluster data out, though it makes one anonymous version check that can be blocked. Cloud Free supports up to three clusters and 100 hosted investigations per month. Paid plans start at $149 per cluster per month for Team; Enterprise costs $299 per cluster per month. Cloud offers AI investigations and alerts to Slack or webhooks. It streams viewed resources, events and logs through its control plane without storing them.
