radar
Radar provides modern Kubernetes visibility that is local-first, needs no account and has no cloud dependency. It shows cluster topology, an event timeline and service traffic, and also lets you browse resources, stream logs, exec into pods, inspect container image filesystems, manage Helm releases, monitor GitOps workflows (FluxCD and ArgoCD) and forward ports. It installs with `curl -fsSL https://get.radarhq.io | sh && kubectl radar`.
The README's reasons to use it: nothing is installed on your cluster (it runs on your laptop and talks to the Kubernetes API), it is a single binary with no agents or CRDs, it is airgapped-ready with no external network calls, it watches the cluster in real time through informers and pushes updates over SSE, it works on GKE, EKS, AKS, minikube, kind, k3s or any conformant cluster, and it includes a built-in MCP server (beta, enabled by default, disable with --no-mcp) that gives AI assistants token-optimised data instead of raw kubectl YAML. For shared in-cluster deployments via Helm it supports proxy-mode or OIDC authentication with per-user Kubernetes RBAC through impersonation. Further sections cover TLS certificate management, cost insights and a cluster audit. The code is Apache-2.0 licensed.
