## The Hook

Radar is a single-binary Kubernetes web UI that shows what is broken, why, and what changed — topology, resources, Helm, GitOps, live traffic, audit, upgrade impact — with a built-in MCP server so agents can inspect the same cluster context.

## What's Good

Apache-2.0 (skyhook-io/radar). Free path: curl the install script or grab a release binary, then `kubectl radar` — no account, no agents on the cluster, no cloud sync required. Telemetry is opt-in (anonymous usage counts / coarse cluster facts only). Built-in MCP lets coding agents query cluster state through Radar. Useful when kubectl YAML dumps are too slow for day-2 ops and you want a laptop UI plus an agent-readable surface. ★~3.6k.

## The Catch

Browser UI, not a terminal — if you live in kubectl/k9s only, this is a different seat. The MCP reads and operates through Radar’s cluster context; it does not run agents for you. Scope RBAC tightly: whatever the kubeconfig can do, the UI and MCP can attempt. Paid Radar Cloud adds hosted multi-cluster and SSO while the OSS binary stays free. ★ climbed fast for the project’s age (~3.6k in under a year) — judge it on substance (views, MCP, single binary), not the badge. Young product; pin a release.

## Verdict

Apache-2.0 K8s web UI + MCP when day-2 cluster visibility belongs in a browser — OSS binary free forever; Cloud is the paid multi-cluster/SSO line; watch the star heat.
