Open-source Kubernetes UI and MCP server for diagnosing issues, tracing topology, and managing clusters.
Radar is a Kubernetes interface for engineers and AI agents, combining a human-focused UI with an MCP server. It folds failures into root causes with blast radius, shows a live resource topology, keeps event timelines beyond the default retention, and supports Argo CD and Flux GitOps visibility plus Helm chart inspection and cluster audits. It is aimed at platform teams and on-call engineers running many clusters. Radar OSS is free and open source under Apache 2.0, while Radar Cloud adds alerts, AI investigations, shared views, and fleet-wide history on paid plans with a free tier.
