Radar | The missing open-source Kubernetes UI

# Radar > Radar is open-source Kubernetes visibility for platform engineering teams. One Helm chart for self-host (Apache 2.0), or Radar Cloud for fleet aggregation, persistent retention, SSO, and routed alerts. Radar gives engineers a unified view of every Kubernetes cluster they run - topology, event timeline (past the default 1-hour TTL), Helm releases, image filesystem inspection, cluster audits, and an MCP server for AI agents. The full engine is Apache 2.0 and runs from a single binary or Helm chart. Radar Cloud is the hosted control plane that adds multi-cluster fleet view, retention up to 1 year, SAML/OIDC SSO, scoped RBAC, and routed alerts. ## Product - [Product Overview](https://radarhq.io/product): Everything Radar OSS and Radar Cloud ship together - [Issues & root cause](https://radarhq.io/product/issues): Failures classified by subject, folded into the root-cause row, with causal links and confidence labels - [Applications view](https://radarhq.io/product/applications): Workloads folded into the applications they form - health rollups, environment folding, version-skew badges - [Topology](https://radarhq.io/product/topology): Live Kubernetes resource graph - SSE-updated, ELK.js-laid-out, group by namespace or label - [Event timeline](https://radarhq.io/product/timeline): Every K8s event and resource delta, persisted past the kube-apiserver's default 1-hour TTL - [GitOps for Argo + Flux](https://radarhq.io/product/gitops): Fleet and per-app GitOps views with field-level drift, parsed failure diagnosis, and sync/reconcile operations - [Image filesystem viewer](https://radarhq.io/product/image-filesystem): Browse any container image's filesystem - tree, sizes, symlinks - without kubectl exec - [Cluster audit](https://radarhq.io/product/cluster-audit): 31 best-practice checks across security, reliability, and efficiency - [AI via MCP](https://radarhq.io/product/mcp): Model Context Protocol server for Claude, Cursor, Copilot, and other agent clients - [
