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 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 - [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 1-hour TTL - [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): 30 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 ## Use cases - [Solutions](https://radarhq.io/solutions): What Radar is for - troubleshooting, multi-cluster ops, GitOps, Helm, compliance - [For SREs](https://radarhq.io/for/sre): Cut incident MTTR without adding another dashboard - [For Platform Engineering](https://radarhq.io/for/platform-engineering): Self-serve Kubernetes visibility, org-wide - [For DevOps Leaders](https://radarhq.io/for/devops-leaders): Kubernetes as a business function ## Compare - [All comparisons](https://radarhq.io/vs): How Radar stacks up again
