Interactive graph showing how your Kubernetes resources are connected in real-time.
Topology View — Visualize resource relationships
Table-based resource browser with smart columns per resource kind.
Resources View — Browse and filter all cluster resources
Inspect container image filesystems directly from the Pod view — no need to pull images locally or exec into containers.
Image Filesystem Viewer — Browse container image contents
Unified timeline of Kubernetes events and resource changes.
Timeline View — Track cluster activity in real-time
Manage Helm releases deployed in your cluster.
Helm View — Manage your Helm deployments
View TLS certificate details and expiry dates across all namespaces — catch expiring certificates before they cause outages.
Monitor and manage FluxCD and ArgoCD resources with unified status views and actions.
Visualize live network traffic between services using Hubble or Caretta.
Traffic View — See how services communicate in real-time
Track Kubernetes spending with OpenCost integration — no additional configuration needed.
Proactive best-practices scanner with 31 checks across security, reliability, and efficiency — inspired by Polaris, Kubescape, Trivy, and NSA/CISA guidelines. Runs instantly against cached data with zero cluster-side installation.
latest, single-replica deployments, missing PDB/topology spread, pod HA risk (all replicas on same node), orphan services/ingresses, deprecated API versionsget_cluster_audit) for AI-assisted cluster analysisRadar includes a built-in Model Context Protocol (MCP) server that lets AI assistants — Claude, Cursor, Copilot, and others — query your cluster through Radar.
Instead of raw kubectl output (verbose YAML that burns through LLM context windows), your AI gets pre-processed, token-optimized data: topology graphs, health assessments, deduplicated events, and filtered logs. Read tools are strictly read-only; write tools (restart, scale, sync) are clearly annotated and non-destructive.
Enabled by default. Disable with --no-mcp. See the MCP Guide for setup instructions.
For shared in-cluster deployments, Radar supports optional user authentication with per-user Kubernetes RBAC.
No auth by default (local use). See the Authentication Guide for setup.
Radar auto-discovers any CRD in your cluster. Popular tools get dedicated integrations with topology edges, detail views, and AI summaries.
