Why Radar?

• Zero install on your cluster — runs on your laptop, talks to the K8s API directly
• Single binary — no dependencies, no agents, no CRDs
• Blazing fast - smart caching, progressive loading, parallelization and other optimizations
• Airgapped-ready — no external network calls, works in isolated environments
• Real-time — watches your cluster via informers, pushes updates to the browser via SSE
• Works everywhere — GKE, EKS, AKS, minikube, kind, k3s, or any conformant cluster
• AI-ready — built-in MCP server lets AI assistants query your cluster through Radar
• In-cluster option — deploy with Helm for shared team access with RBAC-scoped permissions

Views

Topology

Interactive graph showing how your Kubernetes resources are connected in real-time.

• Two modes: Resources (full hierarchy) and Traffic (network flow path)
• Group by namespace, app label, or view ungrouped
• Filter by resource kind — click any node for full details
• Auto-layout powered by ELK.js, live updates via SSE

Resources

Table-based resource browser with smart columns per resource kind.

• Browse all resource types including CRDs
• Search by name, filter by status or problems (CrashLoopBackOff, ImagePullBackOff, etc.)
• Click any resource for YAML manifest, related resources, logs, and events

Image Filesystem Viewer

Inspect container image filesystems directly from the Pod view — no need to pull images locally or exec into containers.

• Click any container image in a Pod to browse its complete filesystem
• Tree view with file sizes, permissions, and symlink targets
• Search files by name across the entire image
• Download individual files for inspection
• Works with public images (Docker Hub, Quay, GHCR) and private registries (GCR, ECR, ACR) using your cluster's ImagePullSecrets
• Disk-based layer caching for fast repeated access

Timeline

Unified timeline of Kubernetes events and resource changes.

• Filter by event type (all or warnings only)
• Resource change diffs showing what changed (replicas, images, etc.)
• Real-time updates as new events occur

Helm

Manage Helm releases deployed in your cluster.

• View all releases across namespaces with status, chart version, and app version
• Inspect values, compare revisions, view release history
• Upgrade, rollback, or uninstall releases directly from the UI

TLS Certificate Management

View TLS certificate details and expiry dates across all namespaces — catch expiring certificates before they cause outages.

• Parses TLS secrets to show certificate subject, issuer, and validity period
• Dashboard-level certificate expiry overview
• Available from the resource detail view for any TLS-type Secret

GitOps

Monitor and manage FluxCD and ArgoCD resources with unified status views and actions.

• FluxCD: GitRepository, OCIRepository, HelmRepository, Kustomization, HelmRelease, Alert
• ArgoCD: Application, ApplicationSet, AppProject
• Real-time sync status, health indicators, and reconciliation countdowns
• Trigger reconciliation, suspend/resume resources, and view managed resource inventory
• Problem detection with clear alerts for degraded or out-of-sync resources
• Note: Topology connections between GitOps resources and managed workloads only appear when both are in the same cluster. FluxCD typically deploys to its own cluster. ArgoCD often manages remote clusters — connect Radar to the target cluster to see workloads, or to the ArgoCD cluster to see Application status.

Traffic

Visualize live network traffic between services using Hubble or Caretta.

• Auto-detects Hubble (Cilium), Caretta, or Istio as traffic data sources
• Animated flow graph showing requests per second between services
• Filter by namespace, protocol, or status code
• Setup
