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
• Fast on big clusters — tested on tens of thousands of pods, with responsive views and live updates under real cluster churn
• Private by design — your cluster data stays on your machine. No account, no agents, no cloud sync. Usage reporting is off unless you opt in, and then sends only anonymous usage counts and coarse cluster facts: Kubernetes version, platform, node-count range, known integrations (what Radar sends)
• Airgapped-friendly — runs as a single binary against the Kubernetes API and works in locked-down environments with outbound egress blocked
• 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 agents inspect, investigate, and operate your cluster through Radar
• In-cluster option — deploy with Helm for shared team access with RBAC-scoped permissions

"Have Radar deployed at work. As far as Kubernetes dashboards go, this is one of the best." — u/TheRealNetroxen

Installation

Quick Install:

curl -fsSL https://get.radarhq.io | sh

Homebrew:

brew install kubectl-radar

Also available from our tap: brew install skyhook-io/tap/radar.

Then run: kubectl radar. Quick install, PowerShell, Homebrew, and Scoop also set up the radar shorthand. Krew and direct downloads use kubectl radar unless you add your own radar symlink.

More install options — Desktop App (macOS/Linux/Windows), Krew, Scoop, In-Cluster Helm

CLI

Krew (kubectl plugin manager):

kubectl krew install radar

Scoop (Windows):

scoop bucket add skyhook https://github.com/skyhook-io/scoop-bucket
scoop install radar

PowerShell (Windows):

irm https://get.radarhq.io/install.ps1 | iex

Custom install location (macOS/Linux):

curl -fsSL https://get.radarhq.io | INSTALL_DIR="$HOME/.local/bin" sh

Quick install writes to /usr/local/bin unless INSTALL_DIR says otherwise. The directory is created if missing, and needs to be on your PATH for radar and kubectl radar to resolve.
