A fast, lightweight Kubernetes desktop client.

Native, built in Go, and free under the MIT license — no Electron, no daemon, nothing installed in your cluster. It talks to the Kubernetes API straight from your ~/.kube/config: live resources, full RBAC, Helm, Argo CD, Flux and Gateway API.

Live view across contexts — captured from real clusters.

Installs nothing

No agent, no operator, no CRDs, no sidecars. Klustr is a pure client — it talks to the API server the same way kubectl does. Drop the binary on your machine, point it at a context.

Live, never polled

client-go informers push every change the moment it lands — no refresh button, no polling loop hammering the API server. Logs, exec and port-forward run in the app.

Just your kubeconfig

Argo CD, Flux and Helm run through the Kubernetes API — no argocd-server, no flux or helm CLI, no second login. You see exactly what your RBAC allows.

One window, the whole cluster

Built-ins, CRDs, and your GitOps stack

Every built-in kind, the complete RBAC set, auto-discovered CRDs, and native Helm, Argo CD, Flux and Gateway API support — in one window, with nothing installed in the cluster.

Multi-context aggregation

View 2+ clusters as one table with per-context status pings, named groups and color tags so you always know what you're touching.

Access Review

Subject → effective-permission GVR × verb matrix with the binding → role chain behind every ✓. Wildcards and cluster-admin flagged. No impersonation.

Every built-in resource

Workloads, networking, storage, config, admission, autoscaling and the complete RBAC set under a dedicated Access Control group.

Custom Resources

CRDs auto-discovered on connect, grouped by API group and watch-backed — no rebuild to see a freshly installed kind.

Helm

Full Helm v3: install, upgrade, rollback and uninstall with a dry-run preview before any change, plus repo and chart search.

Argo CD & Flux CD

Sync, Refresh, Reconcile and Suspend through the Kubernetes API — no argocd or flux CLI, no extra server.

Gateway API

Typed informers: listener table, per-rule match → backend → weight matrix and RouteParentStatus. Vendor-neutral across implementations.

Logs & exec

Stern-style multi-pod streaming with per-pod ANSI colors, follow and regex — plus an in-app SPDY shell into any container.

YAML, scale & rollout

Monaco editor with a server-side dry-run diff before apply, inline scale / restart / pause, and one-click rollout history rollback.

A tour of the themes

Every shot, a different theme

Captured live from real clusters. Each is rendered in one of Klustr's 12 built-in themes, so the gallery doubles as a tour. Click to enlarge.

Install

The macOS build is signed with a Developer ID certificate and notarized by Apple, so Gatekeeper opens it directly. Linux ships as a tarball and a .deb.
