📹 <a href="https://github.com/SametKUM/klustr/raw/main/docs/hero.gif" target="_blank" rel="noopener nofollow">43-second feature tour</a> — see Klustr drive multiple clusters, sync Argo apps, stream logs, and run a Helm Upgrade with Wait-until-ready,
all in one walkthrough.
I’ve been building Klustr for the past few months — a free, MIT-licensed native Kubernetes desktop client. It runs as a small Go binary (Wails — Go + native webview, no Electron), reads your
existing <code>~/.kube/config</code>, and doesn’t deploy anything in your cluster. No CRDs, no operators, no extra RBAC. Standard <code>client-go</code> over the K8s API.
<h2>Why I built it</h2>
Lens going paid + telemetry turned me off, k9s is great in a terminal but lacks dialogs / diffs / log highlighting, and Headlamp’s plugin model is fine but the core feels thin. I wanted one binary
with Helm, Argo CD, and Gateway API first-class — not behind plugins or installer wizards.
<h2>Highlights</h2>
<ul>
<li>Multi-context aggregated mode — drive 2+ clusters as one virtual cluster, every table interleaves them with a Context column.</li>
<li>Helm v3 — install / upgrade / rollback with dry-run preview, talks to <code>helm.sh/helm/v3</code> directly (no <code>helm</code> binary on PATH).</li>
<li>Argo CD auto-detected from the <code>applications.argoproj.io</code> CRD — Sync / Refresh fire through the K8s API. No <code>argocd-server</code> ingress, no Argo login, no <code>argocd</code> CLI required, just kubeconfig</li>
</ul>
permission to update Applications.
<ul>
<li>Gateway API with typed <code>sigs.k8s.io/gateway-api</code> informers — full listener / RouteParentStatus / match → backend → weight matrix.</li>
<li>RBAC subject → effective-permissions matrix with binding trace and implicit-group expansion. Wildcards / cluster-admin highlighted.</li>
<li>Stern-style aggregated logs, Monaco YAML edit with diff, port-forwarding manager, rollout history with one-click rollback.</li>
<li>12 themes (6 light, 6 dark), no telemetry.</li>
</ul>
<h2>Install</h2>
<ul>
<li>macOS (Apple Silicon): <code>brew tap sametkum/klustr &amp;&amp; brew install klustr</code></li>
<li>Arch / CachyOS / Manjaro: <code>paru -S klustr-bin</code></li>
<li>Debian / Ubuntu: download the <a href="https://github.com/SametKUM/klustr/releases/latest" target="_blank" rel="noopener nofollow">.deb from the releases page</a> and <code>sudo apt install ./klustr*amd64.deb</code></li>
</ul>
<h2>Honest caveats</h2>
Windows and macOS Intel aren’t shipped yet — both on the roadmap, build from source for now. No auto-update.

Happy to take questions or feature requests. Especially curious which Kubernetes workflow currently makes you reach for a terminal even when a GUI is open — that’s the gap I want to close next.

Daily Open Source Tools

Klustr is a free, MIT-licensed native Kubernetes desktop client built as a single Go binary using Wails (Go + native webview, no Electron). It reads your existing kubeconfig without deploying anything to your cluster — no CRDs, operators, or extra RBAC. Key features include multi-context aggregated mode for managing multiple clusters simultaneously, built-in Helm v3 with dry-run preview, Argo CD integration via the K8s API (no argocd CLI needed), Gateway API support, an RBAC subject-to-effective-permissions matrix, stern-style log aggregation, Monaco YAML editor with diff, and port-forwarding management. Available for macOS Apple Silicon, Arch-based distros, and Debian/Ubuntu. Windows and macOS Intel support is on the roadmap.

Klustr — open-source Kubernetes desktop client. Nothing installed in your cluster. Helm, Argo CD, Gateway API built in.
