What is Loupe for Kubernetes?
Free, open-source desktop client for Kubernetes clusters Loupe is a free, open-source desktop client for Kubernetes.
Our verdict
A clear, honest open-source Kubernetes client: kubectl-matching columns, a diff before every apply, per-context read-only and protected modes, no telemetry and no price. It is young (first release August 2026, version 0.1.7) and I did not run it. Desk-research score 3.5/5.
Full review
Loupe is a free, open-source desktop client for Kubernetes. It reads the same kubeconfig that kubectl uses, connects to the cluster API server straight from your machine and shows pods, workloads, networking, storage, Helm releases and custom resources in one window. It is built by Varun Kruthiventi under the kryptonhq GitHub organization, licensed Apache-2.0, and written with Tauri: a React and TypeScript front end over a Rust core.
What it does
Listings come from the API server’s own table endpoint, so the columns match kubectl get, including for custom resources that were installed a minute ago. Pod views show containers, termination reasons, events and the manifest. Logs stream live with filters, regex, previous-container reading and a merged view across every replica of a Deployment. Edits go through a diff before every apply and conflicts are refused rather than overwritten. Contexts can be marked read-only or protected, and the safeguard is

Edits go through a diff before every apply and conflicts are refused rather than overwritten. Contexts can be marked read-only or protected, and the safeguard is enforced in Rust. A shell in a container, port forwards that survive a rollout, scale, restart, cordon and drain are built in. Since v0.1.6 there is also a Problems view and cluster-wide search, and v0.1.7 added a dashboard.
Cost and privacy
There is no price. The docs say there is no in-cluster component, no operator to install, no service account to create and no telemetry. Loupe holds no credentials of its own: it acts as whoever your kubeconfig says you are, so your RBAC decides what you can see. The code is on GitHub, and Linux packages are GPG-signed.
How I reviewed it
This is desk research on October 2, 2026: the product site, docs, release notes, the GitHub README and the maker’s launch notes. I did not install Loupe or connect it to a cluster, so I cannot judge speed, stability or how the write safeguards feel in practice. The screenshots on the site use demo data.
The product is young. The first release was August 1, 2026 and the current version is 0.1.7, with 10 GitHub stars when I looked. The vendor says Windows installers are not code-signed yet, and an earlier note listed a container shell as not yet built, which the README now says exists. Treat it as a promising early tool rather than a proven replacement for Lens or k9s.
Who it's for
Best for
- Engineers who live in kubectl and want a desktop view; people who left Lens or OpenLens over licensing; teams that want an Apache-2.0 tool they can audit; anyone with a huge kubeconfig; operators who want a protected mode for production contexts
Not ideal for
- Teams that need a mature and long-tested tool with a big plugin ecosystem; people who want AI features or in-cluster components; Windows users who dislike unsigned installers; anyone who wants a hosted or browser version; buyers who need vendor support or SLAs
How we tested
Ashley Richmond desk research, October 2, 2026: loupe.kryptonhq.com home, docs, installation and release pages, the kryptonhq/loupe GitHub README, and the maker LinkedIn and Product Hunt notes. Loupe was not installed or connected to a cluster. Screenshots are the vendor own demo-data images from its site and repository.
What's new
Version 0.1.7 (September 26, 2026) adds the dashboard, Check for Updates in the menu and listings that update on their own. 0.1.6 added Problems and cluster-wide search.

Key features
Live resource browser
Pods, workloads, networking, config, storage, Helm releases and any custom resource, kept current by watches rather than polling.
kubectl-matching columns
Lists use the API server table endpoint, so columns match kubectl get, including custom resource printer columns.
Live logs
Stream pod logs with container selection, timestamps, substring or regex filters, previous-container reading and merged workload logs.
Diff before apply
The YAML tab writes back as a full replace, shows a diff first and refuses to overwrite an object someone else changed.
Safeguards per context
Mark a cluster read-only or protected, so writes are refused or need the context name typed to confirm. Enforced in Rust.
Shell and port forwards
Open a shell in any container and run port forwards that survive a rollout because the pod is resolved per connection.
Problems and search
A dashboard and Problems view surface crash loops, unschedulable pods and pressured nodes, plus cluster-wide search and a command palette.
Secrets without disclosure
Secrets show keys and sizes, with values revealed one at a time on request and redacted in the YAML tab.
Key benefits
- Nothing to configure: It reads your existing kubeconfig and lists the contexts you already have.
- Nothing installed in the cluster: No operator, no service account, no telemetry, per the docs.
- Safer production work: Read-only and protected contexts plus a diff before every apply.
- Handles huge kubeconfigs: The vendor says thousands of contexts open instantly with ranked search.

Pros & Cons
Pros
- Free and Apache-2.0: No price, source on GitHub, and the maker says it will stay free.
- Runs on three platforms: macOS, Linux and Windows builds, with Homebrew and auto-update from v0.1.5.
- Signed releases: macOS builds are signed and notarised, and Linux packages are GPG-signed.
- Open about gaps: Release notes and README state what is missing, including unsigned Windows installers.
Cons
- Very new: First release August 1, 2026, version 0.1.7, and about 10 GitHub stars.
- Windows not signed: The vendor says SmartScreen will warn on first run.
- Solo maintainer: GitHub shows one main contributor, so support depends on one person.
- No plugins or AI: I found no plugin system or built-in AI assistant listed.

Frequently asked questions
Is Loupe free?
Yes. It is licensed Apache-2.0 and the maker says it will stay free. I found no paid tier, trial or account.
Which platforms does it run on?
macOS (Apple Silicon and Intel), Linux (.deb, .rpm, .AppImage) and Windows (MSI and NSIS). On macOS you can install with brew install --cask kryptonhq/tap/loupe.
Does it send data anywhere?
The docs say there is no telemetry and no in-cluster component. Loupe talks to the API server from your machine using your kubeconfig credentials, and the Rust core keeps tokens out of the web view.
Does it work with any cluster?
The docs say it works against any conformant cluster, managed, self-hosted or local such as kind or OrbStack. It sees only what your RBAC allows.
Can it change things in my cluster?
Yes, by editing YAML, scaling, restarting, deleting, cordoning and draining. Each write confirms and shows a diff, and you can mark a context read-only or protected.
How mature is it?
Young. The first release was August 1, 2026 and the latest I saw was 0.1.7 on September 26, 2026. I did not install it, so I cannot speak to stability.
