krusty

A native Kubernetes desktop client written in Rust with GPUI Kit.

What it does

krusty is a fast, native desktop UI for everyday Kubernetes work:

• Live list and watch views for Pods, Deployments, DaemonSets, Jobs, Services, Ingresses, ConfigMaps, Secrets, PersistentVolumes, PersistentVolumeClaims, and Nodes.
• Dedicated detail panes for every resource, including conditions, capacity, images, addresses, taints, labels, annotations, and the raw manifest.
• Live CPU and memory charts in node and pod details when metrics-server is available.
• Cluster context switching from the title bar with per-tab namespace filtering.
• Split the editor into two side-by-side groups, each with its own tabs and namespace filter, for live comparisons.
• Multiple kubeconfigs managed inside the app, including pasted credentials.
• Light, dark, and system themes.
• Responsive layouts that keep the list and detail panes side by side on wide windows and switch to a focused detail view on narrow ones.

Getting started

You need a Rust toolchain that supports edition 2024 and a kubeconfig. The app reads $KUBECONFIG or ~/.kube/config on startup and can also store kubeconfigs added inside the app.

cargo run --release

For iterative development with automatic rebuilds and restarts:

./scripts/dev.sh

On Linux, install the font and windowing development packages before building. For Debian/Ubuntu:

sudo apt-get install build-essential pkg-config \
  libfontconfig1-dev libfreetype6-dev libwayland-dev \
  libx11-xcb-dev libxkbcommon-dev libxkbcommon-x11-dev \
  libxcb1-dev libxcb-render0-dev libxcb-shape0-dev \
  libxcb-xfixes0-dev libxcb-randr0-dev libxcb-composite0-dev \
  libxcb-damage0-dev libxcb-present-dev libxcb-xkb-dev

Packaging

Release builds are produced by .github/workflows/build.yml:

• Linux x86_64 and arm64 binaries, packaged as .tar.gz archives.
• Flatpak bundles for x86_64 and arm64 from packaging/flatpak/io.github.GT020.Krusty.yml.
• A macOS arm64 DMG.

Pushing a v* tag builds all targets and attaches them to a GitHub release.

Local packaging helpers:

./scripts/package-linux.sh
./scripts/package-macos.sh
