What is freelens?

What it is

Freelens is a free and open-source user interface for managing Kubernetes clusters. It is distributed as a standalone desktop application for macOS, Windows, and Linux, and it exists inside the cloud-native ecosystem alongside the containers, DevOps, and Kubernetes tooling that its topic list names. The project is written in TypeScript and released under the MIT license, and it reached its current shape over roughly two years of development. The public repository carries more than five thousand stars and over three hundred forks, with an active issue tracker and community channels on Discord and Reddit.

The concrete problem it addresses is the daily friction of working with Kubernetes clusters without leaving a graphical environment. Operators who need to inspect workloads, navigate cluster state, or reason about resources typically move between command-line tools and scattered dashboards. Freelens puts that work into one standalone application rather than a browser-hosted service, so the interface is available on the same machine from which the cluster is administered. Its stated aim is to reduce the complexity of Kubernetes management by presenting an intuitive interface over the objects a cluster exposes.

Key capabilities

  • Provides a graphical user interface for managing Kubernetes clusters from a standalone desktop application.
  • Runs natively on macOS, Windows, and Linux, with no browser or server-side deployment required.
  • Supports Kubernetes 1.22 and later as its target cluster version.
  • Falls back to a bundled kubectl for older clusters, with a separately installed binary selectable in Preferences.
  • Ships through platform-native package channels, including Homebrew on macOS and DEB, Snap, Flathub, and AUR packages on Linux.
  • Publishes its core as the @freelensapp/core package on npm.
  • Maintains unit tests, integration tests, and linting checks in continuous integration.

Who uses it and how

  • Platform engineers who administer clusters from a laptop install the desktop build and connect it to the clusters they operate.
  • Developers working in containerized environments use the interface to inspect workloads without switching to terminal commands for every check.
  • Teams running clusters older than version 1.22 use the bundled kubectl fallback, or point the application at a different binary through Preferences.
  • Linux users on Debian, Fedora, Mint, openSUSE Leap, Ubuntu, Arch, Manjaro, or Tumbleweed

Requirements

Kubernetes 1.22 or later. Older clusters fall back to the bundled kubectl, which may not work correctly; a different one can be set in Preferences.

Downloads

See the releases page and download the right package for your system.

macOS

macOS 12 or later is required.

Download either the PKG (installer) or DMG (image) package from the releases page. Both arm64 (M1 chip or newer) and amd64 (Intel) variants are available.

All binary packages are built on macOS 15 and should be compatible with newer systems.

Homebrew

Run the following command:

brew install --cask freelens

Linux

Linux with GNU C Library 2.34 or later is required. It is provided ie. by Debian 12, Fedora 35, Mint 21, openSUSE Leap 15.4, Ubuntu 22.04 and by rolling release distributions like Arch, Manjaro or Tumbleweed.

Download DEB or RPM (package) or AppImage (executable) from the releases page. Both arm64 (aarch64) and amd64 (x86_64) variants are available.

All binary packages are built on Ubuntu 22.04 and should be compatible with new systems.

AppImage

The Linux AppImage file requires libz.so and libfuse.so.2. You can add them by running:

sudo apt install libfuse2 zlib1g-dev

Run the application with additional arguments:

./Freelens*.AppImage --no-sandbox --ozone-platform-hint=auto --enable-features=WebRTCPipeWireCapturer --enable-features=WaylandWindowDecorations --disable-gpu-compositing
Flatpak

The package is available on the Flathub App Store for Linux.

Use GNOME Software application or run the following commands:

flatpak install flathub app.freelens.Freelens
flatpak run app.freelens.Freelens

The application is sandboxed. It includes bundled kubectl and helm commands and uses the ~/.kube/config file by default.

Flatpak adds wrappers for the aws, doctl, gke-gcloud-auth-plugin, and kubelogin tools, running them as commands from the host system.

The terminal uses /bin/sh by default, but it can be switched to, for example, /bin/bash for a sandboxed environment or /app/bin/host-spawn for a host environment.

Snap

The package is available on the Snap Store for Linux.

Use App Center application or run the following command:

snap install freelens --classic
APT repository

Run the following commands:

curl -L https://raw.githubusercontent.com/freelensapp/freelens/refs/heads/main/freelens/build/apt/freelens.asc | sudo tee /etc/apt/keyrings/freelens.asc
curl -L https://raw.githubusercontent.com/freelensapp/freelens/refs/heads/main/freelens/build/apt/freelens.sources | sudo tee /etc/apt/sources.list.d/freelens.sources
sudo apt update
sudo apt install freelens
Arch User Repository

The package is available on the Arch User Repository (AUR).

Check the freelens-bin package page.

Windows

Windows 10 or later is required.

Download the EXE (NSIS) or MSI installers from the releases page.

Both the x64 (amd64) and arm64 versions of the Windows binaries are provided. However, an EXE installer (NSIS) itself is x86 binary only even if it installs arm64 application and then installs to C:\Program Files (x86)\Freelens path by default.

The version of the MSI package has the last 4th digit always 0 and this is a limitation of this package format.

Portable

Download the Portable EXE from the releases page. It is a self-contained executable that can be run without installation.

WinGet

The package is available in WinGet Community repository.

Run the following command:

winget install Freelensapp.Freelens

The --silent option is supported to suppress all UI.

The --scope user or --scope machine option can be used to install it either to local user directory or to C:\Program Files.

WinGet installs the application from EXE installer (NSIS).

Scoop

The package is available in the Scoop command-line installer for Windows.

Run the following command:

scoop bucket add extras
scoop install freelens

Scoop uses MSI package to install the application.
