Software you actually own: a cluster manager, a CMS, a terminal for every screen and a menu bar manager for macOS. All of it open source. The cluster manager and the CMS run on a Kubernetes cluster that stands at home.
All projects are at the very beginning. Because development is at such an early stage, many breaking changes are still to come: features, settings and data formats can change from one release to the next.
holzkube-manager
Cluster management
Run Kubernetes on Talos without knowing talosctl by heart — from bare metal to the wall display in the office. One binary, runs even on a Raspberry Pi.
holzcloud-CMS
Websites and shop
As many websites as you like from one program — no JavaScript and no external dependencies, so no cookie banner either. And, if you want, Claude or ChatGPT look after the content over MCP.
holzWave
Terminal for every screen
A terminal emulator written from scratch in Rust: macOS, Windows and Linux today, iOS and Android planned. Tiled panes, tabs and workspaces, SSH, file previews and an AI chat that asks first and, on a Mac with Apple Intelligence, runs completely offline. Beta: packages for all three systems are out (0.0.1-beta1), tested by the author.
holzBar
Menu bar for the Mac
Hide what gets in the way, show it when you need it, on macOS 27 too. Open source, installed through Homebrew, based on Ice by Jordan Baird. Called holzIce until October 2026.
The cluster manager and the CMS run on a Kubernetes cluster at home. So does this page: the cluster is managed with holzkube-manager, and holzcloud-CMS serves the page.
