Get Kabacus.

Kabacus is in active development. Builds follow the master branch; the source is on GitHub .

Available now

Linux app (RPM and DEB)
The KDE app and kabacus-cli in one native package, built against your distribution’s Qt and Kirigami. The rolling latest release follows every push to master. It registers the .kabacus file type.
```
sudo zypper install ./kabacus-*.rpm   # openSUSE Tumbleweed
sudo apt install ./kabacus-*.deb       # Debian
```
Latest release on GitHub
Package repository
Fedora 43–45, CentOS Stream 9–10, RHEL-compatible 9–10 (with EPEL), openSUSE Leap 16 and Tumbleweed get RPMs from the repository at repo.hallb.me, for x86_64. MicroOS, Aeon and Kalpa use the Tumbleweed RPM.
repo.hallb.me
Server (container image)
kabacus-server serves shared books over an HTTP API and an MCP endpoint, and hosts the web app at /app/. The image holds no settings for any one machine.
```
podman pull ghcr.io/brannengh/kabacus-server:latest
```

Web app and desktop shell
The web app runs from a server at /app/ today. Windows, macOS, Flatpak and Android builds of the desktop shell are built by the project’s CI but not yet published for download.
Not planned
RHEL 8, SUSE Linux Enterprise, openSUSE Leap 15 and aarch64 have no packages: the platforms either lack Qt 6 and KDE Frameworks 6 or are out of support.
