Azentrius.

Digital sovereignty

Software you own.

Open-source tools for your own infrastructure and devices: add-ons for Cockpit, a desk display for Claude Code and Codex, an Android voice app, a self-hosted tool for passing on Instagram and Facebook posts, and a theme for Home Assistant. Local control, transparent dependencies: each project page says what it needs and what it talks to.

Package repository

Installed in a minute

Set up the Azentrius package repository once. Cockpit then lists the add-ons under Applications, ready to install, and your system's updates keep them current. Every package was built by the release workflow of its own repository; the repository checks that before it takes one.

Debian and Ubuntu

curl -fsSLO https://packages.azentrius.com/azentrius-repository.deb
sudo apt install ./azentrius-repository.deb
sudo apt update

Fedora and RHEL

sudo rpm --import https://packages.azentrius.com/azentrius.asc
sudo dnf install https://packages.azentrius.com/azentrius-repository.rpm

What we stand for

Why Azentrius

Privacy first

Privacy is not a feature, it is the foundation of every decision.

Control

The tools run on your servers and devices. Where a project needs an outside service, its page names it.

European roots

Our website, package repository and analytics run on our own servers in the EU.

Openness

Open architectures, auditable code, no black boxes.
