Open-source tools for your own infrastructure and devices. Local control, transparent dependencies: each project's page says what it needs and what it talks to.

Cron Jobs · Cockpit add-on
Every cron job and systemd timer on a server in one place: safe crontab edits, the result of every run, run now, and conversion to systemd timers. Project page
Image Update Monitor · Cockpit add-on
Configured, running and newest version of every Docker container, with updates that dump the database first and a rollback at a click. Project page
Update Gaps · Cockpit add-on
The updates a server misses although Software Updates lists none, and why: held packages, Ubuntu Pro fixes, pending restarts, stale package lists. For Debian and Ubuntu. Project page
Security Monitor · Cockpit add-on
Per port, whether the internet, the VPN or the private network reaches it and which rule decides; who logs in; what weakens the containers. For Debian and Ubuntu. Project page
Status Board · Cockpit page
The state of the Azentrius add-ons on every host of Cockpit's host switcher, from one central host: one row per host, one tile per add-on. Project page
Host Settings · Cockpit add-on
A message through ntfy, e-mail or both when an Azentrius add-on on the server needs attention. It shows what the ntfy server needs and checks that the topic is closed to anyone without a login. Project page
Stellwerk · Desk display
Every Claude Code and Codex session on a wide second screen, with their permission requests to allow or deny right there. Runs on your machine only. Project page
Lautwerk · Android app, prototype
Voice conversations with Claude and OpenAI on your own API keys; chats and keys stay encrypted on the phone. Talks to the provider you choose. Project page
Sharewerk · Self-hosted web app
Share an Instagram or Facebook post from your Android phone and get it back as a pack to share: images, video stills, transcript and caption. Runs on your own server. Project page
Azentrius Theme · Home Assistant
Ink, paper and gold for Home Assistant, light and dark as your profile says. Your own instance serves the fonts. Project page
packages.azentrius.com · Package repository (source)
APT and RPM repository for the Cockpit add-ons, so Cockpit lists them under Applications. Every package is checked against the build provenance of its own repository.
Azentrius is the framework for software projects with one aim: tools that people and organisations run themselves, with their data under their own control. Where a project needs an outside service, such as an AI provider, its page says so.
- Privacy first. Privacy is not a feature, it is the foundation of every decision.
- Control. The tools run on your servers and devices.
- European roots. Our website, package repository and analytics run on our own servers in the EU.
- Openness. Open architectures, auditable code, no black boxes.
