  Sovereign identity in the homelab: Zitadel and the RPS spectrum

  Homelab identity with Authelia, Keycloak, Authentik, and Zitadel: forward auth, central IdP, social login, and when each one fits.

On this blog you'll find, on one hand, tools and techniques related to programming and self-hosting, and on the other, personal reflections on information security and digital sovereignty, as well as personal productivity based on eliminating distractions and mental clarity.

I write this blog not because I'm an expert, but as a form of documentation for myself and to help others facing challenges similar to mine. I also write to put my reflections on paper and invite debate on topics I consider vitally important today, such as self-hosting and digital sovereignty in contrast to the cloud-first philosophy that seems to have taken hold in recent years.

Here you won't find quick recipes or thoughtless snippets, and we won't settle for "if it works, don't touch it". We seek to understand technology in depth to gain autonomy, reduce technical debt, and avoid vendor lock-in. Everything I write is meant to help you look beyond superficial functionality and make informed decisions about the tools and systems you use.

This blog is an honest learning space: there will be mistakes, corrections, and discoveries in public. I don't promise easy answers, but I do promise clarity, rigor, and guidance based on practical experience. What you read here isn't just recipes; it's an invitation to think, experiment, and understand every piece of the system we use day to day.
