100% transparent

Our code and our finances, completely public

At Citadel, we value transparency. Every part of our code, every cent and satoshi we receive, everything we build and everything else we do is completely transparent.

Have a look at our code or view our finances.

Bitcoin is an ecosystem built on a foundation of free and open source software and ideas. Progress in Bitcoin is made as we build on each other's work. Bitcoin users must have full freedom over the hardware and software infrastructure they use – freedom to fork, freedom to change, freedom to run the programs they want without any intermediaries.

Unlimited possibilities

With our app store, you can run literally anything on your node.

Not only does Citadel include a large selection of apps already available, anyone from the community can build their own app store and you can install it. This even includes app stores built for Umbrel!

A modern Umbrel alternative

100% transparent and a lot more up-to-date

Citadel started out as a modified version of Umbrel. Our goal was to keep the oiginal idea of Bitcoin: Build in the open. Unlike Umbrel, which only publishes their code after releases, we stay transparent with what we do and allow you to use our code for any purpose.

We also ensure all of our apps are up to date. On Umbrel a lot of apps are outdated. On Citadel, app updates are made available almost daily (If there are any updates available upstream).

Citadel also has a more secure community app store system. We still try to allow importing apps from Umbrel community app stores, but because of Umbrel's insecure design, not all apps can be imported into Citadel's safe app system.
