The Universal Blue project builds a diverse set of continuously delivered operating system images using Fedora Atomic Desktop's support for OCI/Docker containers. That's nerdspeak for the ultimate Linux client: the reliability of a Chromebook, but with the flexibility and power of a traditional Linux desktop.

These images represent what's possible when a community focuses on sharing best practices via automation and collaboration. One common language between dev and ops, and it's finally come to the desktop.

We also provide tools for users to build their own image using our templates and processes, which can be used to ship custom configurations to all of your machines, or finally make the Linux distribution you've long wished for, but never had the tools to create.

At long last, we've ascended.

Base Images

Universal Blue maintains a set of base images built from Fedora Atomic Desktops and then enhanced with additional hardware support and fixes. Note that these images are lightweight by design, and do not ship with many of the enhancements of our other images.

Universal Blue images are endlessly customizable and may be derived into new images through the use of a Containerfile and our GitHub build actions. We look forward to seeing what you create from them!

Universal Blue is made up of alumni from companies like:

Amazon Web Services (AWS) Canonical Chainguard Cloud Native Computing Foundation (CNCF) Microsoft Red Hat
And community members like you!
We're always looking for people to join, all skill levels and areas of expertise are welcome.
Universal Blue is not affiliated or endorsed by any of the above companies.

Cloud Native

All of Universal Blue rests on the idea of cloud-native. We leverage standard cloud tools like the OCI standard images, Docker/Podman, and GitHub to build our images. This is a much lighter and faster way of building and deploying Linux environments to users that allows professionals in the industry to leverage their pre-existing knowledge to create a better desktop Linux experience for everyone.

We feel that a dedicated group of enthusiasts can automate a large amount of toil that plagues existing Linux desktops today. This is achieved by reusing cloud technologies as a delivery mechanism to deliver a more reliable experience.


It's important for users to have insight on the health of the projects they depend on. Below you'll find a detailed summary of pulls and contributions across the Universal Blue organization.
