Powered by the future, delivered today.

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 ship community best practices out-of-the-box, on top of a Fedora base.

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.

Our Images


Advantages over traditional Linux desktops

  • Reliable, atomic updates with built in rollback
    • Built using OSTree-enabled OCI compliant images
    • Hosted on ghcr.io
      • Ninety (90) days of image archives allowing for flexible rollback options
      • Globally distributed via CDN for fast image downloads
      • Images signed with industry standard sigstore tools
  • Known-good State and Fewer Failures
    • Installation designed to last for the life of the hardware with minimal maintenance
    • Significantly reduced configuration drift
    • Kernel mods preinstalled on the image - including Nvidia drivers
  • Community Maintained
    • The project is maintained by a community of cloud-native contributors with an explicit mission
  • Unbridled customization
    • Craft your perfect image from scratch or derive from others
  • Clean separation of the base system from applications and your data
  • Rebase back to Fedora without reinstallation
    • Not a new distribution, an atomic layer of customization on Fedora that can be removed

Community

Whether you want async discussion, live support, or to learn about the project, we are here for you!

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 with 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.
