Agate is built on the shoulders of open-source projects and the broader Fedora Atomic community. None of this would exist without the work of the people and teams below.

Core projects

Universal Blue

The foundational project providing tooling, workflows, and community infrastructure that makes custom Fedora Atomic images practical to build and maintain.

BlueBuild

The build tool used to define, generate, and publish the Agate container image from a declarative recipe.

Fedora Bazzite

The upstream base image that Agate extends — a gaming- and desktop-optimised Fedora Atomic image from the Universal Blue project.

Sigstore / cosign

The image signing and verification infrastructure used to sign every Agate release, letting you verify authenticity before rebasing.

Artifact Hub

The distribution platform where Agate images are published and discoverable. Agate is listed under the agate and agate-alt repositories.

Inspiration

Agate draws inspiration from several community-built custom images that showed what was possible with Fedora Atomic and BlueBuild.

The name

Agate is named after Red Fox Agate — a rare variety of chalcedony quartz found in Patagonia, Argentina, whose vibrant orange-red banding resembles the fur of a red fox. First documented in 1997, it remains one of the more distinctive agates in the mineral world. The name follows the Fedora Atomic Desktop tradition of naming custom images after minerals and rocks, placing Agate alongside projects like Silverblue (silver), Kinoite, and others in that lineage.
