Why
Bazzite started as a project to resolve some of the issues that plague SteamOS, mainly out of date packages (despite an Arch base) and the lack of a functional package manager.
Despite this project also being image-based, you are able to install any Fedora package straight from the command line. These packages will persist across updates (So go ahead and install that obscure VPN software you spent an hour trying to get working in SteamOS). Additionally, Bazzite is updated multiple times a week with packages from upstream Fedora, giving you the best possible performance and latest features - all on a stable base.
Bazzite ships with the latest Linux kernel and SELinux enabled by default with full support for secure boot (Run just enroll-secure-boot-key and enter the password ublue-os if prompted to enroll our key) and disk encryption, making this a sensible solution for general computing. (Yes, you can print from Bazzite)

Contributor Metrics
Special Thanks
Bazzite is a community effort and wouldn't exist without everyone's support. Below are some of the people who've helped us along the way:
- rei0260 - For creating our logo and overall branding.
- evlaV - For making Valve's code available and for being this person.
- ChimeraOS - For gamescope-session and for valuable support along the way.
- Jovian-NixOS - For supporting us with technical issues and for creating a similar project. Seriously, go check it out. It's our Nix-based cousin.
- Steam Deck Homebrew - For choosing to support distributions other than SteamOS despite the extra work, and a special thanks to PartyWumpus for getting Decky Loader working with SELinux for us.
- cyrv6737 - For the initial inspiration and the base that became bazzite-arch.
Build Your Own
Bazzite is built entirely in GitHub and creating your own custom version of it is as easy as forking this repository, adding a private signing key, and enabling GitHub actions.
Familiarize yourself on keeping secrets in github. You'll need to generate a new keypair with cosign. The public key can be in your public repo (Your users need it to check the signatures), and you can paste the private key in Settings -> Secrets -> Actions with the name SIGNING_SECRET.
We also ship a config for the popular pull app if you'd like to keep your fork in sync with upstream. Enable this app on your repo to keep track of Bazzite changes while also making your own modifications.
