Welcome to TunaOS

Modern Cloud-Native Enterprise Linux​

TunaOS is a set of desktop operating systems that use Bootc. Enterprise Linux 10 is the base: AlmaLinux and CentOS Stream. TunaOS is a fork of Bluefin LTS for the next generation of enterprise desktops.

Enterprise Linux gives stability and long-term support. Developers and workstation users also need new tools. TunaOS supplies both.

✨ Why TunaOS?​

  • 🖥️ Latest GNOME: The newest GNOME on a stable base, with the Enterprise Linux toolchain. You get new desktop features and a stable system.
  • 🍺 Baked-in Homebrew: Homebrew is installed. You get immediate access to a large library of command-line tools and fonts.
  • 📦 Bootc Technology: Modern container technology makes the system immutable, reliable, and easy to reproduce.
  • 🏢 Enterprise DNA: AlmaLinux 10 and CentOS 10 are the base. Support continues for as many as 10 years.
  • 🛍️ Flathub Enabled: Flathub is on at installation. A full set of desktop applications is available immediately.
