Razorfin

The gaming desktop, honed to an edge.

Razorfin is Bazzite with the COSMIC desktop: the same gaming-ready, atomic Fedora base underneath, and System76's fast Rust-built shell on top.

−200 m · the build

Three layers, one edge

Gaming-ready base

Bazzite ships Steam, Proton, and a graphics stack tuned for play: HDR, VRR, gamepads, and broad hardware support working from first boot.

COSMIC desktop

System76's desktop, written in Rust. Tiling when you want it, floating when you don't, and settings that don't need a page of extensions.

Atomic to the bone

The whole OS is a signed container image. Updates apply on reboot, and if one bites, bootc rollback returns you to the previous deployment.
