Immutable Linux for gaming & development

SoltrOS is an immutable Linux desktop and server operating system built on Fedora CoreOS, designed for gaming and development workloads. Updates are delivered weekly as atomic images—no major version upgrades or compatibility issues to manage. The system rolls forward seamlessly, tracking Fedora's release cycle without disruption. Choose your release track: LTS follows Fedora's stable releases for production reliability. Unstable tracks upcoming features from alpha and beta channels, with safety guardrails in place. Both tracks deliver a clean, performant system that evolves continuously without the traditional upgrade cycle.
