Choose the workspace built for how you work.
Culltron OS is the local-first desktop environment that runs the whole ecosystem. Every edition ships free — with the Lite apps and open-source tools built in. The Lite apps come bundled with the OS only; upgrade any app to Max or Ultra X26 when you need more.
The clean everyday desktop.
A calm, safe workspace for everyday computing — browse, read, view files and run the Lite apps you need, with nothing you don’t. Free to download and keep.
Home, Creator, Dev or Secure.
Every edition is the same Culltron OS core, free to run. The difference is which Lite and open-source apps ship built in.
Every edition is local-first and runs fully offline. Lite apps are included free as part of Culltron OS only — they're not sold, downloaded or packaged separately. Open-source / rebranded-open-source tools are free; Max and Ultra X26 are paid upgrades. Secure-stack components (Browser, VPN-aware networking) are powered by supported open-source technology.
