Sculpt OS version 23.04

(published in April 2023)

Sculpt is an open-source general-purpose OS. It combines Genode's microkernel architecture, capability-based security, sandboxed device drivers, and virtual machines in a novel operating system for commodity PC hardware and the PinePhone. Sculpt is used as day-to-day OS by the Genode developers.

The administrative user interface ("Leitzentrale"): The panel at the top gives access to the live components view (shown), a file browser, and network connectivity. The interactive graph in the center presents the system components with their relationships and allows the user to interactively add/remove components offered by federated software providers.
