Icons

• Lucide is an open source icon library, used under the ISC license. Cerb's guided installer draws its interface icons from Lucide's own geometry.

  Separately, the AI assistants that help design icons in the Icon Builder tend to produce Lucide-like shapes. Nothing in Cerb tells them to – their instructions describe the format and point at Cerb's own icons for its conventions – so that resemblance comes from what the models learned long before they saw Cerb.
