open-design at 52.5K Stars: Open-Source Claude Design Alternative Hits 40K Stars in Two Weeks With 132 Skills and 150 Design Systems

GitHub·high signal

nexu-io/open-design is a local-first, open-source alternative to Anthropic's paid Claude Design service that reached 40K stars in its first two weeks. It ships 132 composable design skills and 150 brand-grade design systems (Linear, Stripe, Vercel, Notion, Apple) for generating web, mobile, and desktop prototypes plus slides and videos. The key differentiator: it doesn't ship its own AI model — it leverages whatever coding agent CLI is already on your PATH across 16 supported platforms.
