GitHub·high signal

Open Design is a local-first, open-source alternative to Anthropic's Claude Design (launched April 17 with Opus 4.7) that hit 20,000 stars in its first week. It provides 19 skills and 71 brand-grade design systems for generating web, desktop, and mobile prototypes plus slides, images, videos, and HyperFrames — all exported as HTML/PDF/PPTX/MP4. Runs on Claude Code, Codex, Cursor, Gemini, and any MCP-compatible client via a stdio MCP server. For builders who want Claude Design's capabilities without the closed-source lock-in, this is the answer.
