The open-source, local, agent-driven design platform. From idea to prototypes, web pages, slides, and HTML video — on your own machine.
In April 2026, Claude Design proved for the first time that an LLM can truly design — not write about design, but produce real design artifacts. Yet it is closed-source, paid, and cloud-only: locked to one model, with no agent choice, no self-hosting, no BYOK. Open Design sets that capability free.
Design happens on the desktop. Local files, Figma exports, and code repos are directly readable; agents get full terminal power.
Claude Code, Codex, and Cursor on your machine are already powerful. Open Design wires them into a complete design workflow.
Every choice becomes design systems, preferences, and memory, so the next generation lands closer to what you want.
Compared to Claude Design, our monthly bill dropped from $500 to ~$73 — over 80% less.
