Open-design

open-design.ai/

OpenDesign is an open-source, local-first tool that turns existing coding agents (Claude Code, Codex, Cursor, and others) into a design engine for generating prototypes, landing pages, slide decks, and dashboards from a brief description, rather than being its own standalone AI model. It's positioned as BYOK (bring your own API keys) and explicitly states "Only your prompt and skill context goes to whichever provider you bring keys for" as a privacy commitment. The site backs the open-source claim with specifics rather than vague community language — 97.2K+ GitHub stars, 425 contributors, 21+ supported coding agents, 152+ design systems, and 458+ plugins — all under an Apache-2.0 license.
