Same artifact-first mental model as Claude Design. None of the lock-in. Bring any coding agent, pick any design system, keep your work local.
Star on GitHub 44kOpen Design is the same loop: pick a skill, answer a brief, get an artifact. But instead of routing your prompts through someone else's servers, it detects whichever coding agent you already have installed — Claude Code, Codex, Cursor, Gemini CLI, Qwen, or 11 others — and delegates to them directly on your machine.
Skills are plain Markdown files. Design systems are portable. Projects live in SQLite. Nothing leaves your laptop unless you choose to publish.

Capabilities
A design tool that wires into the agent you already use, with the skills and design systems already built.
01
No built-in AI. Detects 16 coding-agent CLIs on your PATH — Claude Code, Codex, Cursor, Devin, Gemini CLI, Qwen, Copilot, and more — and delegates design execution to the one you trust.
BYOK via OpenAI-compatible proxy fallback02
Web prototypes, SaaS landings, dashboards, mobile apps, slide decks, social carousels, login flows, paywalls, and more. Each skill is a plain SKILL.md file — forkable, composable, yours.
prototype · deck · app · template03
Linear, Stripe, Vercel, Airbnb, Tesla, Notion, Apple, Anthropic, Figma, GitHub, and dozens more — each with real color tokens, type scales, and component rules extracted from the source.

Projects live in SQLite on your disk. Tabs, conversations, and previews persist across sessions. Export to HTML, PDF, PPTX, or ZIP. Import your Claude Design exports and keep working.
HTML · PDF · PPTX · ZIP · MarkdownHow it works
Choose from web prototypes, slide decks, dashboards, mobile apps — 31 skills pre-loaded with templates, layout libraries, and checklists.
Interactive question forms lock down your brief before generation starts — output type, visual tone, brand, target platform. No costly redirections mid-flight.
Your agent produces a complete, standalone HTML artifact. Live preview in a sandboxed iframe. Export as PDF, PPTX, or ZIP when you're ready to share.
No cloud lock-in. No per-seat pricing. Just a design tool that respects your stack.
