Open Design: Use Your Coding Agent as a Design Engine

Open Design is an open-source, local-first alternative to Anthropic's closed Claude Design (Opus 4.7, April 2026), auto-detecting 11 coding-agent CLIs including Claude Code, Codex, and Gemini CLI as interchangeable design engines. It ships 31 composable Skills and 72 brand-grade Design Systems, enforcing a 5-dimensional self-critique loop and pre-flight checklists before artifact emission into a sandboxed iframe. Unlike OpenCoworkAI's Electron-bundled open-codesign, OD is web-deployable via Vercel with full BYOK at every layer and no model lock-in. Frontend engineers and design-system teams who want Claude Design-quality artifact workflows without cloud dependency or per-seat pricing should evaluate this immediately.
