Open Design — Open-Source, Bring-Your-Own-Agent Design Workspace
An open-source (Apache-2.0) desktop design workspace that turns your own coding agent — Claude Code, Codex, Cursor, Gemini and 21+ others — into a design engine for prototypes, landing pages, dashboards, slides and HTML video. Local-first, BYOK, no vendor lock-in.
Open Design is a desktop AI design workspace: instead of shipping its own model, it turns your existing coding agent into a design engine, turning a one-line brief into runnable prototypes, landing pages, dashboards, slides, and even HTML video.
The headline is no lock-in: Apache-2.0 open source, fully local, BYOK, with support for 21+ agents including Claude Code, Codex, Cursor, Gemini CLI, and Copilot. Prompts go straight to the provider you choose — Open Design runs no servers and never touches your data.
It positions itself as the open-source alternative to the closed, hosted, model-locked Claude "Design": the flow is brief → template → visual direction → artifact → memory, with a portable DESIGN.md so one design system works across every agent.
Built for indie hackers, designers, engineers, PMs, and marketing teams who want fast prototyping without vendor lock-in.
FAQ
What is Open Design?
An open-source (Apache-2.0) desktop AI design workspace: it ships no model of its own — it turns your existing coding agent into a design engine that generates prototypes, landing pages, dashboards, slides, and HTML video from natural language.
Is Open Design free?
The software is free and open source (Apache-2.0). You only pay API costs to the provider you choose (Anthropic, Google, OpenAI, etc.) — it's BYOK.
Which AI coding agents does it support?
21+ coding agents, including Claude Code, Codex, Cursor, Gemini CLI, GitHub Copilot, OpenCode, and Qwen.
How is it different from Claude's official Design?
Claude Design is closed, hosted, and model-locked; Open Design is open source, fully local, BYOK with no lock-in, and uses portable DESIGN.md files so one design system works across every agent.
Does my data get uploaded?
Not to Open Design — it runs no servers. Prompts go straight to your chosen provider and files stay on your machine.
