About Open Design

Open Design is an open-source, local-first AI design workspace that transforms coding agents like Claude Code, Codex, Cursor, and Gemini into a powerful design engine. It is agent-native, meaning it plugs into the agent you already run, and allows you to generate prototypes, landing pages, slide decks, dashboards, brand systems, and HTML videos directly on your machine. The tool features over 21 supported coding agents, 151 design systems, 217 plugins, and 80.5K GitHub stars. It is licensed under Apache-2.0 and built by Powerformer, Inc. Design artifacts are created from briefs, templates, or visual directions, and can be previewed in a sandboxed environment and exported as HTML, PDF, PPTX, or MP4. HyperFrames enables video creation from designs. Open Design is BYOK (bring your own keys) and supports local file access, Figma exports, and code repos. It learns user preferences over time through design system memory.

FAQ

What is Open Design?
Open Design is the official open-source AI design workspace from the nexu-io/open-design project. It turns a local coding agent — such as Claude Code, Codex, Cursor, Gemini CLI, OpenCode, or Qwen — into a design engine driven by composable skills and portable DESIGN.md systems.
Is Open Design official?
Yes. The canonical project lives at https://open-design.ai/ and the source is on GitHub at https://github.com/nexu-io/open-design.
How is Open Design different from Claude Design?
Claude Design is a hosted product tied to a single vendor. Open Design is local-first, open source under Apache-2.0, and BYOK: you bring your own agent, credentials, and DESIGN.md system.
Is Open Design an open-source Claude Design alternative?
Yes, Open Design is the open-source, local-first alternative to Claude Design, offering agent agnosticism, full local control, and a free tier.
What are Open Design model credits and how are they used?
Open Design model credits are a USD-denominated balance used for hosted models. Each hosted AI model call deducts from your balance by usage. BYOK calls to provider models do not consume credits. Each subscription grants a matching credit amount every billing cycle.
What is the Free plan's limited-time trial credit?
The limited-time trial credit is a free welcome benefit given to every new Open Design Cloud sign-up. It unlocks a trial pool of hosted models (currently Grok-4.5) for 7 days. After the trial credit expires, the Free plan reverts to local CLI plus BYOK.
