🎨 The open-source Claude Design alternative. 🖥️ Local-first desktop app. 🖼️ Your coding agent becomes the design engine: prototypes, landing pages, dashboards, slides, images & video — real files, HTML/PDF/PPTX/MP4 export. 🤖 Claude Code / Codex / Cursor / Gemini / OpenCode / Qwen & 20+ CLIs via BYOK.

What it solves

Open Design addresses the limitations of closed-source design tools by providing an open-source, local-first alternative to proprietary agentic design systems. It allows users to move beyond text-based LLM outputs to functional, brand-compliant design artifacts like web prototypes, pitch decks, and motion graphics that can be directly consumed and edited by coding agents.

How it works

The platform operates as a filesystem of functional skills, design templates, and plugins that coding agents (like Claude Code, Cursor, or Copilot) can read, write, and remix. It uses a DESIGN.md file as a brand contract to ensure all generated outputs—ranging from HTML prototypes to MP4 motion graphics—adhere to specific design systems. It supports various workflows via an MCP server, allowing it to be integrated directly into mainstream coding agents.

Who it’s for

  • Developers and Coding Agents: Users who want to integrate high-quality design capabilities directly into their existing IDEs and CLI workflows.
  • Designers and Product Teams: Teams looking for an open-source way to automate repetitive design workflows and maintain brand consistency through programmatic design systems.
  • Content Creators: Users needing to generate high-resolution images, video, and presentation decks using agentic workflows.

Highlights

  • Multi-modal Artifacts: Generates web/mobile prototypes, live dashboards, pitch decks (PPTX/PDF), images, and motion graphics (MP4).
  • Agent-Native Integration: Supports over 25 coding agents via MCP server installation.
  • Composable Skills: Uses a plugin-based architecture to extend generation capabilities on demand.
  • Local-First Desktop App: Available as a native application for macOS and Windows.
  • HyperFrames Integration: Includes an agent-native video framework for programmatic motion graphics.
