🎨 Best DeepSeek Harness Design Plugin. 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 / DeepSeek Harness / OpenCode & 20+ CLIs via BYOK.

What it solves

OpenDesign is an open-source alternative to Claude Design, providing a local-first desktop application for creating design artifacts. It solves the problem of closed-loop design agents by turning the design process into a filesystem of functional skills, templates, and plugins that can be read and remixed by existing coding agents on a user's machine.

How it works

The application acts as a design engine that connects to various coding agents (such as Claude Code, DeepSeek Harness, Cursor, and GitHub Copilot) via MCP, CLI, or native runtime adapters. It uses a DESIGN.md file as a brand contract to ensure visual consistency. Agents generate artifacts—such as web prototypes, mobile apps, decks, and motion graphics—which are then rendered in a sandboxed iframe for live preview and iteration.

Who it’s for

It is designed for designers and developers who want an agent-native design workflow that integrates with their existing CLI tools and local coding agents, moving away from pixel-pushing in traditional canvas-based tools like Figma.

Highlights

  • Multi-Artifact Support: Generates web/desktop/mobile prototypes, live dashboards, multi-slide decks, images, and HyperFrames motion graphics.
  • Broad Agent Compatibility: Supports 26 distinct local CLI executables and OpenAI-compatible endpoints via BYOK.
  • Export Options: Artifacts can be exported to HTML, PDF, PPTX, and MP4.
  • Design Systems: Uses brand-grade DESIGN.md files to extract and refine a brand's visual language.
  • HyperFrames Integration: Includes an agent-native video framework for rendering code-driven motion graphics to MP4 via headless Chrome and FFmpeg.
