🎨 Best DeepSeek Harness Design Plugin
OpenDesign is the open-source Claude Design alternative — a local-first native desktop app for macOS and Windows that turns AI coding agents into design engines. It generates web prototypes, desktop and mobile UIs, live dashboards, decks, images, video, and HyperFrames motion graphics using real CSS, real fonts, and real component systems — not mockups. Your team's DESIGN.md becomes a brand contract shared across models. The Plugins catalog of composable Skills + rendering templates lets designers version control their visual language like code. OpenDesign supports DSH (dsh) as a native runtime: connect once and all structured thinking, tool calls, and session history stay inside the OpenDesign workflow. DeepSeek V4 Flash and V4 Pro are supported. 89k+ GitHub stars — the largest open-source design-agent project.
Install
[desktop app — download from open-design.ai]Download the macOS or Windows installer from open-design.ai. DSH integration: in OpenDesign, connect DSH as a native runtime to get structured thinking, tool calls, model discovery, cancellation, and session resume. Generated files stay in the OpenDesign workflow for live preview. Cloud service at open-design.ai/zh/pricing/ for hosted GPT, Claude, and DeepSeek models plus image generation (GPT Image 2.0, Seedream 5.0 Pro).

FAQ
- How do I connect DSH to OpenDesign?
- In the OpenDesign app, go to Settings and add DSH as a runtime (see open-design.ai/zh/agents/deepseek-harness-design/ for the guide). Generated files then appear in the OpenDesign preview and export workflow.
- What types of artifacts can OpenDesign generate?
- OpenDesign generates: web prototypes, desktop apps, mobile UIs, live dashboards, multi-slide decks, images, video, and HyperFrames motion graphics. Output is real HTML/CSS/components, exported as HTML, PDF, PPTX, or MP4.
- What is a DESIGN.md?
- A DESIGN.md is a brand contract file that lives in your project directory. It captures your design system — typography, color, spacing, component rules — in a format AI agents can read and enforce across every generated artifact.
