If you’ve been paying $20 a month for Claude Design and burning through your weekly token allowance in under thirty minutes, there’s now a free, self-hosted alternative that runs the same multi-agent design workflow entirely on your own machine. It’s called Open-Design, it’s Apache 2.0 licensed, and it just crossed 40,000 GitHub stars weeks after launch.

What Open-Design Does

Claude Design’s core value proposition is multi-agent design automation: feed it a prompt or a reference image, and a coordinated team of AI agents handles research, layout, copy, asset generation, and code — producing design artifacts that would take a human hours. Open-Design replicates that workflow but routes tasks to CLI-based AI agents running locally instead of Anthropic’s proprietary backend.

According to the project’s GitHub repository (nexu-io/open-design), the tool supports 19 Skills and 71 brand-grade Design Systems and can generate:

  • Web, desktop, and mobile prototypes
  • Presentation slides
  • Images and videos
  • HyperFrames (interactive design artifacts)

Output can be exported as HTML, PDF, PPTX, or MP4 with a sandboxed preview environment.

The 16+ Agent Backends

The project’s headline number is its breadth of supported AI agent backends. Based on the GitHub repository description, confirmed supported CLI agents include:

  • Claude Code (Anthropic)
  • OpenAI Codex CLI
  • Cursor Agent
  • Gemini CLI (Google)
  • GitHub Copilot CLI
  • OpenCode
  • Qwen (Alibaba)
  • DeepSeek TUI
  • Hermes
  • Kimi

The full list extends to 16+ backends, meaning you can swap between providers based on availability, cost, or output quality for different design tasks.

Ollama Support: Fully Local, Zero Cloud

The most significant feature for privacy-sensitive users and air-gapped environments is Ollama integration. Ollama lets you run open-source models like Llama, Mistral, and Phi locally without any cloud API calls. Open-Design’s Ollama support means the entire design pipeline — prompting, generation, rendering — can run on your hardware with no data leaving your machine.

For regulated industries, this is the feature that makes the comparison to Claude Design’s $20 plan more than just a cost argument. It’s a fundamentally different data handling model.

How to Get Started

⚠️ Accuracy note: The following installation steps are based on standard open-source project conventions for this type of tool. Always refer to the official README on GitHub for the exact, current commands before running anything.

The project is available at github.com/nexu-io/open-design. Based on the repository structure and standard CLI tool conventions, installation typically follows this pattern:

# Clone the repository
git clone https://github.com/nexu-io/open-design.git
cd open-design

# Review the README for exact setup steps
cat README.md

You’ll need at least one supported CLI agent installed. The minimal setup is a local Ollama instance with a capable model, which gives you a fully private workflow at zero API cost.

Refer to the official documentation for the exact installation commands, configuration options, and agent setup instructions. The project is actively maintained and the README is the authoritative source.

Why It’s Growing So Fast

Open-Design hit 40,000 GitHub stars within weeks — a growth rate that puts it in the same league as the fastest-growing developer tools of 2026. The reasons aren’t hard to identify:

  1. Cost: Claude Design’s $20/month plan has hard usage limits that frustrated power users quickly discover. Unlimited local runs change the calculus entirely.

  2. Flexibility: Being able to mix Claude Code for architectural reasoning, Gemini CLI for research synthesis, and a local Llama model for asset generation in the same workflow isn’t possible with any single commercial provider.

  3. Privacy: The local-first architecture means your design briefs, brand assets, and client work never leave your machine.

  4. Apache 2.0 license: Commercial use is permitted. Teams can integrate Open-Design into internal tooling or build products on top of it without licensing concerns.

The Catch

As with any project that replicates a commercial product’s functionality, the gap is in polish and support. Claude Design’s UX is intentionally non-technical; Open-Design assumes you’re comfortable with CLI tools, dependency management, and occasional debugging.

The quality of output also depends heavily on which agent backend you use and how capable the underlying model is. Running Ollama with a 7B parameter model will produce different results than routing tasks to Claude Code with Anthropic API access.

For developers and technically-savvy designers, the tradeoff is clearly worth it. For teams that need a no-configuration design tool with vendor support, Claude Design or similar commercial offerings still have a role.
