Huashu Design: The Open Source Repo That Cloned Claude Design

If you are constantly hitting Claude Design usage limits, Huashu Design is the workaround. It is an open-source GitHub repo that packages Claude Design's capabilities -- web apps, mobile apps, slide decks, motion design -- as a Claude Code skill. That means you use your normal coding agent usage allocation, not the separate (and more restrictive) Claude Design usage pool. Chase ran head-to-head comparisons and found the outputs to be nearly identical.

The Problem: Claude Design Usage Limits

Claude Design is a powerful prototyping tool, but it comes with its own usage limits that are separate from Claude Code. For heavy users who are designing and iterating frequently, those limits become a real bottleneck. The natural question is whether there is a way to get Claude Design quality output without burning through the Claude Design allocation.

The Solution: Huashu Design Skill

Huashu Design is a skill that replicates Claude Design's capabilities inside Claude Code. Because it runs as a skill within your coding agent, it draws from your standard Claude Code usage -- not the Claude Design usage pool. The repo covers all the major Claude Design capabilities:

• Interactive prototypes (web and mobile apps): Single-file HTML, real iPhone bezel rendering, clickable, Playwright-verified. Typical time: 10-15 minutes.
• Slide decks: HTML browser presentations with editable PPTX output, text frames preserved. Typical time: 15-25 minutes.
• Motion design: MP4 at 25/60fps with interpolation, GIF output with palette optimization, background music support. Typical time: 8-12 minutes.
• Design systems: Side-by-side comparisons with live parameter tweaks and cross-browser testing. Typical time: 10 minutes.

Head-to-Head Comparison

Chase ran tests comparing identical prompts in Claude Design versus the Huashu Design skill in Claude Code. The results were effectively the same. Landing pages, design system implementations, and slide decks all produced comparable output quality. He estimates Huashu Design gets you 90% of the way to Claude Design output, which for most use cases is more than sufficient.

The same parity held when feeding in design systems and generating slide decks -- the skill handles the full range of Claude Design's core workflows.

Key Takeaways

• Huashu Design is an open-source skill that replicates Claude Design capabilities inside Claude Code
• It uses your standard Claude Code usage allocation, bypassing Claude Design's separate usage limits
• Covers web apps, mobile apps, slide decks, motion design, and design system generation
• Head-to-head comparisons show output quality at roughly 90% parity with Claude Design
• Free, open source, and available now on GitHub
