A guide to Open Design, the Apache-2.0 open-source alternative to Claude Design: an interactive canvas that prompts ideas into real exportable files, works with any model via your own API keys, and runs locally with no caps.

What's inside
  • An interactive canvas: describe it, watch it build, refine in place
  • Real exportable files — HTML, PDF, PPTX, MP4 — not trapped mockups
  • Bring any model: Claude, ChatGPT, or local, via your own keys
  • 20+ coding agents work out of the box
  • Apache-2.0, no subscription, no usage caps — just a GitHub repo

Prompt Ideas Into Existence — Without the Paywall

Open Design is a community-built, local-first canvas that does what Claude Design does — animated sites, prototypes, UI concepts — with no usage limits and no monthly subscription. Fully open source under Apache-2.0.

Figma for the Agent Era

An interactive canvas where you describe what you want and refine it in place. The outputs are real files you own — real CSS, fonts, and components exported as HTML, PDF, PPTX, or MP4, or deployed in one click. Websites, prototypes, dashboards, decks, images, and video from one workspace.

What's in the Guide

Why it undercuts the SaaS version: bring your own key and connect Claude, ChatGPT, or local models; 20+ coding agents work out of the box; switching engines is a config change. No subscription, no caps — you only pay your own API usage.

The full breakdown is in the PDF.
