Open Design: Free Local Alternative to Claude Design

Anthropic launched Claude Design on April 17 behind a $20/month paywall. Twelve days later, the open-source community shipped a free, MIT-licensed alternative that runs locally and keeps your designs entirely yours.

Open Design takes a text prompt and returns a working prototype backed by 71 brand-grade design systems — Linear, Stripe, Vercel, Airbnb, Tesla, Notion, and more. It hit 18K GitHub stars in five days and is already running in production teams.
