Open Design: A Two-Week, 40K-Star Open-Source Alternative to Claude Design
When Anthropic released Claude Design in April 2026, Figma's stock dropped roughly 6.84% within minutes—Adobe followed. The market read it as Anthropic selling finished work, not just model calls: design files, slide decks, and prototype pages.
But the market missed the cost problem.
Quotas Kill the Magic
PC World ran a hands-on test. One reviewer used Claude Design for 25 minutes and burned through 80% of the Claude Pro token quota. Community estimates put Claude Pro at roughly 1 million tokens per month, so:
- 20-minute design session ≈ 800K tokens
- 20 hours of design work per month ≈ 32M tokens
- At Opus 4.7 public pricing (~$15 per million tokens) ≈ $48 in cost
- The user pays only $20
- Claude Code
- Codex
- Cursor
- Kimi
- DeepSeek TUI
- Claude Design triggered an immediate market reaction: Figma down ~6.84% in under 20 minutes.
- 25 minutes of Claude Design = 80% of Claude Pro weekly tokens (PC World test).
- Heavy users hit ~32M tokens/month, costing ~$48 against a $20 subscription.
- Anthropic responded with stricter quotas rather than price increases.
- Open Design reached 40K stars in two weeks as a free, uncapped alternative.
- It supports 16 AI coding CLIs (Claude Code, Codex, Cursor, Kimi, DeepSeek TUI, and more).
- It integrates directly with the Codex desktop app.
- PC World hands-on test of Claude Design token consumption
- Opus 4.7 public pricing: ~$15 per million tokens
Anthropic is losing money on every heavy design user. That is a structural loss no subscription model can sustain. The only options are higher prices or stricter caps—and Anthropic chose stricter caps, letting users burn through a week's quota in half a day.
The magic is gone. AI is not too weak; it is too expensive to run.
What Open Design Does
Two weeks after Claude Design's launch, an open-source project called Open Design hit 40K GitHub stars. It is free, has no usage caps, and supports 16 different AI coding CLIs, including:
Any of these can be turned into a design engine. Crucially, Open Design can be installed directly into the Codex desktop app, so users do not need to switch tools.
Why It Matters
Claude Design proved the demand: AI can produce finished design artifacts, not only suggestions. But the pricing model makes it uneconomical for sustained professional use. Open Design decouples the design capability from a single vendor's quota system, letting users pick the model and CLI that fit their workflow and budget.
