What does Duply do?
Duply does one thing and does it simply: it gives you a DESIGN.md file that encodes the visual language of popular design systems. You pick a brand like Stripe, Linear, or Vercel, hit copy, and get a markdown file with typography, colors, spacing, and tone. Then you drop that file into your AI coding agent — Cursor, Copilot, whatever you use — and the agent builds your UI in that exact style. No manual CSS, no guessing.
The gallery shows previews of each system, so you can see what you're getting. Tags like "Minimal", "Bold", "Fintech" help you filter. Each system lists its primary font. The process is refreshingly straightforward. Duply also sells a Launch Kit ($225 one-time) that bundles a starter codebase with mock data and pre-configured integrations (Supabase Auth, Stripe Payments, GA4, Resend, PostHog, Vercel deploy). This is useful if you want a running project that already respects the design system.
This is perfect for developers who want clean, consistent design without hiring a designer or learning CSS frameworks. Indie hackers can prototype quickly with a professional look. Teams can maintain brand consistency across projects. It's not a design tool — it's a bridge between existing design systems and AI code generation.
