We're building Fair Price Index — a stock valuation tool that covers 37,000+ stocks. Yesterday we went from zero to a live production website on a custom domain in a single afternoon. Here's how.
The stack:
We designed a complete interactive prototype as a React component in Claude. Then we took that design to v0 by Vercel, pasted a detailed prompt describing every section, and v0 generated a production-ready Next.js page. One click to deploy, DNS pointing from GoDaddy to Vercel, and fairpriceindex.com was live.
What we learned:
v0 is excellent for translating a well-defined design into Next.js code
Having a complete prototype before touching v0 saved us from burning credits on iteration
The Vercel + GoDaddy DNS setup took about 15 minutes including propagation
Don't forget sitemap.xml and robots.txt — v0 doesn't generate them automatically
What's next:
We're building programmatic SEO pages for all 37,000 stocks (fairpriceindex.com/stock/AAPL etc.) using Next.js ISR, and a React Native mobile app with Expo. The entire backend is a single API that feeds both the web and the app.
If you're building in fintech or doing programmatic SEO at scale, I'd love to connect and compare notes.
