I Built a $0/Month SaaS with Next.js + Vercel — Here's My Stack

As a solo developer, I built a full AI fortune telling website that costs me literally $0/month to host. Here's my exact tech stack.

The Stack

• Framework: Next.js (Pages Router) — SSR + dynamic routes for 108 pages
• Hosting: Vercel — free tier, auto-deploy from GitHub/Gitee
• AI API: DeepSeek — one reading costs ~$0.002
• Payments: PayPal.Me — zero integration cost
• SEO: 108 dynamic pages + sitemap + Google/Bing Search Console

Cost Breakdown

• Vercel hosting: $0 (free tier)
• Domain: $0 (vercel.app subdomain)
• AI API: ~$0-5/month
• Payments: 0% (PayPal.Me)
• Total: $0-5/month

Key Decisions

1. No database — access tokens stored in-memory
2. No auth system — PayPal → auto-activate, no login
3. Static + Dynamic hybrid — blog pages static, fortune pages dynamic
4. 108 SEO pages — every Zodiac sign, Tarot card, Numerology number
