Building a Scalable AI Directory with Next.js and Tailwind CSS

How I Built an AI Tools Directory in an Internet Café — Next.js + Tailwind + Vercel

Developer Xiaomo Fan built useaitools.me from scratch while working in an internet café in China. The project launched with over 50 AI tools indexed across 6 distinct categories including Writing, Image, and Productivity.

Why This Matters

Building a functional directory site requires balancing rapid shipping with foundational technical requirements like SEO and monetization. While ideal models suggest perfect polish before launch, the reality of indie development necessitates a ship-first approach to validate market demand and navigate affiliate program rejections based on early-stage traffic metrics.

Key Insights

• The project utilizes Next.js 16 and TypeScript to manage 50+ dynamic tool pages and category filtering for improved performance.
• SEO integration including sitemaps and meta tags was implemented early in 2026 to ensure organic growth from day one.
• Affiliate monetization via Rytr offers a 30% recurring commission, though platforms like AppSumo require higher traffic volume for approval.
• Deployment via Vercel and GitHub integration enables a CI/CD pipeline for rapid iteration and building in public.

Practical Applications

• Use Case: Implementing a v1 single-page directory with 20 tools to validate niche interest quickly. Pitfall: Over-polishing features before establishing a user base leads to wasted engineering hours.
• Use Case: Automating SEO via robots.txt and sitemap generation in Next.js to capture search traffic. Pitfall: Neglecting meta tags until post-launch results in poor initial indexing and low visibility.
