I built 17 AI tools for developers in 4 months. Here's what I learned about shipping fast.

A developer built 17 free multilingual AI tools in four months using a repeatable stack: React, Vite, Supabase, and Gemini Edge Functions.

The biggest lessons were to keep each tool simple, make outputs easy to share, and focus on distribution from day one.

Programmatic SEO and IndexNow helped the tools get discovered and drive long-tail traffic.

The creator says early mistakes included adding ads too soon, weak promotion, and over-engineering authentication.
