I Built a Zero-Login Postman Alternative in 5 Weeks. My Cofounder Is an AI and I Work Long Shifts.

A solo developer built a zero-login API request builder in five weeks using Claude as an AI co-developer.

The app stores data only in localStorage, offers three free AI generations monthly, and a $12/month Pro tier via Stripe.

The stack uses Next.js 16, React 19, TypeScript strict mode, and Tailwind CSS v4, and monthly infra costs are about $23.

Deployment issues included Vercel blocking pushes due to git identity and a misspelled env var that caused 404s for customers.
