Build AI SaaS products faster: My starter kit with Next.js, Supabase & GPT

🚀 I've been building GPT-based tools and MVPs lately, and I got tired of setting up the same things over and over:

• Authentication
• GPT integration
• Responsive UI
• Middleware for route protection
• .env and setup instructions

So I built a starter kit for AI SaaS products.

It uses:

• ✅ Next.js 14 with the new app router
• ✅ Supabase Auth (email/password)
• ✅ OpenAI GPT integration
• ✅ TailwindCSS UI
• ✅ Middleware session protection
• ✅ Ready-to-use .env.local and clean folder structure

🧠 Why I built it

I needed to launch internal tools fast, and I didn’t want to rebuild the same boilerplate every time. After using this kit for my own MVPs, I decided to polish and release it.
