I built a Next.js 15 + Supabase boilerplate after wasting 80 hours on repetitive setup

Every time I started a new SaaS project, I spent days on the same boring setup:

• Auth (email + social login)
• Dashboard layout
• Billing integration
• Landing page
• TypeScript config + Tailwind

After the 4th project, I decided to build my own boilerplate. I took the best parts from my previous work, cleaned everything, added proper documentation, and packaged it.

What's inside:

• Next.js 15 (App Router)
• Supabase (auth, database, realtime)
• Stripe subscription billing
• Ready-to-use dashboard
• Landing page template
• TypeScript + Tailwind CSS

It saves about 40–80 hours of work. I'm selling it for a one-time $79.

Question for you: Do you build your own boilerplate from scratch every time, or do you buy/use open-source starters? I'm curious what other indie hackers prefer.
