Next.js SaaS Starter Kit
Auth, Stripe & Supabase, ready to ship
I built RedactAI, an AI content generation SaaS, and realized the infrastructure — auth, billing, database — was the most tedious but also the most reusable part. So I extracted it into a standalone starter kit.
What's included:
- Next.js (App Router) + TypeScript
- JWT authentication, working out of the box
- Stripe — subscriptions and webhooks already wired up
- Supabase integration
- Server-side rate limiting (Upstash Redis) and input sanitization
- Setup docs, running in under 30 minutes
It's not a tutorial project — it's the actual code from a live product. $39, one-time.

This is my first standalone product. Feedback on positioning and pricing is very welcome.

I like that the starter kit comes from code that has already survived production instead of being built specifically as a template.
I'll be interested to see which part developers consistently mention as the reason they choose it. Those patterns will probably reveal whether the product is really about saving setup time, reducing implementation risk, or giving founders a faster path to shipping.
Thanks! I’ve just sent it over.
Looking forward to hearing your thoughts whenever you have a chance.
