The Next.js SaaS starter kit with auth, payments, and a database already connected
Better Auth, Stripe billing, Prisma and Postgres, transactional email, and file uploads to R2 or S3. Clone the repo, add your product logic, and skip the weeks you'd spend wiring this together yourself. It already works.

The stack you would have picked yourself
“I cloned it on a Monday, had a working login and checkout by Tuesday afternoon. The auth and Stripe setup alone would have taken me two weeks to figure out solo.”

You'll sink 35+ hours into plumbing before your product does anything
Auth flows, Stripe webhooks, database migrations, email deliverability, S3 permissions. Every SaaS needs it, and none of it makes your product different from the last one. Next Starter ships with all of it already built.
