What it is

CLI that scaffolds a typesafe full-stack Next.js app from a short set of prompts: TypeScript, tRPC, Prisma or Drizzle, Tailwind and NextAuth. At 29,000+ GitHub stars it defines the T3 Stack conventions that a large share of tutorials and Stack Overflow answers assume.

Why it earns a slot

A clean, opinionated starting repo that agents know well because it is heavily represented in training data. Prompts about tRPC routers and Prisma schemas land more reliably here than in a bespoke folder structure.

Know before you commit

Latest release is 7.40.0 from November 2025, still targeting Next.js 15 and NextAuth v5, so roughly nine months without a release as of August 2026. Fine to start from, but you upgrade dependencies yourself.
