Create T3 App — Full-Stack TypeScript Starter with Next.js, tRPC & Prisma

Introduction

Create T3 App is an interactive CLI that generates a full-stack TypeScript project following the T3 Stack philosophy: simplicity, modularity, and end-to-end type safety. It lets developers pick from a curated set of libraries rather than starting from scratch or wading through boilerplate.

What Create T3 App Does

• Scaffolds a Next.js project with TypeScript configured out of the box
• Optionally adds tRPC for end-to-end typesafe APIs without code generation
• Integrates Prisma ORM for database access with type-safe queries
• Configures NextAuth.js for authentication with multiple providers
• Sets up Tailwind CSS with sensible defaults and dark mode support

Architecture Overview

The CLI prompts the user for which packages to include, then assembles a project from composable template partials. Each optional library (tRPC, Prisma, NextAuth, Tailwind) has its own partial that merges cleanly with the base Next.js template. The result is a single Next.js app where the API layer uses tRPC routers, the database layer uses Prisma, and authentication flows through NextAuth session providers.

Self-Hosting & Configuration

• Run the CLI with npx, npm create, yarn create, or pnpm create
• Select packages interactively or pass flags like --tailwind --trpc --prisma
• Configure environment variables in the generated .env file for database URL and auth secrets
• Deploy to Vercel, Railway, or any Node.js host with zero additional config
• The generated project includes a ready-to-use Docker configuration for self-hosting

Key Features

• Fully interactive scaffolding with sensible defaults at every step
• End-to-end type safety from database schema to frontend components
• Modular architecture where every optional package can be excluded
• Community-maintained documentation with deployment guides for major platforms
• Regular updates tracking the latest stable versions of all included libraries

Comparison with Similar Tools

• create-next-app — official Next.js starter; minimal, no opinionated stack choices
• Blitz.js — full-stack React framework with built-in auth and RPC; heavier abstraction
• RedwoodJS — full-stack JS framework with GraphQL API layer; different API paradigm
• SvelteKit — full-stack Svelte framework; different frontend ecosystem entirely
• Wasp — DSL-based full-stack framework; generates React + Node code from a config file

FAQ

Q: Do I have to use all the packages in the T3 Stack? A: No. The CLI lets you pick only what you need. A valid T3 app can be just Next.js with Tailwind.

Q: What databases does the Prisma integration support? A: Prisma supports PostgreSQL, MySQL, SQLite, SQL Server, MongoDB, and CockroachDB. Configure the provider in schema.prisma.

Q: Can I use the App Router instead of Pages Router? A: Yes. Recent versions of Create T3 App default to the Next.js App Router with full support for server components.

Q: Is this suitable for production applications? A: Yes. The generated code follows production patterns including environment variable validation, strict TypeScript config, and proper error handling.
