T3 Stack vs create-t3-turbo 2026

TL;DR

Both starters come from the same maintainers (t3-oss) and share the same TypeScript-first philosophy. The decision comes down to whether you need mobile:

• create-t3-app — single Next.js web app, 5-minute setup, web-only SaaS
• create-t3-turbo — Turborepo monorepo with Next.js web + Expo React Native, shared packages across apps

If you're building a web application, use create-t3-app. If you're building a web app and a mobile app that share the same tRPC API and Prisma schema, use create-t3-turbo. Don't add monorepo complexity speculatively.

What is create-t3-app?

create-t3-app is the official CLI for the T3 Stack, built by Theo Browne and the t3-oss community. It generates a single Next.js application with a curated set of TypeScript-first packages that share a single, unified type system from database schema to React component.

npm create t3-app@latest

The CLI prompts you to include or exclude each package:

• tRPC — end-to-end typesafe API (router on server, typed hooks on client)
• Prisma — schema-first ORM; rename a column and TypeScript surfaces every broken query
• Tailwind CSS — utility-first styling
• NextAuth.js — OAuth, magic link, and credential authentication

The defining feature is the type safety chain. Define a tRPC router procedure on the server, and its input/output types flow automatically to the React component consuming it — no manual types, no code generation step, no sync required. If you change the Prisma schema, the TypeScript error appears immediately in the components that query that data.

create-t3-app targets a single Next.js App Router application. There is no native support for a React Native mobile app sharing the same backend. If you know you'll need mobile eventually, you'll be refactoring later.

What is create-t3-turbo?

create-t3-turbo extends the T3 philosophy into a Turborepo monorepo. The same t3-oss maintainers built it for teams that need to ship both a web app and a mobile app from a single codebase, with the same API, database schema, and shared UI components.

npx create-turbo@latest -e https://github.com/t3-oss/create-t3-turbo

The monorepo structure:

apps/
  nextjs/        ← Next.js web app (App Router)
  expo/          ← React Native mobile app
packages/
  api/           ← Shared tRPC router (imported by both apps)
  db/            ← Shared Prisma schema + client
  ui/            ← Shared React components
  validators/    ← Shared Zod schemas

Both apps/nextjs and apps/expo import from packages/api and packages/db. When you add a new database table or a new tRPC endpoint, both apps get it immediately with full type safety. There's no API duplication and no schema drift between platforms.

The auth setup also differs: create-t3-turbo uses Clerk by default (with Clerk Expo SDK for native) rather than NextAuth.js, since NextAuth doesn't have a React Native story.

Developer Experience

create-t3-app DX

Fast onboarding. The CLI generates a working app in under five minutes. Hot reloading, Prisma Studio, and the Next.js dev server are all you need day-to-day. Everything lives in one directory — no workspace dependencies to debug, no cross-package type resolution issues, no Turborepo pipeline configuration.

The iterative pace is fast because the feedback loop is tight. You edit a Prisma model, run db push, and the tRPC router picks it up. You add a new router procedure and the client component gets intellisense immediately.

The constraint appears later: if you decide a React Native app should share your backend, you'll spend time extracting the tRPC router and Prisma setup into shared packages. That migration is well-documented but non-trivial — plan on a few days to do it cleanly.

create-t3-turbo DX

Higher upfront investment. Turborepo introduces concepts that are unfamiliar to developers coming from a single Next.js project: workspace package dependencies, tsconfig path aliases, build pipelines, and the order in which packages must be compiled before apps can import them.

A common first-hour issue: packages/db needs to generate the Prisma client before apps/nextjs can import it. Turborepo handles this through its pipeline config, but debugging why an import fails requires understanding that pipeline.

Once past setup, the DX payoff is real. Turborepo's remote caching means CI pipelines only rebuild packages that changed — a 5-minute CI run stays 5 minutes even as the codebase grows. The shared type safety between web and native is the main draw: define a tRPC route once, call it from both the browser and the React Native app with identical types.

Repository Complexity

With create-t3-app you have a single package.json, a single node_modules, and a flat project structure. Dependencies are simple. Upgrading a package is one command.

With create-t3-turbo you have a root package.json, separate package.json files per app and package, and Turborepo orchestrating builds across all of them. Upgrading @trpc/server requires checking that both apps and the shared API package are on compatible versions. Dependency hoisting rules add another layer of configuration.

For a team of 1-3 developers on a web-only product, create-t3-turbo's overhead costs more than it saves.

When to Use create-t3-app

• Building a web-only SaaS product
• Solo founder or small team (1–3 developers)
• First time with the T3 Stack — learn the patterns before layering on monorepo tooling
• You want to ship fast without Turborepo overhead
• No concrete plan for a React Native mobile app in the next 6 months

When to Use create-t3-turbo

• Building both a web app and a mobile app from day one
• Your team has prior monorepo experience (Nx, Turborepo, Lerna)
• You want shared type-safe tRPC API between web and React Native
• Multiple apps (e.g., a customer-facing app and an internal dashboard) sharing a backend
• You want Turborepo's build caching to keep CI fast as the repo grows

For most solo founders and early-stage teams, start with create-t3-app. You can migrate to a Turborepo monorepo later once you have evidence that you need mobile. Premature monorepo complexity has killed more side projects than any architectural shortcut.
