Presets

A preset is a JSON file that describes a complete stack configuration. Instead of answering CLI prompts, you can pass a preset URL to scaffold instantly.

Built-in Presets

minimal

Next.js + UI package + Tailwind 4 + Biome. The simplest starting point.

npx create-turbo-stack --preset minimal

saas-starter

Full-stack SaaS: Supabase (DB + Auth), tRPC v11, shadcn/ui, i18n, Sentry, PostHog, React Email.

npx create-turbo-stack --preset saas-starter

api-only

Hono standalone API with Drizzle ORM and Upstash rate limiting. No frontend.

npx create-turbo-stack --preset api-only

Using a Community Preset

Anyone can host a preset at any URL:

npx create-turbo-stack --preset https://example.com/my-stack.json

Preset Schema

Presets must conform to the preset JSON schema.

Validation

Presets are validated with Zod. Invalid combinations are rejected:

supabase-auth requires database.strategy: "supabase"
i18n only works with web-facing apps (Next.js, SvelteKit, Astro, Remix)
CMS integrations only work with Next.js apps
App names and ports must be unique
consumes must reference existing packages
