Introduction

Welcome to the TurboJet documentation. TurboJet is a fullstack Next.js starter kit organized as a Turborepo monorepo. This checkout hosts the public marketing site and docs; shared packages cover auth, API, database, payments, mail, and more so you can wire a product app without rebuilding foundations.

What is TurboJet?

TurboJet helps you ship production-ready web applications faster. The Next.js surfaces in this repository are:

• apps/marketing — public landing page, legal pages, Mayar storefront checkout, and the Hono API at /api
• apps/docs — this documentation site (Fumadocs)

Shared logic lives in packages/* — UI, database, auth, payments, env validation, i18n, mail, storage, and AI. There is no apps/saas or mail-preview app in this checkout; email preview runs via the @repo/mail package script.

App architecture

Each app is a standalone Next.js application with its own layouts and configuration. They share packages for UI, env, i18n, payments, and (where used) auth, database, and API.

Use apps/marketing for homepage, legal pages, SEO, storefront checkout, and API routes. Use apps/docs for product documentation. Kit packages such as @repo/auth and @repo/database are available for a product host you add later — they are not mounted as a dashboard app in this repo. Details: Apps.

Frequently asked questions

What is TurboJet?

TurboJet is a production-oriented Next.js starter kit: marketing and docs apps in this repo, plus shared packages for auth, payments, database, mail, storage, AI, and more — structured for a scalable SaaS codebase.

Which frameworks does TurboJet use?

This kit is Next.js (App Router) in a Turborepo monorepo. It is not a multi-framework (Nuxt / SvelteKit) product.

Is there a SaaS dashboard in this repository?

Not in this checkout. apps/marketing and apps/docs are the runnable apps. Auth, Prisma, and API packages remain so you can host a product app separately or extend the monorepo.

How is TurboJet different from other SaaS boilerplates?

Focus on Indonesian-friendly payment providers (Mayar, Midtrans, DOKU) alongside Polar, bilingual en/id docs and marketing copy, and a clear split between the public marketing host (with Hono API) and shared kit packages.
