Introduction

What is this?

Ship Superfast is a ready-to-use starter for building full-stack apps. It gives you a web app, a mobile app, and a backend — all in one project, all wired together.

You don't have to set up authentication, payments, teams, file storage, or email from scratch. It's already done. Just clone, add your API keys, and start building your actual product.

What's inside

The project is a monorepo — one repository with multiple apps that share code.

apps/web/ — A Next.js 16 website with a landing page and a full dashboard (profile, teams, billing). Uses shadcn/ui components and Tailwind v4.
apps/mobile/ — An Expo 54 app for iOS and Android. Uses HeroUI Native components and Uniwind (Tailwind for React Native). Has the same features as web — profile, teams, billing.
packages/convex/ — The backend, powered by Convex. This is where your database, authentication, API functions, webhooks, and all server-side logic lives. Both apps connect to this same backend.
packages/shared/ — TypeScript types and small utilities that both apps use (like UserRole, TeamRole, and getInitials()).

Features included

How the apps connect

Both apps talk to the same Convex backend. There's no REST API to build or maintain — Convex gives you real-time queries, mutations, and actions that both apps call directly.

                 │  • AI/RAG    │
                 └──────────────┘

Both apps share the same users, teams, and data. A user who signs in on web sees the same teams and billing status on mobile.
