# App

> The main user-facing SaaS application.

The `apps/app` directory contains the core SaaS application built on [Next.js](https://nextjs.org). It wires together authentication, real-time data, AI chat, billing, and collaboration.

## Overview

The primary application your users interact with. It splits into authenticated and unauthenticated route groups, so public pages and protected dashboards coexist in the same codebase.

```bash theme={null}
turbo dev --filter=app
```
