# Apps inside a project

> A project can hold a Website, a Web app, and a Mobile app side by side — each with its own chat, files, preview, pages, server, and publishing, all sharing one CRM, team, domain, and cloud database.

**A project is no longer one site.** A single ESTAGE project can hold a **Website**, a **Web app**,
and a **Mobile app** at the same time, and you switch between them from a **switcher in the
builder**.

Build the marketing site, the customer portal, and the phone app once — on one set of data —
without wiring three separate projects together by hand.

## Each app is a real, separate build

Ask the AI to change something and it changes **the app you have open**. Nothing bleeds into the
others.

| Per app | What that means |
| --- | --- |
| **Chat history** | Each app has its own conversation with the AI |
| **Files** | Separate codebases — a Next.js app is not your website's React build |
| **Live preview** | The preview follows the app you're in |
| **Pages list** | Each app has its own routes and folders |
| **Server** | The **Server** tab shows *that app's* machine, not the project's main one |
| **Publishing** | Publish each app independently, on its own schedule |

Inspector edits, version history, and settings all follow whichever app you have open.

## What the apps share

The things that should be shared, are:

- The project's **[CRM](/crm/) connection** — one customer list, one product catalog, one set of
  orders behind all of them.
- **[Team members](/project-settings/members/)** and their [roles](/project-settings/roles/).
- The project's **[domain](/domains/)** — put each app on its own subdomain
  (`app.mysite.com`, `store.mysite.com`).
- The project's **[cloud database](/cloud/)** — one backend, read and written by every app.

## Adding an app

On the project, add the target you want — a **Website**, a **Web app**, or a **Mobile app** — and
it appears in the switcher next to what you already have.

- [Mobile apps](/platform/mobile-apps/) require an account with mobile-builder access.
- [Web apps](/platform/web-apps/) are billed per app: dev hours while you build, and a dedicated
  machine once you publish.

:::note
Creating a *new* project starts from a **"What are you building?"** chooser on the
[dashboard](/workspace/dashboard/). Adding a second app to an existing project is the other route
— same builder, one project.
