# Deploy a v0 app outside Vercel, from your AI agent, over MCP

Your app built with v0 is a Next.js app, and it can live somewhere other than Vercel. Your AI agent takes it over from GitHub and, connected to while over MCP, deploys it in France, with commercial use allowed from day one.

## Prerequisites

- A v0 app, synced with GitHub (source 1). Your agent clones the repository to your computer.
- An AI agent that works in a terminal: Claude Code, Codex, Cursor or Gemini CLI.

## Step 1: Give your agent these instructions

Open your agent in your app's folder, and paste these instructions into it:

```text titre="Instructions"
Connect to while with my account (while.sh/agents), then deploy my app.
```

Without an account, your agent deploys your app as a trial, in one request. To keep it, open the link it gives you and create your account.

With your account, your agent adds while's MCP server itself. If it asks you to, restart it. On the first call to while, a page opens in your browser. In Claude Code, if it doesn't open, type /mcp, choose while, then Authenticate. On that page, choose your app, or "A new app", then click Authorize.

## Step 2: Open your app

Your agent gives you your app's address, for example `https://mon-appli.while.cloud`, over HTTPS.

## What your agent does

It writes while.yaml at the root of your app:

```yaml titre="while.yaml"
apiVersion: while/v1
project: mon-appli
services:
  - name: web
    port: 3000
    health:
      path: /
    build:
      args:
        NEXT_PUBLIC_SUPABASE_URL: https://abcdefgh.supabase.co
        NEXT_PUBLIC_SUPABASE_PUBLISHABLE_KEY: eyJhbGciOi…
```

Your Next.js app is built at every deployment, then started with `next start`. The public values, the ones that start with `NEXT_PUBLIC_`, are passed at build time, when Next.js writes them into your pages (source 3). Your server's secret keys are entered in while: your app receives them, and your agent never sees them.

## Share with a customer, protected by a password

> You, to your agent: Open the app to our customer, with a password.

Your agent makes the app private, then, on the app's page in while, you create a link valid for 1, 7 or 30 days, with a password your agent will never see.

## Restrict your app to your colleagues

> You, to your agent: Restrict the app to people in the company.

Your agent adds two lines to the service:

```yaml titre="while.yaml"
    access: internal
    email_domains: [acme.com]
```

Once your Google Workspace or Microsoft 365 is linked to while, on the Pro plan, your colleagues open it with their usual account, with no sign-in page to write.

## Move to your own domain

> You, to your agent: Put the app on app.acme.com.

Your agent declares the domain, you add the DNS records it gives you, and the HTTPS certificate follows.

## Bring your data back to France

> You, to your agent: Move our tables into a PostgreSQL database in while.

Your agent declares a PostgreSQL database, backed up every day, copies your tables into it, and writes the small API that serves them to your app.

## See a new version before you deploy it

> You, to your agent: Show me the new version before you deploy it.

Your agent opens a preview, at its own address. If your database is in while, the preview also has its own data. You look at it, then your agent puts it into production.

## Go back to the previous version

> You, to your agent: Go back to the previous version.

In the 30 minutes after a deployment, the previous version comes back in a second. After that, it takes a few seconds. Once the previous version is back, your agent reads what broke in while's logs, fixes it and deploys again.

## Questions

### Can I keep editing my app in v0?

Yes. v0 pushes its changes to a branch of your GitHub repository (source 1): once the branch is merged, your agent deploys the latest version.

### Can my app be commercial?

On while, it can be from day one. Vercel's free plan, Hobby, is limited to personal, non-commercial use (source 2).

### What about my Supabase or Neon database?

Your app can keep it, once its internet access is opened and approved. To have everything in France, your agent moves your tables into a PostgreSQL database in while.

### Where is my app hosted?

In France, by Nextmap, a French company.
