Custom domain

v0 provides all deployments with a unique vercel.app URL, but you can add custom domains to give your applications a professional, branded web address.

Once you have a deployment available, you can add a custom domain directly from the v0 interface:

Step 1: Access the share menu

1. Open your deployed chat in v0
2. Navigate to the share section and open the Publish tab where your deployment is available
3. Look for the "Add a domain" button in the publish menu

Step 2: Choose your domain option

When you click Add a domain, you'll have two main options:

Option A: Use an available .vercel.app domain

• Select from available .vercel.app domains
• These are free and instantly available
• Perfect for testing and development
• Automatically configured with HTTPS

Option B: Add your own custom domain

• Enter your own domain name (e.g., myapp.com)
• Requires DNS configuration with your domain registrar
• Provides professional branding
• Full control over your domain

Configuring your own custom domain

If you choose to use your own domain, you'll need to configure it through the Vercel console:

1. Click "View on Vercel" from the Publish Menu
2. Follow the detailed instructions in the Vercel dashboard
3. Configure DNS records with your domain registrar

For complete instructions on setting up custom domains, including DNS configuration and domain management, see the Vercel documentation on adding domains.
