# Custom Domains

> Set up a professional domain name for your deployed product.

After deploying your product, it is available at a Vercel-provided URL (something like `your-product.vercel.app`). You can set up a custom domain (like `app.yourbusiness.com`) for a more professional appearance.

## How to set up a custom domain

Custom domain configuration is done through your Vercel account, where your product is hosted. Transmuter provides a step-by-step guide within the deployment screen.

<Steps>
  <Step title="Purchase a domain">
    If you do not already own a domain, you can purchase one from services like Namecheap, Google Domains, Cloudflare, or directly through Vercel.
  </Step>

  {" "}

  <Step title="Open your Vercel dashboard">
    Go to [vercel.com](https://vercel.com) and sign in with the account you connected to Transmuter.
    Find your project in the dashboard.
  </Step>

  {" "}

  <Step title="Add your domain">
    In your Vercel project settings, go to **Domains** and add your custom domain. Vercel provides the
    DNS records you need to configure.
  </Step>

  <Step title="Update your DNS records">
    Go to your domain registrar (where you bought the domain) and add the DNS records Vercel provided. This typically involves adding a CNAME record.

    <Note>
      DNS changes can take up to 48 hours to take effect worldwide, though most changes propagate within a few minutes to a few hours.
    </Note>
  </Step>

  <Step title="Verify and enable SSL">
    Once DNS is configured, Vercel automatically verifies your domain and provisions a free SSL certificate, so your product is accessible via HTTPS.
  </Step>
</Steps>

## Common domain configurations

| Setup           | Example                | Best for                                  |
| --------------- | ---------------------- | ----------------------------------------- |
| Root domain     | `yourbusiness.com`     | Main product or company website           |
| Subdomain       | `app.yourbusiness.com` | Product app alongside an existing website |
| Separate domain | `yourproduct.com`      | Standalone product with its own identity  |

<Tip>
  If you already have a website at your root domain, using a subdomain like `app.yourbusiness.com`
  is the easiest approach -- it does not affect your existing website.
