Use your own address, like `app.yourcompany.com`, instead of `your-project.b4a.run`.

## Add a domain

1. Publish your project.
2. In Production, open the **Domains** tab.
3. Enter your domain.
4. Copy the **CNAME** record shown and add it in your domain provider's DNS settings.
5. Click **Verify now**.

The status changes to **Issuing SSL** and then to **Ready**. HTTPS is set up automatically.

:::hint{type="info"}
DNS changes can take from a few minutes to a few hours to propagate. If verification fails, wait and try again.
:::

Your `b4a.run` address keeps working after you add a custom domain.
