A custom domain gives a sandbox a stable address you control, such as demo.example.com. If you later replace the sandbox, move the domain to the new one and your links keep working. Custom domains are available on Workspace plans. The sandbox’s own SandyWP URL keeps working alongside the custom domain.

​
Connect a domain

  1. Open the sandbox, select Site settings, then the Custom Domain tab.
  2. Enter the domain, for example demo.example.com, and select Connect domain.
  3. Add the DNS record SandyWP shows you at your DNS provider.
  4. Select Check DNS. Once DNS resolves, SandyWP routes the domain, issues an SSL certificate, and updates WordPress to use the new address.
If the DNS record already exists when you connect the domain, it goes live straight away.

​
DNS records

Add one of these: Two things stop SSL from being issued:
  • A proxy in front of the record. On Cloudflare, set the record to DNS only (grey cloud).
  • Other A or AAAA records on the same name. Remove them so the domain points only at SandyWP.
DNS changes usually show up within a few minutes, but some providers take longer. Select Check DNS again at any time.

​
SSL

SSL certificates come from Let’s Encrypt and renew automatically. There is nothing to upload or configure.

​
Disconnect a domain

Select the trash icon on the Custom Domain tab. SandyWP stops serving the domain and points WordPress back at the sandbox URL. You can then connect the domain to a different sandbox.

​
Limits

  • One custom domain per sandbox.
  • A domain can be connected to one sandbox at a time.
  • Multisite sandboxes do not support custom domains yet.
  • The API equivalent is PUT /api/app/sites/{id}/domain.
