Using a Custom Subdomain

Requires Pro Standard or higher

Carrd sites can be published to URLs, custom domains, and custom subdomains. To publish a site to a custom subdomain (of a domain you own), follow these steps:

  1. Click Publish

  2. Set URL to Use my own domain.

  3. Enter the subdomain name exactly as you want it to appear in the address bar (eg. subdomain.domain.ext).

  4. Scroll down a bit to locate the site's target IP, then add the following host record to the domain (usually via your domain provider):

    • An A record pointing subdomain to the first target IP address shown (eg.
    • An A record pointing subdomain to the second target IP address shown (eg. yyy.yyy.yyy.yyy)
  5. Back at Carrd, click Publish Changes

  6. You're done ... almost. Your subdomain now needs to initialize, which is an automatic process that can take up to an hour to complete (though it's usually a lot faster than that). Once initialized, you'll be able to access the site using the custom subdomain you just set up (and do so via SSL). Note that if you're using Cloudflare, be sure to also follow these additional steps.

    Note: If your dashboard still lists the subdomain as "(initializing)" after an hour, please refer to the troubleshooting page or simply get in touch for assistance.
