All of our licences allow use on staging and/or development domains without counting towards your site activations limit. However, your domain name must reflect one of the allowed TLDs or Subdomains.
These top-level domains are considered dev or staging:
Subdomains that are considered as dev or staging:
stagingN.* (SiteGround; N is an unsigned int)
*.staging.wpengine.com (WP Engine)
Additionally, if your domain is localhost (with any port), it will also be treated as a localhost domain.
If your domain isn’t in the list, and it is not viable for you to change it, just send us a message and we’ll see what can be done.
