Adding secondary domains to a Buttonizer instance is possible for all users on our Agency plans.
Per site it is possible to add up to 50 secondary domains. This means that it will be possible to add other domain names or other subdomains to your site.
All sites will show the same widgets as on the primary domain. This way you are able to configure a development or production environments using the original instance. No more migrations or creating different sites!
Good to know: Just like your primary domain, a secondary domain is locked to it's domain as well. You can read more about this here.
