Wix and Joomla don’t allow custom code snippets to be embedded on their sites. They only allow integrations that are part of their official “app marketplace,” which makes it impossible for fully customizable integrations like ours to work. You could embed an iFrame, but we strongly advise against it as it will not be the intended experience for your clients.
Wix or Joomla users can either set up a simple redirect to another page on one of our supported platforms, or they can fully migrate to a supported platform. Our users who have migrated to Squarespace have reported being equally happy with its user-friendly interface.
