Hi,
Our developer license implies that you install the plugin not for personal use, but as a developer in order to show an ultimate outcome to the client. Such a license is attached only to a development site and can not be used for commercial purposes. Regarding your request: if you have a live site, and you have a license for it, then you can test the plugin work on your dev site which is a subdomain of your live site (for example https://www.dev.domainname.com or https://www.demo.domainname.com). In this situation, the rules of our usual premium license will be distributed for this kind of sites, namely that one plugin can be installed on one domain and its subdomains. So according to our license agreement, we can not give you another license because your dev site is located on a different domain/server.
