The Envato Marketplace which exclusively sells the WP Cloud Plugins offers Regular License (terms & conditions) and Extended License (terms & conditions) for the plugin.
Both Licenses are a 1-time purchase, single domain and come with unlimited updates & 6 months of free support.
Regular License vs Extended License
You will need an Extended License when the plugin is used on a section of your site which is accessible by paying users (e.g. via memberships, subscriptions, product purchases, etc...). If the plugin is only used on a free accessible section on your site, a Regular License is the one you are looking for.
The most important thing is that the Extended Licence is a commercial licence. So if your company makes money by (for example) providing services that use the WP Cloud Plugin modules as part of the service, then the Extended Licence is also required. If your service is free, the regular license is perfectly fine.
If it is found that a regular licence is being used on a commercial site where users have to pay to access a site with a WP Cloud plugin module, the licence can be revoked.
Which license for Single site, multiple site, unlimited sites?
The Licenses only covers the usage in one End Product, which means that you will need a separate license for each site when the sites contain a different End Product.
Examples:
- When the main site is a global site (.organization.com) for a organization and the subdomains are used by the local departments (newyork.organization.com, london.organization.com)
-> Separate licenses
- When the subdomain (shop.organization.com) is just part of the website on the main domain (.organization.com).
-> A single license
- When the plugin is used both on a live site (.organization.com) and its development/staging environment (localhost, dev.organization.com, .organization.com/staging etc)
-> A single license
- When you want to use the plugin on multiple domains (a-organization.com and b-organization.com). Or when you are using different top-level domains: a-organization.eu and a-organization.com.
-> Separate licenses
- The plugin is used on a section of your site which is only accessible after paying (memberships, subscriptions, product purchases, etc...). This also applies if your company makes money in other ways. For example, if you offer services that use the WP Cloud Plugin modules as part of the service.
-> Extended License
What about development environments?
Localhost, staging and development environments won’t get counted toward the license’s maximum allowed sites if its domain name is clearly a dev or staging site. Here you can find a list of TLDs and subdomains that are considered as dev or staging.
