I’m a seller on Envato Market (CodeCanyon) so I’m bound to their license system. If you want to read more about their licensing, please go and read the information about the Standard License. They even have a FAQ page that should answer most of your questions as well.

The questions that I get most often are the following ones:

Do I need a license for every single domain?

The short answer is yes. Even the extended license does not allow you to use it on multiple domains. As far as I know, Envato has no plans to changes this in the future.

Do I need multiple licenses if I’m on a multisite?

• Yes, you need multiple licenses if every site on your multisite has its own domain name.
• No, you don’t need multiple licenses if you’re using subfolders or subdomains for the multisites.

Do I need multiple licenses if I use it on a test domain (like a staging environment)?

Technically yes, if the test domain differs from your live domain name. Otherwise no.
