Designer Powerup addon offer unlimited staging/localhost licenses and do not count against your license limit.
Here’s a list of all the subdomains/TLDs that are considered as staging by our system:

You cannot manually define a domain/URL as staging. If you are using a staging URL that is not included/whitelisted in the above list, send me an email and we’ll sort it out.
