WordPress is published under the GPL, the GNU General Public License. And the GPL has one characteristic that decides everything that follows: whatever is derived from a GPL program is also GPL. Since WordPress themes and plugins rely on WordPress code, they inherit the license.
In practice, this means that the code of a WordPress theme or plugin can be used, studied, modified, and redistributed, even by someone who isn’t the author. That’s what makes the catalog possible.
What you can do
- Use it on as many sites as you want, yours or your clients’. The GPL doesn’t limit installations.
- Modify the code for whatever you need.
- Deliver it to a client along with the site you built.
What the GPL doesn’t cover
Here’s the part that causes confusion, and it’s worth understanding before you buy:
The author’s technical support isn’t code. It’s a service the author sells alongside their license, and it doesn’t travel with redistribution: you don’t get access to the manufacturer’s support channel, which is why the price is a fraction of the original.
That doesn’t mean you’re left without support. These are two different things: the author’s support answers for their own product, and Ultrapack support is our own, in your language, and covers any item in the catalog: installing, updating without losing settings, resolving a conflict between plugins. Whoever answers knows the entire catalog, not just one product.
A service hosted on the author’s server isn’t covered either. A plugin that queries the manufacturer’s API to work depends on that service, and the service has an owner. That’s why some items require a real activation. The scenarios are covered in My license won’t activate.
Images, fonts, and icons in the package may have their own license, separate from the code’s GPL. A demo photo can rarely be used on the final site.
Updates: how it works without the author’s key
The author’s automatic update usually goes through their server, requires their key, and doesn’t need any additional plugin. What handles this on our end is the Ultrapack Auto Updater: new versions reach your WordPress dashboard through the catalog, without depending on that channel.
Why this matters to you
Because it changes what you should expect. You get the complete item and the updates; you don’t get the author’s support. For anyone who knows how to handle their own environment, or who has a place to test, it’s the best path. The full positioning is covered in About us.
