Progress-up is a gratis, free and source is fully open; however, if you are using the library for commercial use a license might make sense.
Open source license
It is MIT licensed. Which means you are free to do anything you want with it.
Please find the key points of the commercial license below. If you have any questions, please contact us.
Commercial licenses are priced per team member. A team member is defined as anyone permitted to make modifications to your applications that uses progress-up, whether such person is your employee or a consultant or contractor providing services to you.
You are entitled to receive all updates up to the major version of progress-up as well as later versions if we authorize. But, if you have a v1 license, that is valid for v2 as well. Just to serve as an example.
Usage in saleable products
You need a team or organization license to use progress-up in a product which end users can be charged for.
Number of products
With the developer license, progress-up can be used as part of a single product. With the team license, progress-up can be used as part of up to 500 products and with the organization license, progress-up can be used as part of an unlimited number of products.
Note: This use is limited within the same company.
progress-up cannot be used in a product offered for sale or for free, where progress-up contributes to the core value of the product being sold. If you like to build something based on progress-up such as a pro WordPress plugin for progress-up, please get in touch.
progress-up may not be used for re-selling, sub-licensing, or sharing purposes, and cannot otherwise be redistributed on its own (even for free).
The commercial License is not limited in time. Once you purchase a license, you can use if for lifetime under the terms of the particular license.
The commercial License is not exclusive and other buyers may purchase progress-up.
