The Chip package has two kinds of licenses: open source and commercial.
Open Source License
The open source license is designed for you to use Chip to build open source and personal projects. The Chip open source license is GPLv3. The GPLv3 has many terms, but the most important is how it is sticky when you distribute your work publicly. From the GPL FAQ:
If you release the modified version to the public in some way, the GPL requires you to make the modified source code available to the program's users, under the GPL.
Releasing your project that uses Chip under the GPLv3, in turn, requires your project to be licensed under the GPLv3. If you are okay with this, feel free to use Chip under the GPLv3, without purchasing a commercial license.
The commercial license is designed to for you to use Chip in commercial applications, without the provisions of the GPLv3. With the commercial license, your code is kept propietary, to yourself. If you want to use Chip to develop commercial sites, projects, and applications, the commercial license is the appropriate license.
Buying a commercial license takes a minute. Once purchased, you’ll receive a commercial license PDF and you will be all set to use Chip in your commercial application.
The commercial license is a single-installation license, meaning you may integrate a Licensed Copy into one public-facing ("Internet") or internal ("intranet") web root directory at a time. You may also install and use Chip Billing without limitation for local development and testing purposes.
