Usage in 100% free apps, games, sites, and other software even if you charge a fee to develop these products
This includes advertising, internal sites and tools, promotional web sites, free software, and pretty much everything that isn't sold to multiple end users.
Distribution of GreenSock files as a part of your Work Product
Even in open source projects, as long as you leave the source files unedited and recognize that the GreenSock files are subject to their own license. Only BusinessGreen members can distribute the members-only bonus plugins (like ThrowPropsPlugin), and solely to be used as a part of their Work Product.
Usage in web sites or products that require a fee to use or join (NetFlix.com, Ancestry.com, eHarmony.com, etc.)
Usage in games or products that are sold to multiple end users
Usage in games or other apps that use micro-transactions for optional features/upgrades
An example of a micro-transaction is when a user can optionally pay to unlock a certain feature in a free game/app, or a gambling site where the user can technically visit for free, but they may choose to pay to place bets or play games.
Usage of members-only tools like ThrowPropsPlugin, Physics2DPlugin, etc.
One of the nice things about becoming a member is that you gain access to some useful tools that create eye-catching effects, smooth your workflow, and generally save a lot of time and hassle. See the Club GreenSock page for details.
GreenSock's dual licensing model keeps it extremely accessible and completely free for the vast majority of use cases while at the same time providing a small funding mechanism that sustains ongoing support, innovation, and sustainability. The web is littered with abandoned "open source" projects, but GreenSock has a years-long track record of commitment to the platform. Some of the largest companies in the world trust GreenSock tools in their business-critical applications every day. Learn about the "why" behind the GreenSock license here.
