Licensing Options

GreenSock’s standard "No Charge" license is very permissive (it even covers most commercial uses), but "Business Green" members get a comprehensive commercial license plus time-saving bonus plugins and tools. Why isn't GreenSock MIT-licensed? Find out here.

Benefits

Most developers find that GSAP’s workflow features alone save them so much time that the license pays for itself literally in a matter of days. After factoring in the bonus plugins and the performance boost, the expense quickly turns into profit.

Business License

Our paid license is only necessary in projects that you sell to multiple end users. That's it. Even if you charge your client a million dollars for whatever you create for them, it's fine to use GreenSock tools under the standard license as long as it's a one-off project.

Enterprise Level

We realize that some legal departments can be quite picky and enterprise institutions have a unique set of needs, so if our standard "BusinessGreen" license isn't quite what you need, check out our Enterprise Licensing page.

What's Covered?

License Standard Business

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.

Business-Friendly

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.

FAQS

Will the bonus plugins suddenly stop working when my membership expires?

Nope. We don't inject any "phone home" code that tracks usage or causes the plugins to suddenly stop working on a certain date. Hopefully our tools prove so valuable and profitable to you that you'll gladly renew every year to keep getting access to the goodies.

What if I develop a commercial product for my client who will be the one selling the product? Who needs the “Business Green” membership?

To make it easier on GreenSock customers, the policy is that the development company needs to maintain a valid “Business Green” membership. If, for example, Company A develops a Work Product that uses TweenLite/Max and sells it to Company B who will be licensing it to end users, Company A must maintain a “Business Green” membership. Company B would not be required to have a membership. If, however, Company B prefers to maintain a membership instead, that is perfectly acceptable as long as it wouldn’t reduce the club level, meaning if the development company has 20 developers and Company B has 1 developer, it wouldn’t be fair to circumvent the terms by only having Company B get a single developer membership. A 20-developer membership would be required.

Why not give the code away for free?

We firmly believe this licensing model ultimately delivers a superior end product and serves the community better. Open source projects with no funding mechanism typically stagnate and become obsolete. Our goal with this licensing model is to keep the tools extremely accessible while putting in place a mechanism that funds continued support, innovation, and bug fixes. Read The "Why" Behind the GreenSock License for details.

For how long must I maintain my membership?

You may cancel anytime. You'll simply lose access to updates to the bonus plugins/tools and if you're a Business Green member, your commercial license would expire at that point. You should keep it active as long you are selling/licensing your product to multiple end users. Work Products that you sold in the past do not suddenly fall out of compliance when your membership lapses – you just can't continue to sell products that use GreenSock tools after your membership expires. If you don't want to worry about the license expiring, you can simply get a permanent license. Oh, and we don't add any code into the members-only plugins that would make them suddenly stop working when your membership expires. They'll continue to work.

Is there a limit to the number of projects I can use GreenSock tools in as a “Business Green” member?

No. The commercial license that comes with “Business Green” Club GreenSock memberships applies to an unlimited number of apps/sites/software/games that your organization sells while the membership is active (see the license agreement for specifics). Please be sure, however, to get the appropriate membership level based on the number of developers associated with your organization.

Can I include GreenSock code in my open source library?

Absolutely, but there are a few caveats: You may not include any of the members-only bonus plugins/classes in your open source tool (for obvious reasons) and you must clearly represent that the GreenSock code uses its own separate licensing model. We encourage the use of GreenSock tools to empower other open source tools.

Where can I get the CDN URLs for the current version of each tool?

Check out the GSAP Overview on the docs homepage. It makes it super easy to see which tools are hosted on the CDN and copy the URLs to your clipboard. You can also get a full list at CDNJS.com.

When determining the appropriate membership level, do I need to include only full-time developers? What if my company doesn’t have any?

You must include all freelancers, consultants, subcontractors, etc. in addition to full-time developers.
