GreenSock’s standard “No Charge” license is very permissive (it even covers most commercial uses), but “Business Green” Club GreenSock memberships come with a comprehensive commercial license plus time-saving bonus plugins and tools.
Our paid license is only necessary in software that you create using our products that is sold to multiple end users. If you believe that all software should be free then obviously you aren’t selling your own software and you don’t need a commercial GreenSock license. Nothing to worry about.
If you require a license because your free app has micro-transactions or you are building a paid-for service (like Netflix or a game app), it’s really up to you to assess if your revenue will adequately cover the nominal license fee. 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.

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.

- 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 distribute GreenSock files as a part of my Work Product?
Yes, as long as the source files are unaltered (including copyright notices therein). Your customer may use GreenSock tools (including bonus plugins/classes you got with your membership) only as a part of your Work Product. However, if your customer wants to use the GreenSock tools outside of your Work Product or make customizations to your Work Product, they would need to get their own “Business Green” Club GreenSock membership to cover their usage.
- For how long must I maintain my membership?
- 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.
- How much does It cost?
There are several different “Business Green” membership levels based on the number of developers that will have access to the code. All “Business Green” memberships come with the special commercial license. Please see the Club GreenSock page for pricing details.
- How do I get a license?
Just sign up for a “Business Green” Club GreenSock membership at the level that corresponds to the number of developers in your organization. That’s it!
- I don’t want to pay annually. Can I get a permanent membership so that it never expires?
Absolutely. Click the “permanent” checkbox under the “Business Green” membership on the Club GreenSock page.
- 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.
- Can I include GreenSock code in my open source library?
- If I get an annual membership, can I upgrade to a permanent one later?
Sure. When you upgrade, the most recent annual membership fee will be refunded (1 year’s worth of fees). Contact us to request an upgrade.
- 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. Please read our post Licensing: “Free” != Better to understand why. There is also an article on why a “Business Green” Club GreenSock membership makes a lot of business sense here.
