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.

FAQS
Do I have to purchase a license to use Draggable? Can I use it in commercial projects?
IntertiaPlugin is a membership benefit of Club GreenSock, so you need to sign up to get that. Draggable, however, is included in all the standard downloads and you don't need a membership to get that; Draggable can be used apart from InertiaPlugin as long as you don't need the momentum-based motion. GreenSock's standard license allows you to use GreenSock tools for free in everything except a very specific type of commercial project (if you collect a fee from multiple customers for the app/product/game/site that uses GreenSock tools) which makes it extremely accessible and business-friendly while providing a small funding mechanism to sustain ongoing support, enhancement, and innovation. The web is littered with abandoned “open source” projects, but GreenSock has a years-long track record of commitment to the platform. This unique licensing model is a key component of its sustainability. If you charge multiple customers a usage/access/license fee, please simply sign up for a “Business Green” Club GreenSock membership which comes with a special commercial license granting you permission to do so. Click here for details. Joining the club also gets you members-only bonus plugins, utilities, update notifications, and more.
Does the JavaScript version of GSAP use CSS3 transitions to deliver even better performance (with help from the GPU)?
CSS3 transitions have some significant limitations that make them unworkable for a serious animation platform. They don’t provide precise controls over the timing or easing. They’re great for simple effects but the GreenSock Animation Platform delivers extremely precise rendering, so you can do things like pause() and reverse() an animation anytime or skip to a specific time and play from there, etc. Try creating a CSS3 transition that uses an elastic.out or slow motion ease and then jump to 0.72494-seconds into a 2-second transition and pause() only to resume() later. It’s impossible from what I understand. So no, the platform doesn’t make use of CSS3 transitions. However, it is highly optimized for performance. See the detailed cage match where GSAP battles CSS3 transitions where there’s a detailed comparison in several categories.
How do I get a license?
Will the bonus plugins suddenly stop working when my membership expires?
Do I need to worry about garabage collection in the JavaScript version of GSAP? What happens when a tween finishes?
No need to worry. Tweens and timelines are automatically made eligible for garbage collection (gc) when appropriate (typically when they finish but if you maintain a reference to an instance so that you can restart it later, for example, it won’t be gc’d out from under you). Basically the system manages gc for you and generally cleans up after itself.
