Licensing
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.

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.

FAQS
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.
When determining the appropriate membership level, do I need to include only full-time developers? What if my company doesn’t have any?
Can I distribute GreenSock files as a part of my Work Product?
Does Draggable use CSS3 animations or transitions for the motion?
requestAnimationFrame
(when available) for maximum efficiency. See for yourself in Chrome Dev Tools - you should see very snappy performance in the timeline. Many other tools like jQuery UI use top/left properties for positioning which don't generally perform as well. These tools have been fully "GreenSocked" so performance is smoking fast, just like the core tweening engine.
Will the bonus plugins suddenly stop working when my membership expires?
Does Draggable have any dependencies?
The only dependency is on GreenSock's core. There are no dependencies on jQuery or any other libraries, although they work great together.
Where do I get LoaderMax?
LoaderMax is included in the main AS3 GreenSock download zip.
