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

Who uses GreenSock tools?

Here are just a few: Google, Microsoft, Dow, Sony, Amazon, Fox, EA, Ford, HP, Adobe, Coca-Cola. To see the great work these and other brands are creating with GreenSock tools, swing by our showcase.

Do I have to purchase a license to use GSAP? Can I use it in commercial projects?

GreenSock uses a very permissive license that allows you to use the tools for free for everything except a very specific type of commercial use (if you collect a fee from multiple customers for the same app/product/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 that sustainability. If multiple customers are charged a usage/access/license fee of any kind, 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, classes, update notifications, and more. Please see the licensing page for details.

Where do I get LoaderMax?

LoaderMax is included in the main AS3 GreenSock download zip.

What if I need to send variables to the server along with my request in a loader?

The first parameter of the various loaders (ImageLoader, XMLLoader, SWFLoader, MP3Loader, etc.) accepts either a simple String URL or a URLRequest. So if you want to pass data to the server, simply construct a URLRequest accordingly, like:

var request:URLRequest = new URLRequest("http://www.yourDomain.com/whatever.php");
var data:URLVariables = new URLVariables();
data.exampleSessionId = new Date().getTime();
data.exampleUserLabel = "label1";
request.data = data;
request.method = URLRequestMethod.POST;
var loader:ImageLoader = new ImageLoader(request, {name:"image1"});

Where can I report a bug, feature request, or rave about my tweening adventures with GSAP?

In our support forums.

is cabbage gross?

Yes.

Can I use the JavaScript version of GSAP for canvas objects or 3rd party tools like EaselJS?

You can animate ANY numeric property of ANY JavaScript object – it’s not just for DOM elements. So yes, you can animate canvas objects, EaselJS assets, and pretty much anything JavaScript-related. In fact, GSAP even has an EaselPlugin to make it easier to animate EaselJS properties. If you need to run logic after each refresh (like to redraw things on the canvas), either use an onUpdate on the individual tween/timeline or add a “tick” event listener to the core Ticker that drives the platform.

Which browsers work with the JavaScript version of GSAP?

GSAP itself is pure JavaScript and should work in virtually ALL browsers. GSAP wasn’t intended to solve all browser incompatibilities, but it does implement wizardry for critical features like opacity, transforms (rotation, scaleX, scaleY, skewX, skewY, x, and y), and transformOrigin so those should work in all major browsers even back to IE6. Firefox doesn’t support backgroundPositionX or backgroundPositionY, so those specific properties won’t work but backgroundPosition will for virtually all browsers. There is NOT a predetermined list of css properties that you can tween – the platform will attempt to tween ANY property you pass in. If it is numeric, it will tween it. If it isn’t numeric and it isn’t a recognized special property, CSSPlugin will just set the property to the value you provide (without tweening it). So, for example, if you try to tween to display:"inline", that isn’t a tweenable property but it will still be set accordingly during the tween, so feel free to use that to your advantage.
