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

is cabbage gross?

Yes.

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.

Does Draggable only work with DOM elements? Can I get it in a canvas-based app ?

Yes, Draggable is just for DOM elements. But the real magic behind all the fluid motion and snapping is InertiaPlugin, and that can be used to tween any property of any object, not just DOM elements. So yes, you can absolutely get this kind of motion in other contexts but you'd need to wire up the actual dragging logic yourself and then fire off an InertiaPlugin tween when the user releases their mouse/touch. InertiaPlugin can even track the velocity of any property for you too (even function-based getters/setters!), so it's quite a powerful tool.

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.

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.

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.

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.
