FAQS

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.

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) to resell to their customers, they would need to get their own "Business Green" Club GreenSock membership to cover their usage. If your Work Product is given away freely and you're not distributing members-only plugins, you're golden...er, green...er, fine.

Why aren't the bonus plugins hosted on a CDN?

Putting them on a CDN would remove one of the primary reasons for joining Club GreenSock, the very thing that enables ongoing support and development. Not a very good business move.

I don’t want to pay annually. Can I get a permanent license that never expires?

Absolutely. Click the "permanent" checkbox under the "Business Green" membership on the Club GreenSock page.

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.

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

In our support forums.

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.
