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

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.

Can I try the bonus plugins before I buy?

Absolutely! We would love for you to see for yourself how powerful and helpful these tools are. We created a starter template and video to show you how to use fully-functional trial versions of Club GreenSock plugins on CodePen.

Can I include GreenSock code in my open source library?

Absolutely, but there are a few caveats: You may not include any of the members-only bonus plugins/classes in your open source tool (for obvious reasons) and you must clearly represent that the GreenSock code uses its own separate licensing model. We encourage the use of GreenSock tools to empower other open source tools.

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.

Why not give the code away for free?

We firmly believe this licensing model ultimately delivers a superior end product and serves the community better. Open source projects with no funding mechanism typically stagnate and become obsolete. Our goal with this licensing model is to keep the tools extremely accessible while putting in place a mechanism that funds continued support, innovation, and bug fixes. Read The "Why" Behind the GreenSock License for details.

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.

For how long must I maintain my membership?

You may cancel anytime. You'll simply lose access to updates to the bonus plugins/tools and if you're a Business Green member, your commercial license would expire at that point. You should keep it active as long you are selling/licensing your product to multiple end users. Work Products that you sold in the past do not suddenly fall out of compliance when your membership lapses – you just can't continue to sell products that use GreenSock tools after your membership expires. If you don't want to worry about the license expiring, you can simply get a permanent license. Oh, and we don't add any code into the members-only plugins that would make them suddenly stop working when your membership expires. They'll continue to work.
