Standard "No Charge" GSAP License
I. DEFINITIONS
“GSAP License” means the terms and conditions of this GSAP Software License Agreement.
"GSAP Products" means any Software made available at gsap.com (https://gsap.com) or any successor sites, including but not limited to the GSAP animation library and related plugins, tools, or extensions.
"Permitted Uses" means the implementation and/or use of GSAP Products on any website, web application, or digital interface by any person or entity (which may include, for clarity, those of companies that compete with Webflow in other areas of business).
"Prohibited Uses" means any implementation and/or use of GSAP Products in tools that allow users to build visual animations without code that encourages, induces, or materially assists in creating a solution that competes with Webflow’s visual animation building capabilities.
"Competitive Products" means any software, tool, or service that enables users to create, edit, or manage animations through a visual interface or builder similar to Webflow (https://webflow.com).
II. GRANT OF LICENSE
Subject to the terms and conditions of this GSAP License, Webflow grants you a non-exclusive, worldwide license to use, reproduce, display, and implement GSAP Products solely for Permitted Uses.
III. RESTRICTIONS
You may not:
Use any GSAP Products for any Prohibited Uses without prior written consent;
Reverse engineer any GSAP Products for the purpose of creating Competitive Products;
Remove or alter any proprietary notices or branding from GSAP Products.
IV. OWNERSHIP AND INTELLECTUAL PROPERTY
All intellectual property rights in GSAP Products, including but not limited to copyright, patents, trademarks, and trade secrets, remain the exclusive property of Webflow. This GSAP License does not transfer any ownership rights in GSAP Products to you.
V. TERMINATION
Webflow may terminate this GSAP License and revoke your access in its discretion if you fail to comply with any of these terms and conditions. Upon termination, you must cease all use of GSAP Products and destroy all copies in your possession.
VI. MISCELLANEOUS PROVISIONS
General: This GSAP License is incorporated into and subject to Webflow’s Terms of Service available here (https://webflow.com/legal/terms) ("Terms of Service"). In the event of any conflict or inconsistency between this GSAP License and the Terms of Service, the terms of this GSAP License shall govern in relation to your use of any GSAP Products.
Amendments: Webflow reserves the right to update or modify this GSAP License at any time by posting the revised terms on this website, provided that any such updates or modifications shall not result in any material degradation to the security, integrity, or functionality of any GSAP Products. You understand and agree that your continued use of any GSAP Products after such revisions to this GSAP License constitutes your acceptance of this GSAP License as revised. If you do not accept the revised GSAP License, you are prohibited from using versions of the GSAP Products released after the effective date of the revised GSAP License (as well as any updates made to previous versions). Notwithstanding, you may continue using previous versions of GSAP Products under the applicable terms licensed to you prior to the effective date of the revised GSAP License (for clarity, excluding any updates made thereto).
No Waiver: Failure of Webflow to enforce any provision of this GSAP License shall not constitute a waiver of future enforcement of that or any other provision.
FAQ
Is it acceptable for AI tools like ChatGPT, Cursor, Lovable, Webstudio, etc. to generate GSAP code?
Absolutely! AI-generated code is not a "Prohibited Use".
What if a WordPress plugin or theme or other niche tool allows users to create GSAP-driven effects through a visual interface? Is that prohibited?
We want to encourage developers to build on top of GSAP, including visual tools that don't directly compete with Webflow's rich animation-building capabilities. If you are not sure if your product might be considered a "Prohibited Use", feel free to contact us (https://gsap.com/contact) so we can talk through it!
Can I really use GSAP in commercial projects without paying anything?
Yes, really! Commercial usage is covered under the standard license. All of GSAP including the plugins that were formerly "members-only" like SplitText (https://gsap.com/docs/v3/Plugins/SplitText/) and MorphSVG (https://gsap.com/docs/v3/Plugins/MorphSVGPlugin) can be used in commercial projects at no charge. Enjoy! 💚

- 이 예제에서는
- InfiniteGrid는 각 항목이 화면 경계를 넘으면 extraX·extraY를 타일 크기만큼 바꿉니다. 드래그·wheel과 포인터 시차가 같은 화면에 결합됩니다.

직접 해보기
대각선으로 여러 타일을 이동한 뒤 클릭·탭과 키보드만으로 같은 항목을 찾습니다.
살펴볼 변화반복 경계의 틈과 탐색 대안을 확인해야 합니다. destroy의 리스너 제거와 RAF 종료도 별도로 확인해야 합니다.
