Deadlines are looming.

You need to impress the client with eye-catching animations that perform well on every device, or maybe you're building a sophisticated UI that calls for buttery-smooth draggable elements that flick and glide naturally to precise locations you define. You're not looking for a simplistic jQuery plugin that was slapped together in someone's free time - you need professional-grade, reliable tools. You've come to the right place. We've spent crazy amounts of time obsessing about code so you don't have to.

“ GSAP is just miles and miles ahead of any animation library out there. Great work! ”

Adam Alicki

“ GreenSock has encouraged me to play with the code, to dream up new and exciting things to do. ”

Robert Anthony

“ It's shocking the @w3c didn't use @greensock as a model of how to do animation via code. Did they even ask animators what they use? ”

Elliot Geno, @ElliotGeno

“ GSAP was a revelation for me to be compared with the introduction of jQuery ”

Jan Paepke, @janpaepke

“ Aside from GreenSock’s laser-focused attention to detail, GSAP is fast, reliable, flexible, exceptional value (read: free in most cases) and, very importantly, supported. ”

Chris Gannon

“ Spent today converting an animation to pure CSS, and then into GSAP. GreenSock was an order of magnitude easier. Love it. ”

Tristan Mugford, @tmugford

“ @greensock it’s a great library that many people love, and I know you care deeply about performance :) ”

Paul Lewis, ‏@aerotwist

“ I think I love GreenSock as much as bacon. ”

Nick Zwinggi

“ GSAP and CSS Transitions: I've done both, and its like comparing an F16 to a horse. Take like 10 minutes to try. ”
