Hi there! I'm Matt Perry, creator of Framer Motion.
Motion One is my side-project where I experiment with ways to make native browser animation APIs more powerful and easier to use.
It's designed to package all the power and performance of native browser animations in a simpler API, while also extending its capabilities to offer new features like timelines, animation functions and springs.
It's free for everyone to use under the MIT license. Plus, many of the techniques I figure out in Motion One make their way into Framer Motion, like its hardware accelerated animations and scroll animations. With more to come!
