Open Source Animation Software

Lottie is a wonderful library for Android, iOS, Web, and Windows that works by parsing Adobe After Effects animations that have been exported as json with Bodymovin, and then rendering these natively on mobile and on the web! Now you can have beautiful animations without engineers having to recreate everything by hand. Building animations by hand is time consuming, and other animation alternatives like Gifs and Png sequences don’t offer the same flexibility and varied features that Lottie offers. With Lottie, you can achieve exquisite animations exactly how you want, with no additional engineering effort whatsoever.

CSS-Inspiration is a living gallery of modern CSS effects and components that highlights what’s possible with pure CSS and minimal markup. The collection ranges from micro-interactions and loaders to 3D transforms, complex backgrounds, hover states, and text effects, each presented as a small, self-contained demo. Source code is front and center, encouraging developers to study, copy, and tweak snippets for their own projects. Many examples lean on contemporary features—custom properties, filters, blend modes, gradients, and keyframes—serving as both inspiration and a practical cookbook. Because each demo focuses on a single idea, it’s an effective way to learn new techniques without wading through a full framework. The project thrives on experimentation and community interest, making it a frequent reference for designers, front-end engineers, and educators who want visually striking yet lightweight solutions.

View Controller Transitions Library is a collection of iOS7 animation controllers and interaction controllers, providing flip, fold and all kinds of other transitions. With iOS 7 you can easily create custom view controller transitions that can be used in a range of contexts (push, pop, modal, etc.) This project provides a library of custom animations which can be dropped directly into your project. It also has a number of 'interaction controllers' which can be used with any of the custom animations in order to make your transitions interactive. Animation and interaction controllers are entirely independent, this means you can wire up any interaction controller with any animation controller, which is pretty awesome. When you indicate that a custom transition should be used, you provide an animation controller. This class performs the required animation, then informs the framework when it has completed.
