For the designers Introduction: What is Rive? Rive is a brand new animation tool and we tested it to try its innovative features that bring in interactivity while keeping good performance. Today we’re using Lottie and we’re comparing it to Rive. Lottie is an After Effects plugin. It allows motion designs to be exported out of After Effects and used in-app with their own JS runtime, an NPM Library. While Lottie is built on top of After Effects, Rive is built from scratch with its own animation software allowing developers to add interactivity to their animations.
