For collaborative animation design and development that works with mainstream design tools, LottieFiles is a top choice. It streamlines the creation of high-quality, small-size animations that can be made interactive and scriptable. The service comes with collaboration tools for managing projects and keeping version histories, and it integrates with other design tools that can dramatically accelerate your design and development work.
Another strong contender is Rive, which is geared for richly interactive motion graphics. With tools like State Machine, Animate Anything and Rive Editor, it's designed to bridge the gap between designers and developers. Rive can animate in real time, and its pricing options are flexible enough to accommodate everything from solo designers to bigger teams.
Modyfi is a collection of tools for creating, animating and editing visual assets. It includes Motion for creating animations, advanced image editing and project collaboration. Its interface is designed to be accessible to people with varying skill levels, thanks to an AI-powered art direction system. Modyfi also offers fast image processing and nondestructive editing, which can speed up your design work.
Last, Figma offers an all-purpose collaborative design, prototyping, development and feedback tool. It's got features like AI-generated UI, auto layout and instant batch editing that are good for both experts and noobs. Figma's integration with other tools and its REST APIs for third-party integrations can help keep design and code in sync, too, and that can help you work more effectively with your colleagues.
