Best open-source alternatives to Adobe After Effects

Graphite is an open source graphics engine and editor focused on 2D content creation. It started as a vector editor and is being expanded into a broader creative toolbox that combines vector, raster, and node-based workflows in a single nondestructive environment. The project is aimed at artists, designers, and graphics programmers who want a modern alternative for tasks like illustration, compositing, painting, and desktop publishing. The README emphasizes that the software is in alpha, community-built, and designed to evolve into a comprehensive all-in-one creative platform.

Lottie Open Studio is an open-source, browser-based animation editor focused on creating and editing Lottie animations. It is aimed at users who want to work with vector animations directly in the web browser, with tools for importing SVGs, arranging layers, animating properties on a timeline, and exporting to standard Lottie JSON. The repository also includes a companion CLI utility for converting Lottie JSON files into animated GIFs. The project emphasizes a development workflow that can run locally via helper scripts or in Docker, and it includes live preview integration, comparison mode, and a growing set of animation features under active development. The overall toolkit is intended to serve both interactive editing and command-line conversion use cases.
