Best open-source alternatives to Adobe After Effects

Graphite is an open source graphics editor and engine aimed at covering a wide range of 2D creative work. It began as a vector editor and has grown into a more general-purpose tool that combines vector and raster workflows in a single nondestructive editing environment. The project is positioned for artists, designers, and graphics programmers who want a modern, extensible creative toolbox. Its node-graph core powers user-facing tools for compositing and generative design, with additional planned capabilities including photo editing, motion graphics, digital painting, desktop publishing, and VFX compositing.

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.
