Glaxnimate 0.6.0 is out and can now be deployed for Linux, the MS Store and macOS thanks to being fully integrated into KDE’s build system.
It has been translated to 28 languages, boasts a smoother animation workflow, and comes with better support for importing and exporting to SVG, among many more marvelous things.
Originally it was designed to create Lottie animations.
Edit: Which, and to answer the original question, have nothing to do with what Krita does at all.
