Spine
What Spine is
Spine is a 2D animation tool focused on game animation, combining an editor for creating animations with runtimes for using them in games. It creates skeletal or cutout animation by attaching images to bones and animating those bones. Rigging and animation capabilities include inverse kinematics, paths, skins, meshes, free-form deformation, weights, a dopesheet, a graph editor, and runtime preview. Exports include documented JSON and binary animation data, animated GIFs, PNG or JPEG image sequences, AVI or QuickTime video, and texture atlases or spritesheets. Official runtimes support toolkits including Unity, Unreal Engine, Godot, iOS, Android, Flutter, Phaser, PixiJS, and libgdx; generic runtimes are also listed for C, C++, C#, Haxe, and TypeScript. Spine runs on Windows, macOS, and Linux. The free trial includes Professional features, but cannot save projects, pack textures, or export animation data, images, or video. Essential is listed at $99 a month, and Professional at $449 a month. Enterprise and educational licenses have annual terms, with education options for 10, 25, or 50 computers.
