What it is

Spine is a 2D animation tool focused on making animations for games, with an editor and runtimes for using the results in games. It builds skeletal or cutout animation by attaching images to bones and animating those bones. Rigging and animation tools include inverse kinematics, paths, skins, meshes, free-form deformation, weights, a dopesheet, a graph editor, and runtime preview. Exports include JSON and binary animation data, animated GIFs, PNG or JPEG image sequences, AVI or QuickTime video, and texture atlases or spritesheets. Official runtimes support 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. Its 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; Professional is $449 a month.
