Skeletal animation. Spine uses a system of bones and joints to manipulate sprites. Each bone controls a part of the character, allowing rotation, scaling, and complex movements without redrawing frames manually.
Mesh deformation. Vertex meshes can be assigned to sprites to deform them dynamically. This enables effects such as stretching, squashing, and twisting of visual elements during animation.
Attachments. Lets you attach additional elements to bones, such as weapons, clothing, or accessories. These attachments automatically follow the animation of their parent bone.
Skinning. Supports multiple skins, or appearances, for the same skeleton. This makes it easy to create character variants without rebuilding the animation from scratch.
Interpolation curves. Offers detailed control over interpolation between keyframes through customizable Bézier curves. Adjust the acceleration and deceleration of movements.
Animation events. Lets you insert time markers into animations to synchronize sound effects, particles, or other actions during playback.
Physics. Includes a basic physics system to simulate natural movements such as swinging, inertia, and bouncing in animated elements.
Cross-platform export. Generates JSON or binary files compatible with the main game engines. Supports runtime libraries for direct integration into projects.
Drawing tools. Includes basic image editing functions for touching up sprites directly, with no need for external software.
Real-time preview. Instantly shows the changes applied to the animation while you edit.
Scripting. Lets you automate repetitive workflow tasks with scripts.
Layer system. Organizes visual elements into separate layers for hierarchical management of animation components.

Spine was developed by Esoteric Software, a company founded in 2013, and its first public version was released that same year. The program is written mainly in Java, which allows it to run on Windows, macOS, and Linux. Over the years it has received constant updates that have added new features such as the physics system, rendering improvements, and support for more game engines.
