What is Spine (Esoteric)?

Spine is dedicated 2D skeletal animation software focused on game development workflows. It uses bone-based rigging with mesh skinning and weight deformation, inverse kinematics for posing, a dopesheet for timing, and ghosting for motion visualization, letting animators create efficient, reusable animations from image assets rather than hand-drawing every frame.

Developed by Esoteric Software LLC, a small team based in Tacoma, Washington, since 2013, Spine provides runtime libraries for integrating animations into most major game engines and programming languages. It is sold as a one-time license across Essential, Professional, and Enterprise tiers, with a free trial version available for Windows, Mac, and Linux.
