Keyframe - 2D Skeletal Animation

Keyframe.it is a 2D skeletal animation tool designed for creating game-ready sprites. It lets you build rigged characters with bones, meshes, and keyframe animations directly in your browser. The tool features weighted mesh deformation, inverse kinematics (IK), spring physics, and clip management - making it ideal for indie game developers and animators who need production-quality sprite rigs without leaving their browser.
