In their own words
SpineBones
SpineBones is a free 2D skeletal animation editor for creating bone rigs, keying motion, and exporting animations. Rigging includes hierarchies, re-parenting, grouping, and inverse kinematics. Its timeline supports keyframe insertion, movement, selection, copying, looping, per-key easing, and audio tracks. Slots accept PNG, JPG, SVG, and WebP artwork, with multiple attachments and frame-by-frame swaps. Attachment meshes can be deformed with keyed vertices, and onion skin shows neighboring poses. SETUP stores the base pose; ANIMATE keys position, rotation, and scale. Exports include WebM video, transparent PNG sequences, sprite sheets with atlas data, and portable .sbn packages; legacy .json projects open too. An MCP bridge supports Claude and other MCP clients for rig elements, keyframes, frame-rate changes, and exports. It runs on macOS 12+ and Windows 10+, with no account, licence key, or trial timer.
