Phluxel vs SpineBones

Phluxel is a Windows application for adding animated effects to pixel art and exporting seamless loops. It creates rain, fire, snow, water, wind, and glow through rules written in the Phlux language, which describes how cells respond to neighbors using math, conditions, and scatter. The editor includes a cheat sheet, autocomplete, and live preview. Global rules compile to GPU shaders for real-time playback, while per-cell logic can run through a CPU interpreter. Phluxel imports PNG, JPG, BMP, animated GIF, and WebP files with smart downscaling and palette lock. Exports include GIF, PNG sequences, APNG, MP4, sprite sheets, and palette-locked files. It includes 90 starter scenes across eight groups and 128 rule templates. Free is for personal, non-commercial work; Pro grants commercial use. Free exports are watermarked and limited to a 128×128 grid, 1024px, and 300 frames. Pro costs 19.99 USD once.

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.
