LoongBones vs Phluxel

LoongBones is a 2D skeletal animation solution with an online editor and a runtime player. The browser-based editor uses HTML5 and canvas, so it requires no installation, and it can create, modify, and export animation data, images, frame sequences, and other digital assets. Its tools include mesh deformation, bone binding, inverse kinematics, collision, and mesh curve deformation. Imports include PSD files, images, texture atlases, LoongBones projects and data, and supported Spine files. Exports include animation formats, images, sprite sheets, and GIFs, with plugins for additional formats. The runtime plays LoongBones animation data and supports Egret, Cocos, PixiJS, Unity, and Unreal; it is described as open source, free to download, and MIT-licensed. The product also says it supports AI-generated animation and has integrated DeepSeek. A seven-day free experience includes 100M storage and up to 10 projects. Membership costs 19.90 CNY a month or 199.90 CNY a year. The listed platforms include Android, iOS, Linux, macOS, self-hosted, web, and Windows.

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.
