LibreSprite vs Phluxel

LibreSprite is a free, open-source program for creating and animating sprites. It provides real-time animation previews and onion skinning, with sprites arranged in layers and frames. Users can edit multiple sprites at once, draw in tiled mode, and use pixel-precise tools such as filled contour, polygon, and shading mode. The program includes ready-to-use palettes and supports creating custom ones. Listed export formats include PNG, GIF, JPEG, BMP, PCX, TGA, ICO, FLI/FLC, WebP, and ASE; sprite-sheet export is also listed. Scripting methods cover loading palettes, cropping and resizing sprites, and saving them. LibreSprite is available for Windows, macOS, Linux, and Android. The project developed independently after originating as a fork of an Aseprite commit covered by GPL version 2. Version 1.0 is listed as supported, and the project security page reports no published advisories. The plan is free.

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.
