LibreSprite vs OPTPiX SpriteStudio

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.

OPTPiX SpriteStudio creates 2D sprite animation data for projects ranging from short animations to game development. Its mesh and bone tools support deformation, and bone influence weights can be calculated automatically. Masking can define permeable overlap areas and effects such as wipes, with adjustable position, size, and shape. A designer can produce sprite animation data alone using the tool. SpriteStudio supports readable XML and compact binary formats, as well as instance and particle effect creation. Listed engine support includes Unity, Unreal Engine 4, and Cocos2d-x; game engine players and an SDK are available free of charge. Export options include PNG, GIF, WebP, AVI, MP4, SSCE, SSAE, Cocos2d-x PLIST, and Corona SDK LUA. It runs on Windows and macOS and requires an always-on internet connection, along with listed hardware and graphics requirements. The free Starter License is limited to companies with prior-year sales under JPY 10 million and has feature restrictions and attribution requirements. The Professional License costs ¥93,500 a year. A one-month trial includes SpriteStudio Ver.7 features but not SpriteStudio 5.
