Effekseer vs LibreSprite

Effekseer is a free, open-source tool for creating particle effects for games and movies. It exports effects as 2D animations or 3D effects, with runtimes available for Windows, Mac OS X, Linux, iOS, Android, and Emscripten. Included runtimes support DirectX, OpenGL, Unity, UnrealEngine4, and Cocos2d-x; separate downloads also provide plugins or libraries for GodotEngine, RPGMakerMZ, WebGL, DXLibrary, and other listed integrations. Programmer libraries support DirectX 9/11/12, OpenGL, Metal, and Vulkan. The listed available version is 1.80.7. Version 1.80 adds collision settings, UV repetition for tracks and ribbons, movement-aligned rotation, additional spawning options, external-model emission sources, and directional billboarding. It supports direct loading of gltf, glb, obj, geo, and bgeo models. GPU particle simulation and CPU/GPU profiling are preview features that may not be available in all environments. The tool and runtime use the MIT license; texture and effect data use CC-0. Playing effects in a game requires separate runtime or library packages.

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.
