LibreSprite vs Pix2D

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.

Pix2D is a pixel art, sprite, and animation editor for game art. Its drawing tools include palette and brush controls, layers, blend modes, custom grids, pixel-perfect shapes, text, and onion skinning; it also offers an animation timeline and sprite-sheet export. Pix2D runs in a browser without installation, saving work locally in that browser, and has versions for Windows, macOS, Linux, and Android. Projects use the .pix2d format, with exports including PNG, JPG, SVG, GIF, sprite sheets in PNG and JSON, Aseprite JSON, Godot .tres, Unity .png.meta, and libGDX .atlas. Pix2D is free and released under the MIT License. Its public APIs and plugin system are under development. Desktop and Android versions send anonymous usage events that exclude project files, image content, and identifying information; they also offer opt-in anonymous fatal crash reporting through Sentry. The web build reports crashes locally. The macOS app is unsigned and unnotarized, so Gatekeeper may show a warning on first launch.
