Kinetra2D vs LibreSprite

Kinetra2D is a web-based workspace for rigging artwork, animating 2D scenes and exporting projects for PixiJS. Users can build bone hierarchies, pose characters, edit meshes and control attachment vertices. Animation tools include keyframes, easing, playback, clips and a dedicated timeline. AI animation generation can supply motion starting points for further manual refinement. PixiJS is the only supported export engine; a downloadable ZIP can include skeleton JSON, atlas PNG and JSON files, and sounds for a scene or project. Scenes can be organized in a cloud workspace, with capacity depending on the plan. The Free plan includes three projects per workspace and one scene per project, with community support. Pro costs $12 a month, billed monthly, and includes 50 projects per workspace, 10 scenes per project and up to 50 cloud projects. Team costs $20 a month, billed monthly, with a two-seat minimum; Studio costs $32 a month, billed monthly. Paid tiers start with a no-charge 14-day trial that requires no payment method. Locally saved Animator projects stay in the browser unless users send project data to an account feature.

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.
