Charios vs Spritix

Charios is a browser-based 2D character animation tool that applies motion-capture clips to layered character art. It can detect alpha islands in an image and export the body parts as transparent layers for rigging. Characters use a fixed 17-bone humanoid skeleton, and users can retarget bundled motion clips or import their own.bvh or.fbx files. A 3×3 animation-check grid displays nine clips at once. Exports include animated GIFs, PNG sequences, JSON, Unity prefabs, Godot scenes, and Unreal Engine actors; files are bundled and downloaded in the browser. Charios says character art stays in the browser during export. The editor requires a modern desktop browser with WebGL 2, while mobile supports project viewing and animation previews only. The Free plan includes three active projects, 30 credits per month, and 13 bundled motion-capture clips. Pro costs $20/month, Studio costs $45/seat / month, and Lifetime costs $50 one-time. Pro and Studio list unlimited projects. Charios describes its audience as indie game developers, solo artists and animators, game-jam teams, and marketing or design teams.

Spritix is a web tool for turning one full-body character image into 2D game animations. It generates Idle, Walk, Run, Jump, and Attack actions from an uploaded PNG, JPG, or WebP image up to 10 MB. After approving an action, you can export a sprite sheet PNG, animated GIF, Atlas JSON, or ZIP containing individual PNG frames. Browser editing provides trimming, Perfect Loop, start-frame rotation, speed from 0.5x to 2x, and frame-count and size controls without using credits. Saved generations remain as immutable versions, and returning to an earlier version is free. The credit cost appears before generation, while failed generations restore consumed credits automatically. Spritix lists Unity, Godot, GameMaker, Phaser, Cocos Creator, Aseprite, PixiJS, and Tiled as compatible with standard exports, without implying endorsement. Atlas JSON may require conversion for some engines or importers. A free plan provides 20 credits monthly; paid plans start at $12 a month.
