SpriteFlow

SpriteFlow is aimed at indie developers who can design a game but cannot draw every frame of it. You describe a character, choose an animation and export a sprite sheet ready for your engine, with style controls that keep a whole cast looking like it belongs in the same world. It covers the animation set most 2D games need.

• The animation library spans idle, walk, run and jump through attacks, spellcasting, hit reactions, death, climbing, swimming and victory poses.
• Four-direction, eight-direction and side-view output covers top-down games, isometric RPGs and platformers.
• Upload a few reference images and palette locking matches colors, line weight, detail level and proportions across frames.
• Exports include PNG atlases with JSON or XML, individual frames, GIF and APNG, with extras such as Unity animation controller presets and Godot AnimatedSprite resources.
• Pixel art at 8-bit, 16-bit and 32-bit detail levels sits alongside cartoon and anime styles, at sizes from 16x16 up to 512x512.

It is a strong fit for solo developers, game jam teams and prototypers who need consistent art quickly, and you can start for free, with each tool showing its credit cost before generating. A practical tip: lock your palette and reference images before generating your first character, so every later sprite inherits the same look.
