Aseprite extensions
Free Aseprite extensions, including a normal-map generator that reads layer groups instead of a height map.
Pixel-art tools shipped as a gift, not a store. The interesting one is the normal-map generator: it looks at how layers sit in a group instead of baking from a height map. First-party, free, playable in Aseprite.
