LibreSprite is aseprite but free.

It has a Windows and Linux installer, but not for mac.

If you want to get it on mac you have to compile it from source.

But now you get it without compiling!

THE DEVELOPERS OF LIBRESPRITE RELEASED A VERSION FOR MAC THAT IS IN BETA NOW, DOWNLOAD IT HERE: https://libresprite.github.io/#!/downloads

LIBRESPRITE MAC WILL NOW USE THE OFFICIAL VERSION OF LIBRESPRITE.

THANK YOU.
