  • Lunacy is a life-saving software. One of the things that I love is the content library. It has so many vectors that are free to use and can be used for commercial. Also, I can save the project in .jpeg or .png, or any other graphic file format.

  • I think Lunacy is one of the most innovative "not headline-grabbing" pieces of software in the last decade. The only fact that the team managed to create a version for all three major desktop operating systems (Windows, Linux, and macOS) is exceptional.
