Our Mosaizer CLI is equipped with a rich set of possibilities. Since the GUI version is extremely packed with features, the CLI versions seems a bit bleak. But it can make a giant mosaic in less than the time it takes Mosaizer GUI to make one. And it can seamlessly replace one picture in the mosaic result with a new one. This makes the CLI version very popular because it allows for interactivity with website users. A truly unique CLI in many aspects.
