It is standalone, modular, object-oriented and lightweight. Additional plugins are only required for advanced usage.
In contrast to other animation tools, Mashi uses a scene-based timeline. So you are not limited to a timeline divided into dozens of equal frames per second but you can split your timeline into self-contained and independent scenes at will.
The toolkit has an automated preloader which loads images used in advance for a better user experience.
Mashi has a "controls" module which provides buttons like "play" and "pause" with their logics and it works in all major browsers including mobile and tablet.
