It provides Virtual DOM API for DOM manipulations, UI Components and Scheduler tightly integrated with UI Components.

Kivi API is designed specifically to provide fast bootstrap time (cold start) and fast hot updates, good debugging and profiling experience (preserving stack traces), good minification by advanced javascript optimizing compilers.
