Kendo UI is a comprehensive framework for building modern web and mobile applications with HTML5, JavaScript and CSS. It offers a wide range of UI widgets, such as data grids, charts and gauges, as well as several ready-to-use themes. The framework is designed to help developers quickly and easily create powerful, responsive and interactive applications with minimal effort. The library also includes a range of tools to help speed up development, such as a drag-and-drop designer, and a rich set of APIs for manipulating UI elements. Kendo UI is available for both free and commercial use.
It is a complete web UI framework. It has many more widgets than Bootstrap and almost as many as Kendo UI. It is easy to use, feels lightweight and has a nice default theme.
No data grid - this is a big difference
