Telerik is having a vast range of the products for the UI and front-end development which is also compatible with Bootstrap,
Telerik does have multiple products like KendoUI for the website and other UI design components for the Mobile and Desktop to use the minimalistic and clean design from their theme library and can also provide the various components which help reduce to developer’s time in UI and Front-End Designing and increase the productivity too. Also, Telerik provides multiple types of chart, reports etc to display in web/desktop/mobile applications. The biggest advantage is to use the Telerik KendoUI or Controls that it's come up with responsive for the web so the developer does not have to write the code specifically to make it responsive using the HTML5 or Bootstrap.
