The only Kendo UI product which is offered with GPLv3 licensing is Kendo UI Web, available here
. This license is permissive if you develop GPL-compatible projects, and Kendo UI Web can be used as a client library in ASP.NET MVC solutions.
If you would like, however, to utilize Kendo UI Complete for ASP.NET MVC (which includes MVC server wrappers for Kendo UI Web and DataViz), you can evaluate the product for 30 days and then decide whether to buy a commercial license. More information about this product and its licensing model can be gathered from this public FAQ
