Kendo UI is a HTML5 for web and mobile app development on JavaScript framework. It has extra features for Paid version. But the version that is available for free with GNU GPL 3.0, is enough for the developers for creating nice webpages for the apps to show demo.
We basically uploaded Kendo UI for our tutorial for Creating and Uploading a GitHub Project From GUI.
As there is no meaning of deleting the repo, we kept it. You can fork with GNU GPL 3.0 License.
