Compatibility and Requirements

Kendo UI Core depends on the following libraries:

Kendo UI Core has not been tested against any other versions of these libraries. You may find that versions other than these are compatible with Kendo UI Core. However, we make no claims to support those versions, and will not troubleshoot issues that arise when using those versions.

Building Kendo UI Core

There are two ways to get the source code for Kendo UI Core. You can either download a pre-built zip from, or build the source yourself using Grunt. The latter approach includes an option for building a distribution of Kendo UI Core that includes only the widgets and framework features required by your app.

Installing Dependencies

In order to build Kendo UI Core, you need to have Node.js/npm latest and git 1.7 or later.

For Windows you have to download and install git and Node.js.

Mac OS users should install Homebrew. Once Homebrew is installed, run brew install git to install git, and brew install node to install Node.js.

Linux/BSD users should use their appropriate package managers to install git and Node.js, or build them from source.

How to build Kendo UI Core

Clone a copy of the repository by running

git clone

Enter the repository directory

cd kendo-ui-core

Initialize the submodule repository

git submodule update --init

Run the build script:

npm run build

The minified version of the scripts and styles of Kendo UI Core will be put in the dist/ subdirectory.

If you want to create custom build or help with Kendo UI Core development, it would be better to install the grunt command line interface as a global package:

[sudo] npm install -g grunt-cli

Make sure you have grunt installed by testing:

grunt --version

Now by running the grunt command in the Kendo UI Core directory, you can build the full version of Kendo UI Core. This works just like the npm run build command:

grunt build

There are several other tasks available:

grunt --help

Building only what you need

The grunt custom task will create a custom minified file - dist/kendo.custom.min.js, which includes only the specified components. The following command will include only the autocomplete and dropdownlist widgets:

grunt custom:autocomplete,dropdownlist

Source Code and Downloads

If you want to skip building Kendo UI Core yourself, head on over to to grab the full source.

Using Kendo UI Core via the Kendo Static CDN

You can also easily include Kendo UI Core in your site or application by using the Kendo CDN:

<link href="" rel="stylesheet" />
<link href="" rel="stylesheet" />
<script src=""></script>
<script src=""></script>

The main advantage of the CDN approach is that your users may be able to leverage a primed cache version of Kendo UI Core if they've visited other sites using the framework.
