Working with the ckeditor4 repostiory

Attention: The code in this repository should be used locally and for development purposes only. We do not recommend using it in a production environment because the user experience will be very limited.

Code installation

There is no special installation procedure to install the development code. Simply clone it to any local directory and you are set.

Available branches

This repository contains the following branches:

  • master – Development of the upcoming minor release.
  • major – Development of the upcoming major release.
  • stable – Latest stable release tag point (non-beta).
  • latest – Latest release tag point (including betas).
  • release/A.B.x (e.g. 4.0.x, 4.1.x) – Release freeze, tests and tagging. Hotfixing.

Note that both master and major are under heavy development. Their code did not pass the release testing phase, though, so it may be unstable.

Additionally, all releases have their respective tags in the following form: 4.4.0, 4.4.1, etc.


The samples/ folder contains some examples that can be used to test your installation. Visit CKEditor 4 Examples for plenty of samples showcasing numerous editor features, with source code readily available to view, copy and use in your own solution.

Code structure

The development code contains the following main elements:

  • Main coding folders:
    • core/ – The core API of CKEditor 4. Alone, it does nothing, but it provides the entire JavaScript API that makes the magic happen.
    • plugins/ – Contains most of the plugins maintained by the CKEditor 4 core team.
    • skin/ – Contains the official default skin of CKEditor 4.
    • dev/ – Contains some developer tools.
    • tests/ – Contains the CKEditor 4 tests suite.

Building a release

A release-optimized version of the development code can be easily created locally. The dev/builder/ script can be used for that purpose:

> ./dev/builder/

A "release-ready" working copy of your development code will be built in the new dev/builder/release/ folder. An Internet connection is necessary to run the builder, for the first time at least.

Testing environment

Read more on how to set up the environment and execute tests in the CKEditor 4 Testing Environment guide.
