CKEditor 4 is a widely used browser-based WYSIWYG rich-text HTML editor with a plugin-based architecture and extensive customization options. The open-source version reached end of life in June 2023; this repository now hosts the commercially licensed CKEditor 4 LTS edition with security fixes guaranteed until December 2029.
Use cases
- add a wysiwyg rich text editor to a web form
- embed an html editor in a cms admin panel
- let users format content without writing html
- customize a rich text editor with plugins
- maintain a legacy app still using ckeditor 4
- edit html content in the browser with toolbar controls
When to choose
- you are maintaining an existing application already built on CKEditor 4 and need continued security patches via the LTS program
- you need a mature, plugin-rich WYSIWYG editor compatible with legacy browsers and older stacks
- you can accept the commercial Extended Support license terms through 2029
When to avoid
- you are starting a new project - CKEditor 4 is past end of life and the open-source version receives no security updates
- you want a fully open-source editor without commercial licensing obligations
- you need modern features like real-time collaboration or AI assistance, which are CKEditor 5 offerings
