For many companies and products Open Source licenses are not an option. This is why the
CKSource Closed Distribution License (CDL) has been introduced. It is a
non-copyleft license which gives companies complete freedom when integrating CKEditor into their products and websites.
This license offers a very flexible way to integrate CKEditor into your commercial application. The commercial license has the following advantages over the Open Source one:
- Professional assistance from CKEditor development team is available to you via a dedicated support channel.
- Modifications and enhancements to the editor do not need to be released under an Open Source license.
- There is no need to distribute any Open Source license terms alongside with your product and no references to them have to be done.
- No references to CKEditor have to be done in any files distributed with your product.
- The source code of CKEditor does not have to be distributed alongside with your product.
- You can remove any file from CKEditor when integrating it with your product.
- Your financial contribution helps us improve the editor even further, add new features, and maintain the high quality that made you choose CKEditor in the first place!
The CDL is a lifetime license valid for all releases of CKEditor published during and before the year following your purchase. It is valid for FCKeditor releases, too. The CDL includes
one year of dedicated e-mail support from the original CKEditor development team.
