CKEditor Open Source licenses

CKEditor is distributed under the GPL, LGPL and MPL Open Source licenses. This triple copyleft licensing model is flexible and allows you to choose the license that is best suited for your needs.

• GPL Free Software

  About license

  The GPL grants the recipients of a computer program the rights of the free software definition and uses copyleft to ensure the freedoms are preserved, even when the work is changed or added to.

• LGPL Free Software

  About license

  The LGPL places copyleft restrictions on the program governed under it but does not apply these restrictions to other software that merely link with the program. The main difference between the GPL and the LGPL is that the latter allows the work to be linked with a non-(L)GPLed program, regardless of whether it is free software or proprietary software.

• MPL Mozilla Foundation

  About license

  The MPL allows covered source code to be mixed with other files under a different, even proprietary license. However, code files licensed under the MPL must remain under the MPL and be freely available in source form.
