CKEditor comes under two ways of licensing: Open Source and commercial.
For the Open Source licensing:
- CKEditor 5 is distributed under a GPL 2+ copyleft Open Source license (if you are running a project with an OSS license incompatible with GPL, please contact us and we will be happy to support it with a free CKEditor 5 license).
- CKEditor 4 is distributed under three copyleft Open Source license options: GPL, LGPL, MPL.
If you are working on a SaaS project, creating a commercial application, or just need more flexibility, you can purchase a commercial license that allows special license terms, white-labelling, and dedicated support. Visit the pricing page for details.
Please note that CKEditor 4 reached its End of Life (EOL) in June 2023. From then on, it receives no more updates, new features, bug fixes, and most importantly, security patches.
If you have an active CKEditor 4 subscription and need help, you can contact our support team. If you are not ready to migrate yet, for a limited time we are offering a paid Extended Support Model that will protect you against security vulnerabilities and/or breaking third-party API changes.
