    Ludwika,

    I'm wondering if you could expand on your previous comments regarding the use of CKEditor in a commerical website.  I'm not sure I understand what it means when you say your source code must remain open and accessible to others.  My website runs on my server and uses CKEditor. I am not making any changes to the CKEditor code. I am using it as-is.  The code that constitutes the website is not distributed in the normal sense of distributing an application.  Do I need to provide a link somewhere on the website to the CKEditor code?  I just don't understand what it means for the code to be accessible in the context of a website.

    Thank you for any clarification you can provide on this matter.

    Hi Ludwika,

    I also have exactly same question as Marty, Can you explain which source code we have to make public? CKEditor code or my website source code?

     

    Thanks.

    Hi Ludwika,

    i also have the same question as Marty and Whop.

    When using your official ckeditor 5 wrapper for angular:

    • is the editor free to use or do we have to pay for it?
    • how would we make the source code for ckeditor 5 accessible for the enduser?
    • is there anything else we need to be aware of?

    Thanks.

    Unfortunately I believe I accidentally deleted the response that Ludwika  sent me several months ago.  Could you re-response to my original question, please.  

    Thank you.

    Hi Muhammad,

    Thank you for your comment. As long as you are complaint with legal restrictions of an Open Source license of your choice and do not require any customer care services from us, you are welcomed to use CKEditor as an Open Source software.

    I would like to use the open source CKEditor in my closed-source commercial product as a way for users to define email content.  Obviously I don't want to open-source my source code.  Is this allowed under the terms of the open source license?  (I understand there is no support under the terms of the open source license)

    Hi Rik,

    Thank you for the question. Yes, we do not provide support to users owith Open Source license. To make a legally valid decision, you would need to review Open Source licenses available for CKEditor with your legal team. We do not provide such advice as we are not experts in this domain.

    Hi.
    If my project includes ckeditor 5, and use existing API to customize it,e.g. add new toolbar item, do I need to open source my whole project source?

    Hi Mingoal,

    Thank you for your comment. In order to use CKEditor 5 as an Open Source software, you need to be compliant with GPL2+ license, regardless of your use case.
