r/reactjs on Reddit: seeking a fully open-source, free, wysiwyg editor that is easy to customize and extend
May 30, 2025 -

Here is the text edtior I have for now, snap: https://imgur.com/ANWN16v

I want to keep these cools wysiwyg editors like tinymce or ckeditor. But the thing is they are for API, not fully open source. Really hard to write plugin or modify.

Do you guys have any suggestion? Other than these, fully open source.

I have tried editorjs but that's block editor. I am looking for something out of the box solution, so that I can add my plugin or extension easily.
