Is there an open source analogue of such editors as Tilda, ReadyMag, etc.?

Question

JavaScript

You need an editor like Tilda, ReadyMag. The bottom line is that there are pre-designed and created blocks: title, text from one to six columns. Parallax backgrounds and videos. Thanks to this, you can create a web magazine in 20-30 minutes.
However, their prices are expensive, and many features are not needed. Are there open source equivalents of such wysiwyg editors?

Answer 1

CKeditor + plugin API + custom CSS connection + competent workbench
In the editor, unfortunately, not everything will be the same as on the screen, but if you set a goal to do it right, then everything will look like the truth.
On the other hand, the issue of free of charge should only be of concern if there is no money at all and there are hands or competent free associates. In any other case, the layout of such a longread will cost much more than 1500 rubles ($25 per month). We ourselves in the editorial office use both options - for everyday life - finished CKeditor, for exclusives - a subscription to Tilda.
