tiptap is a renderless and extendable rich-text editor (WYSIWYG) for Vue.js that is built on top of Prosemirror. What stands out is the many different options it includes such as a full toolbar, an inline editor, suggestions, markdown mode, and more.

What comes out of the editor when you save is also made for developers because you can get a raw HTML string or a JSON-serializable representation of your document.
