Quill

Quill is an open-source, customizable rich text editor designed for web developers. It provides a modular architecture and an expressive API, allowing for extensive customization and integration into various web applications. It focuses on providing a robust editing experience rather than a full publishing platform.

Quill is explicitly described as a "powerful rich text editor" and a "free, open source WYSIWYG editor built for the modern web." Its documentation and examples heavily feature text formatting, image embedding, and custom styling capabilities, directly aligning with the 'rich-text-editor' feature. However, it is a component for developers to build with, not a complete publishing platform with distribution, monetization, or community features.
