Quill vs RichTextEditor

Quill is a free, API-driven rich text editor for developers. Its API exposes content, changes and events using JSON, with operations that access or modify content by indexes and lengths. The document model supports extensions for custom formats and embeds, including slide decks, interactive checklists and 3D models. Built-in formatting covers text styles, links, headings, lists, alignment, code blocks, images and video; formulas require KaTeX. Official modules provide configurable toolbar, clipboard, keyboard, history and syntax features. History supports undo and redo with adjustable delay, stack size and handling of programmatic changes. Clipboard matchers control copy, cut and paste, and the documentation warns that unsafe HTML handling can create cross-site scripting vulnerabilities. Developers can configure toolbar handlers or provide custom HTML. Quill includes Snow and Bubble themes, runs in modern desktop, tablet and phone browsers, and can be loaded from jsDelivr or npm with full and core builds. Slab maintains it under a BSD license for personal and commercial projects.
