MDXEditor vs Quill

MDXEditor is a web-based React component for writing Markdown in a rich-text editor. It accepts and returns Markdown strings, without converting documents through an intermediate HTML representation. Its editing engine uses Lexical, and developers can add capabilities with plugins or build plugins for additional Markdown constructs. Listed tools include headings, quotes, links, lists, images, tables, code blocks, front matter, shortcuts, directives, JSX components, source editing, diff views, and a customizable toolbar. Table editing covers rows, columns, and alignment, with Markdown allowed in cells but not HTML tables. Images can come from URLs or local devices, be pasted or dropped, and use an integrator-provided upload handler. Code blocks support syntax highlighting and language-aware editing, with CodeMirror available for editable blocks. It is installed from npm in React projects and has setup guides for Next.js, Vite, Remix, and Create React App. It is self-hosted, free at free, and licensed under MIT. Server rendering and changes to font size, color, or family are not supported.

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.
