CKEditor 5 vs Quill

CKEditor 5 is a TypeScript and JavaScript framework for building WYSIWYG rich-text editing experiences. Its editing tools cover text formatting, images, media embeds, links, tables, and lists, with HTML or Markdown output. Collaboration features include comments, change tracking, restricted editing, and revision history. It can export content to PDF or Word and import DOCX documents. Official integrations are documented for Angular, React, Next.js, Nuxt, Vue, Salesforce, Svelte, Spring Boot, jQuery, SharePoint SPFx, and Drupal. Setup options include npm, CDN, and ZIP. The self-hosted editor can be used without an account under the GPL, subject to compliance, and displays a Powered by CKEditor logo; commercial self-hosting requires a custom plan and sales contact. A free plan includes 1,000 monthly editor loads, then $60 per extra 1,000. Paid plans start at $144 per month billed annually, and a 14-day premium-features trial requires no credit card. Cloud plans count monthly loads, charge for additional blocks of 1,000, and do not roll unused loads over.

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.
