Editor.js vs Pell

Editor.js is a free, self-hosted block-style editor that structures content and returns it as JSON. Its workspace keeps paragraphs, headings, images, lists, and quotes in separate blocks. Plugins provide the blocks, and developers can create additional ones through the API. The JSON can be rendered for web and mobile clients, Facebook Instant Articles, Google AMP, or audio; it can also be sanitized, validated, and processed on a backend. The getting-started guide includes header, link embed, image, checklist, list, embed, and quote tools. Installation options include npm or Yarn, a CDN, or a local project file. Read-only mode works when every block tool in use supports it. Configuration can localize the editor interface, tool names, tools, and block tunes. Editor.js supports JavaScript and TypeScript, structured content, and table editing, but not real-time collaboration. The site identifies CodeX, a non-profit team, as its maker, and lists the Apache 2 License. Its free plan costs nothing, with no free trial.

Pell is a free, self-hosted WYSIWYG text editor for web pages. It is written in pure JavaScript using ES6 and has no dependencies. The package is listed at 1.38 kB minified and gzipped, or 3.54 kB minified. Built-in actions cover bold, italic, underline, strikethrough, headings, paragraphs, quotes, lists, code, horizontal rules, links, and images. You can add custom actions and decide which controls appear and in what order. Styling can be changed through Pell’s Sass file or by overriding CSS. The onChange callback provides the editor’s HTML output, and the project demonstrates converting that HTML to Markdown with Turndown. Installation is documented through npm or by including a browser script and stylesheet. React and Vue examples are available. Listed browser support includes IE 9+, Chrome 5+, Firefox 4+, Safari 5+, and Opera 11.6+. Pell uses the MIT license.
