BlockNote vs. Editor.js vs. HTML vs. Slate Comparison Chart

​BlockNote is an open source, block-based rich text editor for React that offers a polished, Notion-style user experience with minimal setup. It comes with built-in UI components like menus and toolbars, which are fully customizable. It supports drag-and-drop functionality, allowing users to organize content into blocks that can be nested or rearranged. Developers can extend the editor with custom blocks, schemas, and plugins, benefiting from first-class TypeScript support for type safety and autocompletion. BlockNote enables real-time collaboration using Yjs, with support for providers like Liveblocks and PartyKit, allowing multiple users to edit documents simultaneously. It also supports theming, markdown, and HTML conversion, and can be used with vanilla JavaScript for non-React projects. Built on top of ProseMirror and TipTap, BlockNote simplifies the process of adding a rich text editor to applications, eliminating the need to build interface elements from scratch.

HTML, short for HyperText Markup Language, is the markup language that is used by every website on the internet. HTML is code that websites use to build and structure every part of their website and web pages. HTML5 is a markup language used for structuring and presenting content on the World Wide Web. It is the fifth and final major HTML version that is a World Wide Web Consortium (W3C) recommendation. The current specification is known as the HTML Living Standard. It is maintained by the Web Hypertext Application Technology Working Group (WHATWG), a consortium of the major browser vendors (Apple, Google, Mozilla, and Microsoft). HTML5 includes detailed processing models to encourage more interoperable implementations; it extends, improves, and rationalizes the markup available for documents and introduces markup and application programming interfaces (APIs) for complex web applications. For the same reasons, HTML5 is also a candidate for cross-platform mobile applications.
