Writers and developers requiring a toolkit for building rich-text editors on the web
About ProseMirror
Rich content editors should, ideally, produce clean, semantically meaningful documents while still being easy for users to understand. ProseMirror tries to bridge the gap between editing explicit, unambiguous content like Markdown or XML, and classical WYSIWYG editors. It does this by implementing a WYSIWYG-style editing interface for documents more constrained and structured than plain HTML. You can customize the shape and structure of the documents your editor creates, and tailor them to your application's needs. ProseMirror has built-in, ground-up, rock solid support for collaborative editing, where multiple people work on the same document in real time. Document schemas allow editing documents with a custom structure without writing your own editor from scratch. A modular architecture makes sure you only load the code you need, and can replace parts of the system as needed. A plugin system allows you to easily enable additional functionality.

BlockNote
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.

Slate
Slate is a completely customizable framework for building rich text editors. Slate lets you build rich, intuitive editors like those in Medium, Dropbox Paper or Google Docs, which are becoming table stakes for applications on the web, without your codebase getting mired in complexity. It can do this because all of its logic is implemented with a series of plugins, so you aren't ever constrained by what is or isn't in "core". You can think of it like a pluggable implementation of contenteditable built on top of React. It was inspired by libraries like Draft.js, Prosemirror and Quill. Slate is currently in beta. Its core API is usable now, but you might need to pull request fixes for advanced use cases. Some of its APIs are not "finalized" and will (breaking) change over time as we find better solutions. The most important part of Slate is that plugins are first-class entities.

Editor.js
Next generation block styled editor. Meet the new editor, on our webpage you can see it in action. It is a block-styled editor, it returns clean data output in JSON, and it is designed to be extendable and pluggable with a simple API. Workspace in classic editors is made of a single contenteditable element, used to create different HTML markups. Editor.js workspace consists of separate Blocks: paragraphs, headings, images, lists, quotes, etc. Each of them is an independent contenteditable element (or more complex structure) provided by Plugin and united by Editor's Core. There are dozens of ready-to-use Blocks and the simple API for creation any Block you need. For example, you can implement Blocks for Tweets, Instagram posts, surveys and polls, CTA-buttons and even games. Classic WYSIWYG-editors produce raw HTML-markup with both content data and content appearance. On the contrary, Editor.js outputs JSON object with data of each Block.
