BlockNote vs. Editor.js vs. Less vs. Swift 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.

Less (which stands for Leaner Style Sheets) is a backwards-compatible language extension for CSS. This is the official documentation for Less, the language and Less.js, the JavaScript tool that converts your Less styles to CSS styles. Because Less looks just like CSS, learning it is a breeze. Less only makes a few convenient additions to the CSS language, which is one of the reasons it can be learned so quickly. Mixins are a way of including ("mixing in") a bunch of properties from one rule-set into another rule-set. Less gives you the ability to use nesting instead of, or in combination with cascading.
