Rich Text Editors

This is one of the deepest categories in the JS ecosystem. The right choice depends on whether you're building a Notion-style block editor, a Google-Docs-style document, a comment box, or a markdown editor.

ProseMirror-based (most popular foundation)

• ★ Tiptap — by far the most popular ProseMirror wrapper. Headless, extensible, large ecosystem of extensions (tables, mentions, collab, AI). Free for the editor; some Pro extensions are paid; collab via Hocuspocus is free self-host.
• ProseMirror — the underlying library. Use directly if you want maximum control.
• Remirror — older Tiptap competitor, less active.

Lexical-based

• ★ Lexical — Meta's editor (powers Facebook comments). React-first, plugin-based, fast. Good fit for "comments" or "rich text fields" use cases.
• Plate — React + Tailwind block editor on top of Slate/Lexical (Plate v40+ supports Lexical and Slate). shadcn-style copy-paste components.

Block editors (Notion-style)

• ★ BlockNote — Notion-style, opinionated, built on Tiptap. The fastest path to a Notion-feeling editor.
• ★ Plate — block editor toolkit; very flexible, you assemble it.
• Editor.js — block editor; older but mature.
• Outstatic / GitBook OSS / AppFlowy editor — bundled into other products.

Slate-based

• Slate — react-only, very flexible, lower-level than Tiptap. Plate sits on top.

Markdown / code editors

• ★ Monaco Editor — the editor from VS Code. Best choice for code editing in a browser.
• CodeMirror 6 — modular, fast, pluggable. Underlying tech for many markdown editors.
• Milkdown — markdown editor on ProseMirror; middle ground between Tiptap and a true markdown editor.
• MDXEditor — WYSIWYG MDX editor.
• react-md-editor, Toast UI Editor — lighter markdown editors.

Specialty

• Quill — older WYSIWYG; Quill 2 is a healthy refresh.
• Trix (Basecamp) — minimalist WYSIWYG.

Pick this if…

• Default rich-text in a React app: Tiptap.
• Notion-style blocks fast: BlockNote.
• Comments / messages / Facebook-style rich input: Lexical.
• Code editing: Monaco.
• Markdown editor: CodeMirror 6 (build) or Milkdown (WYSIWYG markdown).
• You want shadcn-style copy-paste components: Plate.
