SuperDoc

A JavaScript library that renders and edits DOCX files in the browser, headless on the server, and within agentic workflows.
Tracked changes, complex tables, headers/footers, real-time collaboration — the features your users actually need.
Self-hosted. Open source. Works with React, Vue, and vanilla JS.

Quick start

npm install superdoc

React

npm install @superdoc-dev/react

import { SuperDocEditor } from '@superdoc-dev/react';
import '@superdoc-dev/react/style.css';

function App() {
  return (
    <SuperDocEditor
      document={file}
      documentMode="editing"
      onReady={() => console.log('Ready!')}
    />
  );
}

See the @superdoc-dev/react README for full React documentation.

Vanilla JavaScript

import 'superdoc/style.css';
import { SuperDoc } from 'superdoc';

const superdoc = new SuperDoc({
  selector: '#superdoc',
  toolbar: '#superdoc-toolbar',
  document: '/sample.docx',
  documentMode: 'editing',
});

Or use the CDN:

<link rel="stylesheet" href="https://unpkg.com/superdoc/dist/style.css" />
<script type="module" src="https://unpkg.com/superdoc/dist/superdoc.umd.js"></script>

For all available options and events, see the documentation or SuperDoc.js.

Features

• Real DOCX, not rich text — Built on OOXML. Real pagination, section breaks, headers/footers. Not a contenteditable wrapper with export bolted on.
• Self-hosted — Runs entirely in the browser. Your documents never leave your servers.
• Any framework — React, Vue, Angular, Svelte, vanilla JS. One component, zero lock-in.
• Real-time collaboration — Yjs-based CRDT. Multiplayer editing with comments, tracked changes, and automatic conflict resolution.
• Agentic tooling — Runs headless in Node.js. Bring your own LLM for document automation, redlining, and template workflows.
• Extensible — 60+ built-in extensions. Write custom plugins with full ProseMirror access.
• Dual licensed — AGPLv3 for community use. Commercial license for proprietary deployments.
