SuperDoc renders and edits DOCX files in the browser. Built on OOXML — not bolted onto HTML. As you type, you write directly to the XML. Import a document, edit it, export it. Nothing lost.

## Features

- **Real DOCX, not rich text** — Built on OOXML. Real pagination, section breaks, headers/footers, complex tables. 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.
- **Built for agents** — [SDK](https://www.npmjs.com/package/@superdoc-dev/sdk), [CLI](https://www.npmjs.com/package/@superdoc-dev/cli), and [MCP server](https://www.npmjs.com/package/@superdoc-dev/mcp) let LLMs read, edit, and save .docx files programmatically.
- **Dual licensed** — AGPLv3 for community use. [Commercial license](https://www.superdocportal.dev/get-in-touch) for proprietary deployments.

## Quick start

```bash
npm install superdoc
```

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

const superdoc = new SuperDoc({
  selector: '#superdoc',
  documents: [
    {
      id: 'my-doc-id',
      type: 'docx',
      data: fileObject,
    },
  ],
});
```

For React, Vue, and other frameworks, see the [documentation](https://docs.superdoc.dev).

### Using an AI coding agent?

```bash
npx @superdoc-dev/create              # generates AGENTS.md for your framework
claude mcp add superdoc -- npx @superdoc-dev/mcp   # connect agent to DOCX files
```
