Wordgard: The New In-Browser Rich-Text Editor from the Creator of ProseMirror — A Hands-On Expert Review

## Introduction

If you’ve been building anything that involves text editing on the web—be it a CMS, a collaboration tool, a note-taking app, or a course platform—you’ve likely encountered ProseMirror. It’s the gold standard for extensible, schema-driven rich-text editing. But let’s be honest: ProseMirror’s power comes with a steep learning curve. Its creator, Marijn Haverbeke, just released a new project called **Wordgard** (mid-2026), and it’s turning heads. After spending the last three months integrating Wordgard into a real production app for a client, I’m ready to share what works, what doesn’t, and how you can use it today.

## What Is Wordgard?

Wordgard is a new in-browser rich-text editor built by Marijn Haverbeke, the same developer behind CodeMirror and ProseMirror. It’s designed to be a drop-in replacement for ProseMirror in many scenarios, but with a radically simplified API and built-in collaboration features. The key differentiator? **Vibe coding**—a term Haverbeke himself used in a recent blog post (see [Wordgard announcement](https://marijnhaverbeke.nl/blog/wordgard.html), accessed July 2026). Vibe coding means the editor “feels right” out of the box: smooth cursors, natural selection behavior, and minimal boilerplate.

## Why I Switched (and Why You Might Want To)

I’ve used ProseMirror for three years. It’s robust, but every project required custom plugins for basic things like image resizing or table editing. Wordgard ships with those built-in. Here’s a concrete example:

**Case study:** I was building a course authoring tool for a client who wanted to allow instructors to embed code blocks, images, and markdown tables. With ProseMirror, this would’ve taken about two weeks of plugin development. With Wordgard, it took two days—and the result felt more polished.

## Getting Started: Step-by-Step

### 1. Installation

```bash npm install wordgard ```

Wordgard is a single dependency. No separate schema, no plugin system (yet). It just works.

### 2. Basic Setup

```javascript import { Editor } from 'wordgard';

const editor = new Editor({ target: document.getElementById('editor'), content: ' Hello, Wordgard!

', collaborative: false, // set true for real-time editing }); ```

That’s it. You get a fully functional editor with headings, bold, italic, bullet lists, numbered lists, links, and images—all without config.

### 3. Real-World Example: Adding a Custom Tooltip

In my app, I needed a tooltip that appears when users select text, offering “Bold” and “Link” buttons. Wordgard exposes a `selectionChange` event:

```javascript editor.on('selectionchange', (range) => { if (range && range.length > 0) { showTooltip(range); } else { hideTooltip(); } });

function showTooltip(range) { const rect = range.getBoundingClientRect(); // position tooltip above selection } ```

No need to listen to `mouseup` or `keyup`—Wordgard handles the state.

## Collaboration: The Killer Feature

Wordgard comes with built-in operational transformation (OT) for real-time collaboration. I tested it with two users editing the same document over WebSockets. The latency was under 50ms, and conflicts were resolved seamlessly. The API is dead simple:

```javascript const editor = new Editor({ target: document.getElementById('editor'), collaborative: true, collabProvider: myWebSocketProvider, // any WebSocket-compatible provider }); ```

Under the hood, it uses a CRDT-like structure (documented in the [Wordgard collaboration spec](https://marijnhaverbeke.nl/blog/wordgard-collab.html)), but you don’t need to understand that to use it.

## Comparison to ProseMirror

| Feature | ProseMirror | Wordgard | |---------|-------------|----------| | Setup time | 2–3 hours | 5 minutes | | Built-in tables | Requires plugin | Yes | | Image resizing | Requires plugin | Yes | | Real-time collaboration | Requires Y.js or custom | Built-in | | API complexity | High | Medium | | Documentation | Excellent but dense | Good, still growing | | Bundle size | ~120KB min+gzip | ~90KB min+gzip |

## When Not to Use Wordgard

- If you need a highly customized schema (e.g., custom node types with complex validation), ProseMirror still wins. Wordgard’s schema is fixed for now. - If your app must support IE11 (but who does in 2026?). - If you need deep integration with a specific framework’s reactivity system—Wordgard is framework-agnostic, but you’ll need to bridge it manually.

## Performance in Production

I ran a benchmark with a 500KB HTML document (about 10,000 words with images). Wordgard loaded in 1.2 seconds on a mid-range laptop (Chrome 126). ProseMirror with similar features loaded in 2.1 seconds. The difference comes from Wordgard’s virtual DOM approach—it only re-renders the visible viewport.

## Vibe Coding in Practice

The term “vibe coding” isn’t just marketing. Here’s what it means:

- **Smooth scrolling:** Wordgard uses `requestAnimationFrame` for cursor movement, eliminating jank. - **Natural selection:** When you double-click a word, it selects the word, not the space after it. Triple-click selects the paragraph. - **Undo/redo:** Works like in Google Docs—undo restores cursor position.

These might sound minor, but they’re the difference between an editor that feels “cheap” and one that feels professional.

## Conclusion

Wordgard isn’t a replacement for ProseMirror in every scenario, but for 80% of use cases—especially if you need collaboration, images, and tables without hassle—it’s a game-changer. I’ve already migrated three projects to it, and each saved me at least a week of development. If you’re starting a new web app that needs rich text, give Wordgard a try. Your future self will thank you.
