Best Free WYSIWYG HTML Editor for WordPress in 2026 (v2.0.10)

WordPress Editor Landscape in 2026

WordPress ships with Gutenberg as its default editor. Gutenberg is powerful for block-based layouts but is not a general-purpose WYSIWYG editor library — it cannot be easily embedded in a React component or used outside WordPress. For custom post types, meta boxes, ACF fields, and headless WordPress projects, you need a separate WYSIWYG editor.

Use Cases for a Custom WYSIWYG Editor in WordPress

• ACF (Advanced Custom Fields) — rich text fields in custom admin panels
• Meta boxes — custom editor fields below the main post editor
• Page builder integrations — inline editing in custom blocks
• Headless WordPress — React/Vue frontend consuming WP REST API or WPGraphQL
• WordPress plugin UIs — settings pages with rich text fields

WordPress WYSIWYG Editor Comparison

RayEditor in a WordPress Admin Meta Box

// In your plugin's PHP file, enqueue assets:
function my_plugin_enqueue() {
    wp_enqueue_style('ray-editor', 'https://cdn.jsdelivr.net/npm/@rohanyeole/[email protected]/dist/ray-editor.css');
    wp_enqueue_script('ray-editor', 'https://cdn.jsdelivr.net/npm/@rohanyeole/[email protected]/dist/ray-editor.umd.js', [], null, true);
    wp_enqueue_script('my-editor-init', plugin_dir_url(__FILE__).'editor-init.js', ['ray-editor'], null, true);
}
add_action('admin_enqueue_scripts', 'my_plugin_enqueue');

// editor-init.js
document.addEventListener('DOMContentLoaded', function() {
  const el = document.getElementById('my-rich-field');
  if (!el) return;
  const editor = new window.RayEditor(el, {
    placeholder: 'Enter content...',
    toolbar: ['bold','italic','link','orderedList','unorderedList']
  });
  // Save HTML to hidden input on form submit
  document.querySelector('form').addEventListener('submit', () => {
    document.getElementById('my-rich-field-value').value = editor.getContent();
  });
});

RayEditor in a Headless WordPress + React Frontend

// Fetch content from WP REST API and edit with RayEditor
import { RayEditor } from '@rohanyeole/ray-editor-react';

function PostEditor({ postId }) {
  const [content, setContent] = React.useState('');

  React.useEffect(() => {
    fetch(`/wp-json/wp/v2/posts/${postId}`)
      .then(r => r.json())
      .then(p => setContent(p.content.rendered));
  }, [postId]);

  return <RayEditor value={content} onChange={setContent} />;
}

Conclusion

For headless WordPress projects with React, Vue, or Angular frontends, RayEditor is the best free WYSIWYG editor choice in 2026. MIT licensed, clean HTML output, and official framework wrappers make it a natural fit. For traditional WordPress admin custom fields, RayEditor's CDN UMD build works without a build step.
