What Is CKEditor?
CKEditor is a WYSIWYG (What You See Is What You Get) editor built with JavaScript and TypeScript that transforms how you create and manage content. At its core, CKEditor offers a plugin-based architecture that makes it incredibly flexible and adaptable to specific content needs, whether you're crafting short social media posts or comprehensive documentation.
What distinguishes CKEditor from other rich text editors is its comprehensive, customizable nature. It produces clean HTML output without the messy markup that often affects other editors. CKEditor provides professional-grade content tools that create clean, semantic HTML without bloat.
The interface can be tailored to match exact workflow requirements. You can add features, remove unnecessary ones, customize toolbars, and integrate specialized plugins based on content requirements. Media management becomes straightforward, too—simply embed images, videos, and other rich media directly within your content.
Why Integrate CKEditor with Strapi
Integrating CKEditor with Strapi helps you solve a classic headless CMS challenge: you get powerful backend flexibility while also providing a user-friendly, sophisticated rich text editing experience. This integration enhances content creation while maintaining Strapi's API-first architecture, benefiting both development teams and content creators.
For developers, the advantages are clear. Content gets stored as clean HTML that's ready for consumption via REST or GraphQL endpoints without any data transformation. The plugin-based setup enables quick integration, allowing you to focus on customization rather than building an editing infrastructure from scratch. The architecture adapts to specific project needs, while customization options let you tailor the editor interface to match exact requirements.
Content managers benefit as well. They get rich text formatting, media embedding, and intuitive WYSIWYG functionality. The interface displays content exactly as it will appear to end users, eliminating guesswork and reducing revision cycles. Different presets accommodate various content types—from quick social posts to in-depth articles. Features like max length validation provide visual feedback similar to social platforms, while fullscreen expansion allows editors to focus entirely on content creation.
Strapi Cloud and v5 make integration even smoother with additional features and better compatibility. These updates enhance performance and support modern development workflows, especially for distributing content across multiple platforms and devices, enabling multi-platform publishing.
By pairing a WYSIWYG editor with a headless CMS like Strapi, content creators remain productive, especially when choosing one that's adaptable, continuously improved, and future-ready, like CKEditor. The result? A content management solution that satisfies both technical requirements and user experience needs.

How to Integrate CKEditor with Strapi
Integrate CKEditor with Strapi to provide your content team with a powerful WYSIWYG interface inside your headless CMS. Here's how to implement it properly, from plugin selection to testing.
Prerequisites and Compatibility
Strapi Version Requirements
Version matching is critical for stability. Strapi 5.0.0 and above require CKEditor plugin version 1.x.x. Strapi versions 4.4 to below 5.0.0 need legacy CKEditor plugin versions.
The custom fields feature introduced in Strapi 4.4 is required, as CKEditor functions as a custom field within your content types.
Node.js and Package Manager Requirements
Node.js with NPM or Yarn must be installed, as both Strapi and its plugins install through these package managers.
Plugin Options Available
Two main options exist: the official CKEditor 5 Integration is a premium option requiring a valid license key, while the Community Edition provides extensive functionality at no cost.
Strapi Version | CKEditor Plugin Version | Notes |
---|---|---|
5.0.0+ | 1.x.x (Official or Community) | Full feature support |
4.4 - 4.x | Legacy versions | Custom fields required |
Below 4.4 | Not supported | Missing custom fields |
Check for the latest compatibility information as versions evolve. Mismatched plugin versions cause integration conflicts that disrupt development. Staying informed about web development trends in 2025 ensures that your technology stack remains current and compatible with the latest tools.
Choosing Between Official and Community Plugins
Before installation, you will need to select between the two options. The official CKEditor 5 Integration is premium and requires a valid license key. It offers comprehensive support, regular updates, and premium features directly from the team.
The Community Edition is free and community-maintained, with an impressive set of features: media library integration, dark theme support, and responsive image handling included.
Choose the official version if you need premium features, dedicated support, and official maintenance. Select the community option if you're budget-conscious or if the available features meet your requirements.
When deciding between versions, consider the differences in support and funding that come with different open-source business models.
Installing the Official CKEditor 5 Plugin
The official plugin requires several configuration steps beyond basic installation. Start by adding the package:
1npm install @ckeditor/strapi-plugin-ckeditor
Or with Yarn:
1yarn add @ckeditor/strapi-plugin-ckeditor
You will need a Content Security Policy configuration to load resources from external sources. Modify your config/middlewares.ts
file:
1export default [
2 {
3 name: 'strapi::security',
4 config: {
5 contentSecurityPolicy: {
6 useDefaults: true,
7 directives: {
8 'script-src': ['https://cdn.ckeditor.com'],
9 'connect-src': ['https://proxy-event.ckeditor.com']
10 },
11 },
12 },
13 },
14]
Build your application to register the plugin:
1npm run build && npm run develop
Installing the Community Edition Plugin
The community edition installation varies slightly by version. For Strapi v5:
1yarn add @_sh/strapi-plugin-ckeditor
Follow the standard build:
1yarn build && yarn develop
For Strapi v4 users, version 3 of the community plugin remains available until March 2026, receiving only essential bug fixes. The v4 installation process differs from v5, so check the specific documentation.
The community edition comes ready with two presets: a Default HTML editor outputting formatted HTML and a Default Markdown editor for Markdown output. Both include comprehensive plugin sets.
Configuring CKEditor in Strapi
Once installed and built, the editor becomes available as a custom field in your Content-Type Builder. You will find it in the "CUSTOM" tab when adding new fields.
The configuration interface allows you to select between presets and customize the editor for specific content types. Combined with Strapi's role-based access control, you can tailor each field for different scenarios—short notes, blog articles, or comprehensive documentation—while controlling who has access to which content.
In addition to configuring CKEditor, exploring AI tools for content management can further enhance your content creation process. Key features include max length validation with visual indicators, responsive image support, and dark theme compatibility. Media library integration allows editors to insert images and videos directly from your existing asset collection using the Strapi Media Library.
Testing the Integration
After installation and configuration, thorough testing ensures everything works correctly. Create a test content type with a field and verify that the editor loads properly. Test core functionality by creating sample content with rich formatting, embedded media, and various text styles. Ensure that content saves correctly and displays as expected through API endpoints.
Watch for Content Security Policy errors with the official plugin, missing dependencies that prevent loading, and plugin conflicts. If issues arise, verify that all build steps have been completed and that environment variables are configured correctly.
Performance testing is also important—check that the editor loads quickly and responds smoothly, especially with large content amounts or multiple media assets. Monitor server logs during testing to identify any integration-specific errors.
Stay connected with both communities by monitoring the GitHub repositories for bug reports and feature requests. The Strapi Community Forum and CKEditor support channels provide solutions to common problems. Check the official Strapi integrations page regularly for plugin updates and compatibility information.

This example focuses on a streamlined blog platform with customized editing experiences for different user roles. The implementation includes:
1// config/plugins.js
2module.exports = {
3 ckeditor: {
4 enabled: true,
5 config: {
6 editor: {
7 // Editor configuration
8 toolbar: {
9 items: [
10 'heading',
11 '|',
12 'bold',
13 'italic',
14 'link',
15 'bulletedList',
16 'numberedList',
17 '|',
18 'imageInsert',
19 'blockQuote',
20 'insertTable',
21 'mediaEmbed',
22 'undo',
23 'redo',
24 ]
25 }
26 }
27 }
28 }
29};
The project demonstrates role-based toolbar configurations, where administrators get full editing capabilities while content creators receive a simplified interface:
1// api/article/models/article.json
2{
3 "attributes": {
4 "title": {
5 "type": "string",
6 "required": true
7 },
8 "content": {
9 "type": "customField",
10 "customField": "plugin::ckeditor.CKEditor",
11 "options": {
12 "preset": "standard",
13 "maxLength": 5000
14 }
15 }
16 }
17}
On the frontend, we implement efficient content rendering with appropriate sanitization:
1import React from 'react';
2import DOMPurify from 'dompurify';
3
4const ArticleContent = ({ content }) => {
5 const sanitizedContent = DOMPurify.sanitize(content);
6
7 return (
8 <div
9 className="article-content"
10 dangerouslySetInnerHTML={{ __html: sanitizedContent }}
11 />
12 );
13};
14
15export default ArticleContent;
This project showcases best practices for media handling, with Strapi's media library fully integrated into the CKEditor instance, allowing content creators to seamlessly insert and manage images while maintaining proper attribution and responsive behavior across devices.
For developers looking to implement similar solutions, this example provides clear patterns for configuration, security, and frontend integration that can be adapted to various content management needs.
