Whether you are using the open-source version or a commercial plan, understanding how to obtain and apply your CKEditor 5 license key is crucial for a smooth setup. 📜 Dual-Licensing Model: GPL vs. Commercial CKEditor 5 operates under a dual-licensing model, giving you the flexibility to choose between an open-source and a commercial license based on your project's needs. Your choice determines the type of license key you will use. The Open-Source (GPL) License The open-source distribution is licensed under the terms of the GNU General Public License version 2 or later (GPL 2+). You can use this version in your projects at no cost. Under the GPL, you use the string 'GPL' as your license key in the editor's configuration. Please note that using the GPL version means your project must also be released under a GPL-compatible license. It will also display a small "Powered by CKEditor" logo in the editor area. The Commercial License If the terms of the GPL don't fit your project, or if you need access to premium features and dedicated support, a commercial license is the right choice. It offers several key benefits:
No GPL Restrictions : You are free to integrate CKEditor 5 into proprietary software without being bound by the GPL's copyleft requirements. White-labeling : For all plans except the free one, you can remove the "Powered by CKEditor" logo. Premium Features : Gain access to powerful features like Track Changes, Comments, Revision History, AI Assistant, Real-Time Collaboration, Import/Export from Word and PDF, and more. Technical Support : Receive dedicated technical support, which is not provided for the GPL version. Distribution Options : You can choose between a cloud-hosted distribution (CDN) managed by CKEditor or a self-hosted distribution that you run on your own infrastructure.

🚀 How to Add Your License Key to the Editor Configuration Once you have your key ( 'GPL' or your commercial key), applying it is simple. The licenseKey property must be included in the editor's configuration object during initialization. Basic Configuration Example Here is a typical example of how to set the license key in a classic editor setup: import ClassicEditor from 'ckeditor5'; import { Essentials, Paragraph, Bold, Italic } from 'ckeditor5'; ClassicEditor .create(document.querySelector('#editor'), { licenseKey: 'YOUR_LICENSE_KEY', // <-- Place your key or 'GPL' here plugins: [ Essentials, Paragraph, Bold, Italic ], toolbar: [ 'undo', 'redo', '|', 'bold', 'italic' ] }) .then(editor => { console.log('Editor was initialized', editor); }) .catch(error => { console.error(error); });
For a quick start via CDN, the configuration looks similar, as shown in the official quick start guide. Important Note for Integrations (e.g., Angular) When working with CKEditor 5 in frameworks like Angular, you must ensure the licenseKey is set correctly within the config object passed to the editor component. Setting it incorrectly can lead to "Template Invalid License key" errors.

Here are some of the most common issues and how to resolve them. | Error | Cause & Solution | | :--- | :--- | | license-key-invalid-distribution-channel | This often occurs when a license key is used with an incompatible editor distribution. For example, a trial key might be used with a self-hosted setup, or there's a mismatch between the channels (cloud vs. npm). Ensure you are using the correct key for your specific distribution method. | | license-key-domain-limit | Your commercial license key is tied to a specific set of domain names. This error means you are trying to use the key on a domain that is not on your allowed list. Log in to your dashboard to manage the domains associated with your license key. | | license-key-plugin-not-allowed | This happens when your license key does not include permissions for one of the premium plugins you are trying to load (e.g., FormatPainter ).

It means the licenseKey property is missing from your configuration, or the provided key is an empty string or an invalid format. Ensure you have included the property with a valid commercial key or the 'GPL' string. | search results have provided some initial information
❓ Frequently Asked Questions (FAQ) What happens if I use the 'GPL' key for a premium feature? If you use the 'GPL' key but attempt to load premium plugins, you will encounter the license-key-plugin-not-allowed error, as the GPL license does not cover commercial features. Is the license key required for on-premises installations? Yes, for any installation using premium features, a license key is required. The good news is that the on-premises version does not require a constant internet connection for the editor to function, though periodic online validation may be needed for premium services, depending on your plan. When did the license key become required? The config.licenseKey property became a mandatory requirement with the release of CKEditor 5 v44.0.0 . Users upgrading from older versions must add this property to their configuration. What is the CKEditor 5 LTS Edition? The Long-Term Support (LTS) Edition is a paid add-on for enterprise customers who need extended maintenance, security updates, and critical compatibility fixes for up to three years without breaking changes. It is only available under a commercial license. Can I upgrade my plan or get a different license? Yes. Many plan changes can be managed directly in the Customer Portal. For more complex changes, you can contact the CKEditor support team for assistance.
