Based on aggregated data from actual buyers, CKEditor 5 commercial licenses typically range from:
Your project is proprietary, commercial, or closed-source (you cannot or will not release your code under GPL).
What are you using? (React, Angular, Vue, or vanilla JS?)
You can generate multiple keys for different environments (development, staging, production) from the same license.
The licenseKey property is entirely missing from your configuration object.
If your project is fully open-source (GPL-compliant) but you want advanced features like real-time collaboration, track changes, or export to PDF, CKEditor offers a free tier.
Hello from CKEditor 5!
// In your code config: licenseKey: process.env.LICENSE_KEY
Using CKEditor 5 without a license key in a closed-source commercial app is a copyright violation. The CKEditor team actively enforces their licensing.
For production license keys, the Customer Portal offers an optional feature. This security enhancement allows you to restrict editor usage to specific domains or IP addresses, preventing unauthorized use of your license key.
ClassicEditor.create( document.querySelector( '#editor' ), licenseKey: 'Your-License-Key-Here', plugins: [ ExportPdf, /* others */ ], toolbar: [ 'exportPdf', 'bold', 'italic' ] );
If your project is GPL-compatible, no account or key retrieval is necessary. Simply set licenseKey: 'GPL' in your editor configuration, and you're ready to go.
Choosing the open-source route means your entire application's source code must also be made publicly available under a GPL-compatible open-source license. If you cannot disclose your software's source code, you cannot legally use the 'gpl' license key string. 3. Commercial CKEditor 5 License Keys
