: If the free tier doesn't meet your needs, you can choose from predefined plans on the pricing page . For self-hosted deployment or custom requirements, contact the sales team.

Once you have purchased a commercial plan, accessing your license key is easy.

: Your commercial plan or the free plan has a limit on how many times the editor can be loaded, often tied to specific domains. When you exceed this limit, the editor will throw this error.

Install CKEditor 5 in your project:

Your entire application must also be open-sourced under a GPL-compatible license.

ClassicEditor .create( document.querySelector( '#editor' ), ', 'bold', 'italic', 'link', 'bulletedList', 'numberedList', 'blockQuote' ], ) .then( editor => console.log( 'Editor initialized successfully!' ); ) .catch( error => console.error( error ); ); Use code with caution. 2. React Integration

Have questions about the licensing model or key implementation? Drop them in the comments below!

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.

Because CKEditor 5 runs in the user's browser, the licenseKey configuration property is inherently visible in the frontend JavaScript source code. This is normal and expected by CKEditor. The key itself is bound to your specific domain names or account ID, meaning someone else cannot easily steal your key and use it on an unauthorized domain without triggering compliance flags on CKEditor's backend tracking. Is there a perpetual license for CKEditor 5?

To recap the practical steps:

There is no separate key to "obtain" for the open-source version. Instead, you simply use the string 'GPL' in your configuration where a license key is required. This is often referred to as a "GPL key" in community discussions.
