CKEditor 5 — License key (concise digest)

Summary

• CKEditor 5 is dual‑licensed: open‑source under GPL 2+ (GPL) or via commercial licenses. A commercial license removes GPL restrictions, enables white‑labeling, self‑hosting, premium features and paid support.
• A license key (string) is required to activate commercial/premium features and certain distributions; for GPL use you may set licenseKey: 'GPL' in configuration.

How licensing choices affect you

• GPL (open‑source) usage:
  • Allowed if your project is GPL‑compatible (or you accept GPL terms).
  • Editor will show a small “Powered by CKEditor” attribution.
  • Some premium features and self‑hosted commercial distributions are not available.
• Commercial license:
  • Removes GPL obligations and attribution (white‑labeling on paid plans).
  • Enables premium features (collaboration, import/export, AI, CKBox, etc.), self‑hosting, support, LTS.
  • Offered as cloud (CDN, usage‑based) or custom self‑hosted plans.

Types of license keys and plans

• GPL key: use value 'GPL' to run the open‑source edition (no account needed or via legacy GPL account).
• Free commercial plan: limited cloud plan (e.g., small monthly editor‑loads and limited features).
• Trial/evaluation keys: short‑term keys (trial or demo) for testing—follow CKEditor trial signup.
• Production commercial keys: obtained via pricing page or sales; used for cloud or self‑hosted plans; same key covers standalone premium features listed in dashboard.
• LTS / enterprise: commercial-only distribution and support for extended maintenance.

How to get and activate a license key

• For commercial/trial: sign up in CKEditor Ecosystem/Customer Portal or contact sales; start 14‑day trial without a credit card.
• From dashboard: copy license key for your subscription/product.
• Add to editor config (example):

  ClassicEditor.create( document.querySelector('#editor'), 
    licenseKey: '<YOUR_LICENSE_KEY>' // or 'GPL'
    // ...plugins, toolbar, etc.
   );
  

• Some premium services (document converters, CKBox) also require server-side authentication/config per their guides.

Distribution choices (impact on licensing)

• Cloud (CDN): easiest to deploy, usage‑based billing; commercial cloud plans available.
• Self‑hosted: requires commercial plan for certain premium features and white‑labeling; contact sales for custom terms.

Notable legal/compatibility points

• CKEditor 5’s open source distribution is GPL 2+; if your project's OSS license is incompatible, contact CKSource for an appropriate OSS arrangement.
• Certain LTS‑only builds are available only under commercial terms (not GPL).
• Pricing, plan features and attribution rules can change — consult CKEditor’s licensing/pricing pages or sales for binding terms.

Quick action checklist

1. Choose GPL if your project accepts GPL and the attribution is acceptable.
2. If you need premium features, white‑labeling, self‑hosting or commercial assurances, purchase a commercial plan or start the free trial.
3. Get the key from the Customer Portal or sales, then set licenseKey in your editor config.
4. For server‑authenticated features (converters, file manager), follow the feature‑specific activation guides.

The Open Source vs. Commercial License Nuance

CKEditor 5 is built on a "dual licensing" model: CKEditor 5 — License key (concise digest) Summary

• GPLv2+ (Open Source): You can use the core editor for free, but your entire application must also be released under an open-source license. If your application is not open source, the GPL license "infects" your code.
• Commercial License (Paid): You pay a fee to receive a license key. This allows you to keep your application proprietary, closed-source, or commercial.

Key Takeaway: You do not need a license key for the free, open-source version. You do need a CKEditor 5 license key to legally run the editor in a commercial, closed-source project or to use premium plugins.
