CKEditor & add-ons pricing

Under which open source licenses are CKEditor 5 and CKEditor 4 available?

CKEditor 5 is distributed under a GPL 2+ copyleft license. For more details visit ckeditor.com/legal. Note, that if you are running an OSI approved project that is not compatible with GPL 2+ copyleft, find out more about our Free for Open Source offer: ckeditor.com/wysiwyg-editor-open-source/.

CKEditor 4 is distributed under three copyleft Open Source license options: GPL, LGPL and MPL.

What are the benefits of being commercially licensed for CKEditor?

Compared to Open Source which comes with a multitude of obligations, the obvious advantage is a legal one: commercial licenses do not require you to share your source code with the public in any way. Also, commercial licenses come with another equally important advantage: support. Our support team can make sure that you understand and integrate the editor correctly, and will be there to help in case you run into a wall.

What is an Active User?

Active User is a person or bot that used our software at least once in a given billing period. For example, if you purchased a pool of 25 Active Users and in the middle of the billing period (be it annual or monthly) and 2 of your users are no longer active, you may allocate these 2 slots to 2 new users of your application.

What happens if I exceed my active user allowance for CKEditor/CKFinder?

If you exceed your active user allowance for CKEditor/CKFinder, simply contact us at sales@cksource.com to talk about upgrading your allowance or customizing your plan.

What is a product or internal application family?

A product (OEM or SaaS) or internal application family cannot be treated as one even under one suite of software solutions. Each product or internal application within your family supports your users in a different area of the business and shall be licensed separately. If you wish to embed the editor in a product or internal application family solution, please contact us.

What is a Developer?

A Developer is an employee or individual contractor designated by you to perform development activities (coding, configuring, code testing) with our products or to receive ongoing technical support.

Is it possible to use a different licensing metric than the number of users?

We will be happy to discuss a suitable solution on a case-by-case basis in the Flexible plan.

What is the number of support requests per month?

The number of support requests per month is the total monthly allowance of support requests for the product bundle you purchased. The product bundle means any additional products you purchased with CKEditor (e.g. CKEditor and CKFinder, Accessibility Checker or CKEditor and Easy Image, etc.).

If you purchased CKEditor as a stand-alone product, the number of support requests per month refers only to the editor support.

What is the minimum length of subscription-based software licenses?

The minimum length of subscription-based license agreements for our software products (CKEditor, CKFinder, Accessibility Checker, Letters, CKEditor 5 Comments Plugin, CKEditor 5 Track Changes Plugin and Collaboration Server On-Premises) is 12 months regardless of which billing you choose (monthly or annual).

If you decide to terminate your subscription of CKEditor, CKFinder, Accessibility Checker, Letters, CKEditor 5 Comments Plugin, CKEditor 5 Track Changes Plugin and Collaboration Server On-Premises, you are obliged to immediately remove our software completely from your or your clients’ servers. That means that upon your cancellation you’re not allowed to distribute or commercialize our software as part of your Product or provide access to it via your Internal Application.

Do we count servers, environments or domains on which you host your products and internal applications?

Except for Collaboration Server On-Premises, we do not take into account these metrics. As long as you use our software in a defined product or internal application, you may deploy it on as many servers, environments and domains as you wish.

I am currently using CKEditor 4 in my project but want to migrate to CKEditor 5. Do I need to purchase a new license?

You do not need to purchase a new subscription when migrating to CKEditor 5 if:

• you are on an active CKEditor 4 subscription,

• you purchased the CKEditor 4 perpetual license and your license is renewed on a yearly basis.

What is the "Max image megapixels" limit in CKBox?

It specifies the maximum resolution of an image that can be uploaded or created. For example a sample 12MP image may translate into 4290x2800 pixel resolution while a typical 36MP image may have a 7360x4912 pixel resolution. A sample DSLR camera, Canon EOS 850D, creates 24.1MP images.

What is the "Max file size" limit in CKBox?

It specifies the maximum size of a file that can be uploaded.

How does the overusage works in CKBox?

If you exceed the monthly transfer limit or the storage limit we may issue an additional invoice for the overusage. Each plan has its own rate for the overusage. For example if in the Starter plan you exceed the monhtly bandwidth limit by 10GB and use 5GB of aditional storage (55GB in total), you will be charged 10*$0.6 + 5*$0.6 = $9.

What happens if I exceed the active monthly users limit for CKBox?

If we notice that the active monthly users is being permanently exceeded, we will contact you to propose the most optimal plan for your use case.

How is the storage calculated in CKBox?

We count the average monthly storage used by your account. So if you have a Starter plan with a limit of 50GB, store 10GB of files most of the time and have i.e. a one day peak usage with over 200GB of files stored, you will still be below the monthly storage limit.

When "Additional functionalities planned for the future" will be available in CKBox?

We plan to gradually add them until Q2 2023. If you are interested in prioritizing any specific functionality, contact us.

What is the minimum length of CKEditor Cloud Services subscriptions?

The minimum length of CKEditor Cloud Services subscriptions (such as CKBox, Export to PDF/Word or Easy Image) is one month. If you are interested in a much longer contract (such as 2 or 3 years), we are open to negotiate the price.

Where is your data center located?

CKEditor Cloud Services are hosted on Amazon Web Services (AWS), which provides an exceptional security and stability. The data center is located in US East.

CDN used by CKBox and Easy Image is powered by Amazon Cloudfront, offering over 400 edge locations across every continent around the world.

How the Export to PDF/Word services are processing my data?

Export to PDF/Word are services that generate PDF/Word files based on the data provided by the customer (HTML, CSS). To perform the conversion, they require the data sent from the editor or a database, but the services themselves are fully stateless.

The sensitive data (HTML, CSS, comments) is used only during the processing and then removed from the servers after the document is created and returned to the user.

All data transmission between CKEditor / Customer's application and CKEditor Cloud Services infrastructure is encrypted with TLS 1.2+.

What happens if I exceed the limits of the (free) Personal CKBox plan?

The Personal CKBox plan is a special free plan for exploring CKBox and for websites that do not require significant bandwidth or storage. If you exceed the storage limit, we may block the upload functionality and ask you to clean to free up the space and go back below 2.5GB. If you exceed the allowed bandwidth per month, we may stop serving your images via CDN until the end of a 30-days "billing cycle". The free accounts that will permanently exceed the allowed limits may get suspended.
