Cloud Services - overview
CKEditor Cloud Services is a cloud platform for editing and real-time collaboration services.
The information in the guides applies to the cloud version as well as the On-Premises version.
More information about the On-Premises version can be found in the On-Premises section.
# Cloud vs. On-Premises
CKEditor Cloud Services is available in two variants.
The first of them is Software as a Service (SaaS). In this variant, CKSource takes care of all the needed infrastructure, adjusts the servers to the current needs, ensures data safety as well as performs and restores backups in the case of any losses. After completing the purchase, the customer can log into the CKEditor Ecosystem customer dashboard where they can find all the credentials needed to get up and running with CKEditor Cloud Services. The SaaS environment runs on the AWS infrastructure, which allows us to keep the availability on a high level. You can read more about server security on the security page.
The other approach is On-Premises, where CKSource provides only the software. It is the customer that is responsible for the installation, provision and maintenance of the servers. In addition, the customer needs to monitor the servers, scale the application in response to the increased usage, as well as take care of creating and restoring backups. Before running CKEditor Cloud Services for the first time, the customer needs to prepare the whole environment, which requires additional work by developers.
# Updates
New features and fixes are applied to SaaS immediately after being tested, while the On-Premises Docker images are released periodically every 6 weeks and the On-Premises installation has to be updated manually.
# Support and monitoring
Irrespective of the chosen CKEditor Cloud Services variant, CKSource customers are always provided with top-quality assistance. Thanks to the robust monitoring system, the CKSource team is able to swiftly debug SaaS application problems. Support for On-Premises is also provided but, due to the infrastructure being managed on the customer’s end, it requires closer cooperation between CKSource and the client team.

# Real-time collaboration
CKEditor Cloud Services offers a fast and highly scalable service for real-time collaboration, compatible with rich text editors built on top of CKEditor 5 Framework. It is capable of handling real-time collaboration on text documents and tracking users connected to the document. It also serves as a storage for comments added to the document.
Apart from having a supporting backend to transmit operations, resolve conflicts and apply changes between users connected to the same document, some features are needed on the client side to offer a full real-time collaboration experience:
- Showing multiple cursors and selection coming from other users.
- Showing users connecting to and disconnecting from the document.
- Offering the UI for managing comments and markers in the document.
CKEditor Ecosystem offers a collection of plugins that can be integrated with any CKEditor 5 build to provide a fully flexible and customizable experience – the CKEditor 5 Collaboration Features.
# CKEditor 5 Real-time collaboration features
CKEditor 5 Real-time collaboration features let you customize any CKEditor 5 build to include real-time collaborative editing, commenting and track changes features and tailor them to your needs.
Real-time collaboration consists of four features delivered as separate plugins that can be used with any CKEditor 5 build:
- Real-time collaborative editing – Allows for editing the same document by multiple users simultaneously. It also automatically solves all conflicts if users make changes at the same time.
- Real-time collaborative comments – Makes it possible to add comments to any part of content in the editor.
- Real-time collaborative track changes – Changes to the content are saved as suggestions that can be accepted or discarded later.
- Users selection and presence list – Shows the selection of other users and lets you view the list of users currently editing the content in the editor.
All of the above features are customizable. This makes implementing real-time collaborative editing within your application a highly customizable out-of-the-box experience.
