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.
# Easy Image
Easy Image is a service that takes care of image uploads. It reduces the effort required on your part to build a complete modern editing solution with support for embedding images.
Easy Image guarantees that all images inserted into your content are responsive. With a single image upload, several optimized versions of the image are created after upload by CKEditor Cloud Services, for different sizes of displays. All this is transparent to the end user who uploaded the image. Rescaled and optimized images are delivered through a blazing-fast CDN.
It works with both CKEditor 4 and CKEditor 5 WYSIWYG editors, as well as Letters.
Refer to the documentation for details.
# 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 two solutions for implementing real-time collaborative editing:
- CKEditor 5 Collaboration Features — A collection of plugins that can be integrated with any CKEditor 5 build to provide a fully flexible and customizable experience.
- Letters — A ready-to-use real-time collaborative editor with all the essential 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.
