Securely integrate collaboration features into business web apps
Many businesses rely on multiple 3rd-party tools to enable real-time collaboration in remote or distributed workflows. Collaboration Engine provides developers with everything necessary to productively and affordably build these features directly into custom business applications. This means simpler workflows, superior UX and complete control over sensitive data.
Users can collaboratively edit content, keep track of other active users and avoid conflicts while editing forms.
Users can hold real-time discussions, leave comments and keep track of recent edits to any component or view.
End users can selectively subscribe to and get real-time push and email notifications about changes and edits.
Get acquainted with Collaboration Engine
Collaboration Engine provides the server logic that synchronizes user-state and data across multiple client instances of a web app in real time. It can be hosted on any on-premise server.
Collaboration Engine also ships with:
- An intuitive, high-level API tailored for specific use cases.
- Low-level Topic APIs that offer more fine-grained control over its features.
- The Collaboration Avatar Group component that populates an avatar group with all the people present in the view, component or application.
- A Collaboration Binder, which allows everyone active in a form to see the real-time activities of other users, and shares values among users.
A few lines of code— a fraction of the time
Collaboration Engine is easy to set-up and integrate into new or existing Vaadin projects. Use the Collaboration Avatar Group component to display active users in a specific area of the application, and simply subscribe any Vaadin UI component, view or application to a collaboration topic, using the API to enable collaboration capabilities.
On-premise hosting for absolute security
Collaboration Engine can be hosted on any on-premise or cloud server that supports Docker. This means that sensitive data never leaves your servers, making it easy to ensure regulatory compliance and data security. In addition, Collaboration Engine is suitable for intranet or offline usage, and supports a wide range of access control and security options.

End-to-end support for your application
Our extensive free and commercial support services cover all aspects of the Vaadin platform— including Collaboration Engine. If something goes wrong, we have your back.
Excellent user experience by default
Pre-defined behaviors and UX patterns that are easy to tweak, provide a solid foundation for building market-leading collaborative solutions for employees and customers.
Developing with Collaboration Engine is free.
You only need a license when taking your application into production.
Start for free with 10 end users / month , and scale with a commercial license.
10 End Users / Month
|+ Up to 10 end users per month in production|
|+ Enable Collaboration Engine only for select end users|
|+ Upgrade to a commercial license at any time|
|+ Can be used with open-source Vaadin Core|
How many free end users do I receive with my Vaadin subscription?
Pro subscribers get 10 bundled end users per developer seat.
Prime subscribers get 25 bundled end users per developer seat.
Enterprise subscribers can negotiate a custom quota.
For example: This means that a Prime subscription with 5 developer seats, would receive a free monthly quota of:
25 users x 5 = 125 users
Can I purchase Collaboration Engine licenses for only the subset of users who need collaborative features?
Yes. You can purchase Collaboration Engine licenses for only the users who need to actively use collaborative features.
Developers can also choose to enable collaborative features in specific UI components or views. In addition, they can use code to selectively use either CollaborationBinder or Binder depending on the details of the end-user.
What happens to users who are not using collaboration features? Are they still able to use an application that includes functionality provided by Collaboration Engine?
If a user who has not been assigned a license interacts with a Collaboration Engine-powered component or view, they are presented with a regular, non-collaborative version of the component or view.
How is the usage of end-users calculated? Is it calculated per collaboration "topic", or the overall users of an application using collaboration features in a month?
The usage is calculated based on the total number of unique user ids encountered by the engine during the calendar month. It is not "per topic".
How can I upgrade my end-user limit?
At present, please contact our team to upgrade your end-user limit. We are currently looking to add a self-service option to make upgrades more convenient in the future.
Will my application break if I go over the monthly end-user limit for Collaboration?
Your application will not break / be rendered unusable if you go over your limit. Instead, end-users over the limit will be assigned to separate "Topics", which will provide a non-collaborative experience similar to the regular Binder.
How long do I have to upgrade my user limit when I go over the end-user limit?
We offer a 30 day grace period the first time you go over the limit. During this grace period, you will receive notifications reminding you to upgrade your limit. Collaboration Engine and your application will function normally. The grace period is reset upon upgrading, or on a yearly basis.
Is Collaboration Engine an integrated part of the Vaadin platform?
At present, Collaboration Engine is distributed as a separate package. This means that the relevant dependency must be added to the pom.xml file of the application. Integration into the Vaadin platform is being considered and may be available in later versions.
Do I need an active Vaadin subscription to use Collaboration Engine?
Yes, at present Vaadin Plus, Pro Prime and Enterprise subscribers have access to Collaboration Engine. Each subscription gets a free quota of end-users, as described in the pricing section of this page (above). To request access, please click here.
We plan to make a limited version of Collaboration Engine available to all users without a commercial subscription who have a Vaadin account in the future.
Do you offer a free trial of Collaboration Engine?
Collaboration Engine is billed per end-user (it is a run-time offering). All Vaadin users with any commercial subscription (Vaadin Plus, Pro, Prime and Enterprise) receive a free quota of users each month (see the pricing section above). Additional quotas of end-users can be purchased as required, based on the monthly users who use collaboration features in your application.
Is Collaboration Engine stable, feature-complete and ready for production usage?
Yes. It has been extensively tested and is ready to be used in production. It is also feature-complete, in that it enables collaborative editing, but additional functionality will be introduced regularly over the coming months. For more information, please see our roadmap.
Does Vaadin host a cloud version of Collaboration Engine that I can subscribe to?
At this point in time, we only offer a self-hosted version of Collaboration Engine. A cloud version may materialize at a later stage.
Which servers support hosting the Collaboration Engine?
During the phase 1 beta (available now), Collaboration Engine can only be deployed directly on the application server (in-memory).
Starting with phase 2 (available Q2 2021), Collaboration Engine can be deployed to any server capable of running a Docker image. See our roadmap for more information.
What impact does enabling collaboration features have on my application server?
We estimate that up to 100,000 users should have no discernable impact on the performance of your application server. Advanced performance and scalability testing is currently underway. More information will be provided as it becomes available.
What programming languages does Collaboration Engine support?
Collaboration Engine initially ships with a Java API (Vaadin Flow). However, a TypeScript API (Vaadin Fusion) will be introduced by Q4 2021.
Which Vaadin version should my application be built on to use Collaboration Engine?
Any application built on Vaadin 14.3 and above (LTS track) or Vaadin 17 and above (non-LTS track) is compatible with Collaboration Engine.
