What is the license model for the Vaadin platform?
Do Vaadin Pro and Prime include access to all current and upcoming versions of commercial components?
Can I buy separate licenses for different tools?
How does the 10 years extended maintenance work?
Sometimes, migrating to newer Vaadin versions is not feasible, and it makes more sense to keep your business-critical app running on earlier versions. Prime (and higher) customers enjoy a 10-year extension to the official support period. For example, Vaadin 7 official support ended in Feb 2019, but with this extension, you have support until 2029.
See more details in the fact sheet.
How many licenses do I need?
All developers contributing to a project that uses any of the commercial products need to have a valid license.
In addition to the developer licenses, Collaboration Engine is also billed per the number of end-users. The subscriptions include a complementary end-user quota. See details on the Collaboration Engine pricing FAQ.
