Do I need a production "license" from Vaadin to deploy my Vaadin -Spring Boot war to local Tomcat?
When I run mvn -P production it automatically tries to connect to a Vaadin server.
Some questions a) Was I wrong in my interpretation of Vaadin being an open source framework b) If I eventually have to deploy my war on cloud, are there Vaadin costs apart from the cloud provider?
