Vaadin Flow

Vaadin Flow is a new Java web framework for building modern web apps and websites. It is part of the Vaadin Platform and a successor for the Vaadin Framework bringing Web Component support to Java users. Flow allows developers to be super productive by creating UIs in Java or by using HTML Templates for composing the UI and binding it to any backend using Java.

The power of Vaadin Flow comes from the following concepts:

  • A set of beautiful UI components build with focus on end-user and developer experience

  • Powerful abstraction layers for easily building your own reusable UI components with either Java or HTML templates
