Vaadin is an open-source web framework for rich Internet applications. In contrast to JavaScript libraries and browser-plugin based solutions, it features a server-side architecture, which means that the majority of the logic runs on the servers. Ajax technology runs on the browser-side to ensure a rich and interactive user experience. On the client-side Vaadin is built on top of and can be extended with Google Web Toolkit.
Vaadin uses Java as the programming language for creating web content. The framework incorporates event-driven programming and widgets, which enables a programming model that is closer to GUI software development than traditional web development with HTML and JavaScript.
Vaadin uses Google Web Toolkit for rendering the resulting web page. While the way Vaadin uses Google Web Toolkit could lead to trust issues – it only operates client-side (i.e., in a web browser's JavaScript engine) – Vaadin adds server-side data validation to all actions. This means that if the client data is tampered with, the server notices this and doesn't allow it.
Vaadin's default component set can be extended with custom GWT widgets and themed with CSS.
