Do you think we are missing an alternative of Vaadin or a related project?
Vaadin allows you to build modern web apps efficiently in plain Java, without touching low level web technologies.
This repository contains source code and issue tracking for Vaadin 8 and Vaadin 7, both of which use GWT as the base of client-side implementations. You can find source code and issue tracking for newer, web component based Vaadin versions in vaadin/platform.
Vaadin 8 includes Vaadin 7 compatibility classes and is supported until February 21, 2022 (extended support will be available for ten years after that).
Vaadin 7 support has already ended, extended support is available until February 2029.
