## What it is
Vaadin Framework 6/7/8 is a Java web application framework that lets developers build modern web UIs entirely in plain Java, using GWT for the client side. This repository is now an archive of the last Apache-2 licensed versions (8.14.3 and 7.7.17), with newer development moved to a closed-source commercial model.

## Use cases
- build web apps in pure java without javascript
- maintain legacy vaadin 7 or vaadin 8 application
- fork vaadin 8 to self-maintain an enterprise app
- build data-centric internal business ui in java
- migrate old vaadin framework project to newer vaadin platform

## When to choose
- you have an existing Vaadin 7/8 codebase to maintain or fork
- you want the last open-source Apache-2 licensed Vaadin versions
- your team writes only Java and wants server-driven UIs

## When to avoid
- you are starting a new project - use the actively developed Vaadin platform instead
- you need open-source licensing beyond 8.14.3 / 7.7.17, since later releases are commercial
- you want a JavaScript/TypeScript-first frontend stack
