## What it is
GWT (Google Web Toolkit) is an open-source SDK that lets developers write client-side web applications in Java and compile them to optimized JavaScript. It includes a compiler, core Java API libraries, UI widgets, RPC support, and development tooling for building and debugging browser-based applications.

## Use cases
- write web apps in java instead of javascript
- compile java to javascript for the browser
- build ajax applications with java tooling
- debug browser apps in a java ide
- build cross-browser ui widgets in java
- migrate a legacy java web frontend

## When to choose
- your team is Java-expert and wants type-safe client code
- you maintain or extend an existing GWT application
- you want a single language across client and server with GWT RPC

## When to avoid
- you are starting a brand-new modern frontend project (React/Vue ecosystems are far more active)
- you need a large ecosystem of modern JS libraries and tooling
- you want server-side rendering or SEO-heavy pages

## Facets
- artifact type: framework
- maturity: maintenance
- function: compiler, web-framework, ui-components, rpc, internationalization, testing, sdk
- domain: web-development, frontend, developer-tools, cross-platform
- platform: jvm, browser, cross-platform
