Here are over a dozen TeaVM-based projects, for inspiration: https://www.frequal.com/TeaVM/TeaVmBasedSites.html

Several use cases where TeaVM shines:

* A developer or team has strong Java skills and wants to develop single-page apps

* A Java desktop project wants to move to the web and has lots of validation logic they don't want to double-maintain in Java and ECMAScript/WASM

* A Java-based game developer wants to make a Canvas-based version of their game for the web (potentially full-screen)

* A Java developer wants a batteries-included framework for web development. TeaVM comes with a minifier, tree-shaker, packager, and more, out of the box, with familiar 'mvn clean install' semantics (And Gradle support too).
