Polyglot Low-Code Web Applications

Netuno is written in Java and runs in GraalVM to facilitate web application development, it currently suppports the following programming languages:

• JavaScript/ES6
• Groovy
• JRuby (Ruby)
• Jython (Python)
• Kotlin

😎 While you are programming you won't need to restart the server to compile the newly updated code.

All log outputs such as server-side, client-side (NPM run watch) and other outputs are integrated in the same console. By having this feature you'll only need to look to one console thus easing your work.

Build Requirements

• Linux, macOS and Windows;
• Maven
• NodeJS
• Java 11
