The Java-Graal Browser, is a headless browser with latest JavaScript support, completely written in Java.
JGBrowser browser = new JGBrowser();
try(JGWindow window = browser.openWindow()){
window.load("https://example.com");
// ...
}Even though this browser has latest JavaScript support, browsers like Google Chrome, Firefox etc. provide additional JavaScript APIs, called Web-APIs, which practically every modern webpage uses.
Since this browser is meant to be completely written in Java, we must also write/implement all of those Web-APIs by ourselves.
For one person alone that would take decades, that's why this project is designed in a modular way, so that everyone can add the functionality that he/she needs. See how-to-implement-a-js-web-api.md for details.
In short, in its current state, this browser will fail executing most of the JavaScript code that relies on Web-APIs at the moment.

HtmlUnit is good, but relies on another JavaScript engine with a lot less features that gets updated very rarely. Thus, this project exists. More details here, where I tried implementing GraalJS into HtmlUnit without success.
- Latest JavaScript support via GraalJS
- Easy HTML handling with Jsoup
- Easy Web-API implementation
- Completely written in Java
