HBrowser

HBrowser

Headless/full Java browser with support for downloading files, working with cookies, retrieving HTML and simulating real user input. Possible via Node.js with Puppeteer and/or Playwright. Main focus on ease of use and high-level methods. Add this to your project with Maven/Gradle/Sbt/Leinigen (Java 8 or higher required).

try(PlaywrightWindow window = HB.newWin()){
    window.load("https://example.com");
   // ...   
}

All examples here. Note that the first run may take a bit because Node.js and its modules get installed into your current working dir under ./headless-browser.

Features

• High-Level methods for...
  • downloading files.
  • working with cookies.
  • retrieving HTML.
  • simulating real user input.
• Integrated evasions for headless detection: HB.newWinBuilder().headless(true).makeUndetectable(true)...
• Easy access to Node.js from within Java: new NodeContext().executeJavaScript("console.log('Hello!');");
• HTML handling via Jsoup and JSON with Gson.

How good are the evasions?

try (PlaywrightWindow w = HB.newWinBuilder()
     .headless(true).makeUndetectable(true).buildPlaywrightWindow())
{
    w.load("https://infosimples.github.io/detect-headless/");
    w.makeScreenshot(new File("screenshot.png"), true);
} 
catch (Exception e) {e.printStackTrace();}

Drivers

Playwright is the default and recommended browser driver to use, since it supports downloads and more of its features were ported to Java. Checkout JG-Browser for a browser completely written in Java.

Name	JS-Engine	Downloads
Playwright	Node.js/V8	Yes
Puppeteer	Node.js/V8	No

You can find their versions in this class, which also allows you to set custom versions. (JS = JavaScript; Downloads = If the browser is able to download files other than html/xml/pdf;)
