What is CheerpJ Applet Runner

The CheerpJ Applet Runner is a browser extension that allows users to run legacy Java Applets on modern browsers without a Java plugin or a local installation of Java

It works by converting the Java Applet to WebAssembly and JavaScript on the fly, providing a private and secure client-side solution

The extension is developed by Leaning Technologies, based on CheerpJ, a professional Java to HTML5 compiler

Fantastic job.

Cant say I can give a review on the extension fully when I have yet to see it working on any site I try to use it on. with changes google have made to stop supporting java this seemed like an ideal solution to get me back to what I was doing. as of now the sites that don't work continue to not work. hopefully this is not the case for others. 2 stars just because its useful to some people so it warrants a small token.
