CheerpJ Applet Runner
Run Java applets without installing Java
CheerpJ Applet Runner - Run Java applets without installing Java
With the CheerpJ Applet Runner extension, you can run legacy Java Applets on modern browsers without a Java plugin or a Java installation.
Using the CheerpJ Applet Runner is simple. Just install and pin the extension. Next, visit your Applet-based website, click the extension icon in the upper-right corner of your browser, and then press the 'Enable' button in the popup. Once enabled, the extension is activated for the current domain, and Applets will start automatically if they are present.
This extension works by 'converting' the Java Applet to WebAssembly and JavaScript on the fly. It is private and secure, runs fully client-side (i.e. it does not contact any server), and does not collect any data or analytics at all. All your data, as well as your application are kept within the boundaries of your browser.
This extension, developed by Leaning Technologies, is based on CheerpJ, a JVM/JRE replacement for modern browsers. More information on CheerpJ are available at https://www.cheerpj.com.
This software is free to use for non-business purposes on public-network Applets. For any other use, such as internal network applets, or if you are a company or public-sector organisation and would like to license CheerpJ, please get in touch with [email protected].

This has finally managed to solve a problem I've been struggling to solve for quite a long time. The online AbDesigner tool failed to download the dat file so i couldn't see the results either online or on the heatmap viewer (downloaded for offline viewing). Now i can continues checking proteins for epitope and antibody designing :-)
Excellent. Great job.
Works great
awesome, this applet runner made my day. now i can use my old applet based website again.
Excellent!
This applet runner allowed me to use the java based web configurator on an old procurve switch. Top Drawer!!

Incredible work. I thought Applets were lost forever!
Amazing, working!
Nice to be able to see my java sites again after years of no access. BRAVO
Not working on actual Applet based website. Try this on https://ireps.gov.in/appletTest.html. Not working on this website. However this website (https://ireps.gov.in/appletTest.html) is working on Microsoft Edge in IE mode.

Nice but some of the applets I want don't work (maybe because they use opengl?)
nice
Some Java Applet works and others don't. I send report to verify how to resolve the problem. Thanks

The Java Applet I am using looks and behaves very similarly under CheerpJ on a modern computer, vs an ancient computer with an old browser that actually runs Java applets. Performance is good, too. Five stars! Note: You do have to explicitly enable CheerpJ every time you visit a page with an applet.
Simply amazing semplicity and effectiveness. Very useful with old switches that only have a Java Applet interface and other similar appliances. Great job!

Does not work when a second window is opened from the original applet, have to kill the browser tab to progress.
