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 local installation of Java.

Using The CheerpJ Applet Runner is simple. Install the extension, visit your Applet-based website, and enable the extension by clicking on its icon on the upper right corner of your browser!

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 professional Java to HTML5 compiler. More information on CheerpJ are available at https://leaningtech.com/cheerpj/

This software is free to use for non-commercial 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].
