Applet on an Internal Network or Business use?
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 licence CheerpJ, please get in touch.
Leaning Technologies coupled their clear ability to extend their toolset to support the ultimate software challenge with an unwavering determination to achieve the level of perfection required. After an intense but relatively short period, Blackbird was able to ship our [HTML] product to clients globally.

How does the CheerpJ Applet Runner work?
The CheerpJ Applet Runner 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.
