This is a curious project I found out randomly (well I was looking at plantUML JS demo and wondered how they managed to get Java code to run in browser).

Note that this is a proprietary software, that can be used for non-commercial purposes for free.

They also have a Chrome extension that change java applets on any page to wasm+js.

The same company seems to offer “cheerpx for flash”, that runs flash in browser by running entire x86 virtual machine in wasm, and on that machine runs full official Flash runtime licensed from Harman.

I’m surprised that even works.
