Here at Leaning Technologies, we use WebAssembly daily to create unique and seemingly impossible technologies, like CheerpX (a WebAssembly virtual machine designed to safely run arbitrary x86 libraries and applications in browser) and CheerpJ (a solution to compile and run Java applications in the browser).

CheerpX, in particular, is certainly the most complex JIT engine written in WebAssembly, and quite possibly the single most advanced WebAssembly project running in the browser.

In order to efficiently run arbitrary x86 code in WebAssembly, we have overcome all sorts of limitations, caused either by the current state of the Wasm standard, or by the browser implementations. If you are interested in reading more about the magic behind CheerpX, we published some information in the previous article of this series, and in a presentation back in February at the Wasm SF meetup.
