CheerpX is x86 virtualization to run executables and OS client-side

The description is very perplexing. Especially the "entirely client-side" phrase. Isn't that how VMs normally work? Looking at it further, this has very little to do with "virtualization". It's just another emulator.

  In addition to your points, I can't figure out the licensing - they state that CheerpX is a commercial product, but I am unable to find any information about paid or free usage tiers... Or maybe I just didn't dig deep enough...

    Not sure if this is for all the products but this is found on the main page. Licensing Cheerp is free open-source software, actively developed and maintained by Leaning Technologies. Commercial support, feature fast tracking, sponsored development and consulting packages are available for Enterprise customers.

      Looks like all the products have a different licenses https://cheerpj.com/licensing/ https://cheerpj.com/licensing/ The X version seems to be minified CDN hosted .js file but no other info about usage. The only comment in the file indicates that its some sort of C/C++ file presumable ported over to JS /Compiled using Cheerp (R) by Leaning Technologies Ltd/

I stumbled upon Leaningetch in the past looking for a way to compile Java to JavaScript. This is a company that found a niche in "modernizing" old software, like, serving customers that still have mission-critical software written as a C++/MFC or even Java Applets and help them keep that software alive. There's nothing wrong with their niche, but I feel like there's a big disconnect to what could be attractive to the HN crowd.

  What alternate business model would you employ if you ran Embarcadero?

    Hmm I missed your question but I just don’t think commercial, closed source compilers are a good idea. It seems they are doing good with their business models so I wouldn’t ask them to change anything, but I think it would be cool if the compilers and ide were free and they sold libraries.

As discussed on the front page last week emulating Linux syscalls, it took a while to notice it's closed source. WebVM is a server-less virtual Linux environment running client-side https://news.ycombinator.com/item?id=40940225 https://news.ycombinator.com/item?id=40940225
