Wasn't there some Wasmer controversy with the CEO or founder or something last year? Not trying to disparage the company or their work, I was just reminded of it by this post.
A particularly damning incident was the time they tried and failed to trademark "WEBASSEMBLY", an open W3C standard [2] [3]. There are many choice words for companies trying these kinds of stunts.
Webassembly is growing despite Wasmer's existence. Not because of them. Be cautious.
