I can only recommend against Awesomium. Their library has a lot of bugs which I can see past, but the way they support their product is repulsive. On average it took them 3-5 days to get back to us on a email ticket with a half-baked response that then took another 3-5 days to clarify. The founder didn't seem phased that this was a problem and had zero empathy that we had deadlines to meet and software to ship.

We ended up ripping out Awesomium from our product and replaced it with CefSharp. Now we don't get held up by Awesomiums crappy support because we can just fix our problems ourselves. We couldn't be happier. That said, it would be nice if there was commercial support for CefSharp. We have a team of full time native developers who have to deal with CEF issues that would be nice to put on somebody else's plate. Anybody know if there is such a thing?
