Problem or Opportunity
1. It does not support WebGL. 2. ES6 is not supported. 3. Performance is "as is" because of runtime limilation. 4. AudioContext API exists, but it does nothing. 5. Currently, drawing engine is GDI/WinForm. I am considering port to Xamarin.Forms or Eto Forms or others to run on .net core in Linux, OS X.
Solution (product or service)
There is no web browser which can run on any platform regardless of CPU architecture. Java does also not have fullspec browser engine (Hotjava is dead).
No competitor in terms of 'cross platform'. WebKit is fast, but it is native image for each cpu and os platrorm.
Advantages or differentiators
Debugging is relatively easy. Adding new API is very simple.
