Not sure what language you are using but CEF was good for Chrome under C#. Might be available under C++ too I think. There was an equivalent Gecko one for Fire

Not sure what language you are using but CEF was good for Chrome under C#. Might be available under C++ too I think. There was an equivalent Gecko one for Firefox but I could never get it working correctly so deferred to CEF under Visual Studio (think there's a nuget package for it, conveniently). Also wxWidgets under C++ offers ability to host a local WebView instance or Trident with wxWebView.
