BlueWorx delivers end users the same Fiori user experience (UX) as SAP delivered Fiori applications. That's because it uses the SAP provided SAPUI5 libraries. It's just technically delivered from inside SAP using Neptune Software's SAP Certified Add On. 

We have multiple customers using applications developed using Neptune Software their SAP Fiori Launchpad right alongside SAP delivered Fiori applications ... they can't tell the difference, and don't care, because the user experience is the same.
