At GitHub - crs4/openEHRTool-v2: New version of openEHRTool completely rewritten you can find the new release of the openEHRTool which is a free open source frontend developed at CRS4 for EHRBase. It has all the user and administrator REST API endpoints and in addition some useful new ones (e.g., upload a list of compositions and create a different EHR on the fly for each of them). Pictures of the tool are found in the github main page a linked above.
The project is still in development as the forms are not implemented yet.
I hope you like it as much as I loved to code it
