Can a web app be shared from Portal for ArcGIS or ArcGIS Online without sharing the web map?

Answer

No, a web app cannot be shared independently without sharing the source web map it is created from, as it relies on the data and configurations of the source. Sometimes, sharing a web app without sharing the web map is preferable to avoid unnecessary changes to the source map. As a workaround, create a view layer as the source layer to restrict editing capabilities or adjust visibility while maintaining the functionality of the web app. Refer to the following documentation for more information:

• ArcGIS Online: Create hosted feature layer views
• Portal for ArcGIS: Create hosted feature layer views

Another option is to configure the hosted feature layer’s edit settings to limit editing on the layer. Refer to the following documentation for more information:
