Which tools enable non-developers to create low/no-code extensions?

The correct answer is SAP Fiori extensibility apps because these tools are specifically designed to allow non-developers to extend and customize SAP Fiori applications without needing deep programming knowledge. They provide a user-friendly interface for users to modify UI elements and logic through configuration and visual design tools. This empowers business users and process owners to tailor applications to their specific needs, enhancing usability and functionality without writing complex code.

While SAP Build and SAP Business Application Studio also support low-code or no-code development, they are generally more complex and geared towards both developers and non-developers, providing a broader range of capabilities that may require some level of technical knowledge to leverage fully. On the other hand, the SAP Cloud SDK is primarily aimed at developers to facilitate integration and development tasks, thus not fitting the criteria of being particularly user-friendly for non-developers.
