Knowledge Base Navigator

Official Content
This documentation is valid for:

The GeneXus Knowledge Base Navigator (KBN) is an iOS native application that allows GeneXus users to prototype the iOS online applications they create using GeneXus. It allows exploring the functionalities that a GeneXus Knowledge Base application exposes: Entities and Relationships.


You can download the KBN from the Apple Store.

Known limitations

To prototype an application that uses any of the following features, a compiled application is required.

Offline generated code

Offline applications cannot be prototyped with the KBN. This tool only supports interpreted metadata.

Calling offline objects (that is, objects with the Connectivity Support property set to Offline) is not supported either.

User Controls and External Objects

Custom User Controls (or the standard AnimationView User Control) and External Objects are not supported in the KBN; only those provided natively by GeneXus can be used.


Push notifications will not work when prototyping in the KBN.


Embedded resources will not work when prototyping in the KBN. That includes:

  • Embedded fonts; a default Helvetica font will be used instead;
  • Images with varying resolutions are not supported;
  • Other embedded resources will not work either; for example, custom Lottie animations.
