For some customers, their user environment may not have an outside internet connection or for security reasons, they prefer to be able to execute the Vizlib code fully on-premise behind their firewall.
Vizlib Enterprise customers have the option to upgrade their package to download the extensions for use in On-Premise Mode, which means no API call is required to validate the extension usage. Furthermore, Vizlib Offline also works with the offline mode provided in the iOS app.
When you are installing the on-premise mode of Vizlib, no automatic updates can be pushed to your environment. It's in your responsibility to regularly check for the latest version, updates, and releases.

For continuous integration, you have the ability to integrate the Vizlib Extension Library with Jenkins. For more information about this, please read this article here:
