How the Add-on Mart works

The PortaOne VAS solution stores code for each new module in a separate container – a portable software unit that includes all components of a given add-on, such as code, system tools, or system libraries – so that it can be executed anywhere.

You choose how to develop new modules

Regardless who does the development, we’ll provide you with all essential documentation and support staff. 


How we do it


Our dedicated PortaOne team develops and tests the code of your add-on


The code is immediately deployed to the cloud-based PortaOne Add-on Mart


Your on-premise PortaSwitch connects to the cloud-based container via API


We perform the final test, check everything again, and fine tune if necessary
