Using Ninite Without the Website
We have an app version of Ninite called Ninite One that lets you pick the apps to install without visiting http://ninite.com. Ninite One is a free download for Ninite Pro subscribers.
It looks much more professional than pulling up the website in front of a client. Ninite One is also great for day-to-day general use since it's automatically tied to your Pro account and there's no need to log in to the site on each machine.
This page refers to pro-only features.
Subscribe to Ninite Pro to use them.
