Is there a place that I can find community batch connect & passenger apps?

besides the Github search bar, I tried that already…

In the docs we have a section that links to other interactive apps that institutions have shared with us:

As for passenger apps, I’m not aware of a page that we maintain for external community passenger apps. In fact, the Passenger App section of the docs is currently being restructured and having content added in order to provide a better idea of what can be done with the passenger apps, such as hosting a science gateway. I can give you an update when those are done, which should be in the next few weeks.
