Single admin dashboard for all apps or app+admin for each?

I have several web apps that almost equal to each other in terms of code and db schema. If not completely equal. The content of an app/html pages, db and design/css are different.

I want to create simple admin dashboard for them. Will it be better to create a single admin dashboard for all of them? Where I could select an app to administrate. Or create admin dashboard for each one at “”?

Both solutions have advantages and disadvantages. I’d go with the “single admin dashboard” solution, but there’ll be an issue: I’ll have to deal with multiple db connections in particular to each app: initialize it, close it, keep credentials, declare RepoAppN, for instance.

What do you recommend?
