I used it with Wekan for project management and I also run Dokuwiki for self-hosted docs. It has been zero maintenance for me so it has been great.
However, the packages ecosystem seems unmaintained. It is a pitty because I think the tool has a ton of potential and I really liked it.
I am considering moving to Yunohost or something similar but right now my little server hosts, together with other services, Sandstorm and I think Yunohost needs to monopolize the server.
So I would ask for recommendations on similar tools. Not bare Docker containers but fully lanaged platforms wirh one click installs where it is easy to add/remove users.
