I think everybody on here is constantly keeping an eye out for what to host next. Sometimes you spinup something which chugs along nicely but sometimes you find out you’ve been missing out.
For me it’s not very refreshing or new: Paperless-ngx. Never thought I would add all my administration to it. But it’s great. I probably can’t find the thing I need, but I should have a record of every mail or letter I’ve gotten. Close second is Wanderer. But I would like to have a little bit more features like adding recorded routes to view speed and compare with previous walks. But that’s not what it is intended for.
What is that service for you?
So paperless works as a service that ties into your storage. I point mine at an NFS share on my Synology and just backup that share. The documents are all stored as PDFs still so worst case I still have “dumb” copies without all the tagging available if my paperless instance goes offline for some reason.
