Hi!
I want to self-host a Trello board for personal projects.
I came across several options and chose NextCloud Deck because it seemed the easiest to setup and run.
I customized the labels, used some custom CSS to color things more to my liking. Created the columns and started filling them up.
It get things done but I had some issues:
- The usability is nothing near Trello's
 - Image preview on cards do not work (image as covers works just fine)
 - No bulk editing
 - I haven't found a way to create cards in bulk
 - You can export and import decks via the Calendar App (WHY???)
 - You have to open a card to edit its tags
 - Tag customization is cumbersome
 
Now the pros:
- Fully integrated with NextCloud Apps and ecosystem.
 - Easy to add users and collaborate
 - Cards can have due dates
 - Cards can be assigned to users
 - Easy to move things around
 - Easy to install
 - Easy to use out of the box
 - some interesting 3rd party integrations (I didn't test)
 
I plan on testing LibreBoard later, but for now NextCloud Deck is good enough.
