On: Pivotal Tracker will shut down

Noooo I use tracker for everything. There's no project management software like it in simplicity and function. You'll be missed

I do like the approach Basecamp took to Kanban ("Card Table") - very very simple and clean (https://basecamp.com/features/card-table). We moved off of Basecamp but we found it super effective when we were a smaller team.

You should try out Taiga.io. Super simple (possibly TOO simple), light-weight, open-source and self-hostable.
