I used Kanboard for a year or so and still host an instance. But I haven't stuck with it. I just could never get other people to use it collaboratively, unfortunately in 2023 it's too ugly and doesn't pass the sniff test – especially on mobile.

I'm trying out Kanboard-like tracking on Obsidian, so far it's good. Doesn't have the same level of detail, but the superior mobile story makes it worth it for me.
