I’ve recently started using a kanban board which has been working well for me.
There are several options, I use obsidian for this because I can easily make a task into a note for further details.
Not FOSS of course but the .md file are easy to access and backup and i use the self hosted live-sync plugin to sync between 3 devices
I do exactly this with traefik.
ie: Seafile.domain.com
Vaultwarden.local.domain.com
