If you are already selfhosting Gitea, it has a nice kanban-style project board view that works similarly. This is what I use, and find it to be pretty good. It’s not as good as a dedicated solution but it’s one less app I have to tend to, and the Gitea backups are already mega mission critical so the PM stuff (and issues and wikis) get this vigilance baked in for free.
