What I'm looking for, ideally, is a FOSS solution which gives a docker image, that I can just point my website to and boom- Free public roadmap/feature upvote stack. (like one of those status page thingies but for roadmap)

The solution should let users sign up, add feature requests, upvote other requests, comment on them etc. Bonus point for letting the dev add different tags or put it in a kanban board (done, in progress, backlog etc.) - All of it with a public frontend.

Anything like this out there?
