I really liked tandoor but I moved to mealie cuz tandoor doesn’t have any method of backing up your instance and I lost all my recipes when switching to a new machine (a good part of that was user error too but the lack of a backup option to save my dumb ass meant I needed to look elsewhere)

Vikunja will cover all the bases you’re looking for I think! I’ve really been enjoying it
