Im currently working on a auto duper addon for both Dupe Anarchy and Duck Anarchy,
For Dupe Anarchy there is modules such as auto crystal dupe, anchor dupe, pearl dupe, totem dupe. The Code Runs the command /dupe {amount}{item} once the player has less than the selected threshold.
For Duck Anarchy it includes Chest Dupe And Item Frame Which can automaticly dupe selected items using either chest dupe or item frame dupe.
