Dupers Server

DupersPlugin is a lightweight but powerful duplication plugin designed for PaperMC servers. It provides controlled item duplication with a rank system, configurable cooldowns, and built-in protections to prevent abuse.

Players start with the default Duper rank, while higher-level duplication features are reserved for players with the Duper+ rank. Server operators can grant this rank using a command.

The plugin includes advanced safety systems such as recursive container scanning, which prevents players from duplicating banned items even if they are hidden inside nested containers like bundles or shulker boxes.

Inventory handling is fully managed to respect stack limits, automatically distribute items into available slots, and prevent overflow issues.

Cooldowns are applied per player and displayed using an action bar, ensuring clear feedback and preventing spam usage.

Chat formatting and overhead tags visually distinguish between Duper and Duper+ players.
