Drop Stacker

A Fabric mod for Minecraft that automatically stacks dropped item entities on the ground into a single entity, reducing entity lag and keeping your world tidy.

Features

• Dropped items of the same type and NBT automatically merge within a configurable radius
• Stacks beyond vanilla's 64-item limit — up to your configured maxStackSize
• Colorful stack count label displayed above items:
  • 🟢 Green — 64 or below
  • 🟡 Yellow — 65 to 500
  • 🔴 Red — above 500
• Optional despawn countdown timer on the label:
  • 🟢 Green — plenty of time remaining
  • 🟡 Yellow — under 2 minutes
  • 🔴 Red — under 30 seconds
• Server-side merge logic only, no client-side desync
• New config fields are added automatically on server restart — no manual editing needed

Requirements

• Minecraft 26.1.2
• Fabric Loader 0.19.1+
• Fabric API
• Fabric Language Kotlin
• Java 25+
