In the author's words

Fabric mod for Minecraft that automatically merges dropped item entities on the ground into stacked entities — reducing item lag on servers and singleplayer worlds. Configurable stack size, scan radius, and scan interval.

Scan

Scanned on 4 November 2026 against Kiln 0.2.0, file drop-stacker-1.3.0.jar. The scan reads the mod's classes; it does not run them.
