Item Flow Monitor

Real-time item throughput monitoring for Minecraft containers

Open any container, enable tracking, and see the item flow rate in real time.

---

Item Flow Monitor adds an unobtrusive UI overlay to standard Minecraft containers that shows the rate of items flowing through them. Perfect for players who build farms and want to measure throughput without manual counting.

This mod does not add any new blocks or items. It only adds an informational overlay to existing container screens.

Features

• Real-time flow rate — see items/min or items/hour directly in the container UI
• Time-to-full estimate — hover over the rate to see when the container will be full
• Three calculation modes — Average (stable long-term), Actual (exact count per window), Predicted (real-time EMA estimate)
• All standard containers — chests, double chests, hoppers, furnaces, blast furnaces, smokers, barrels, dispensers, droppers, shulker boxes
• Flexible item tracking — track all items, auto-detect the first item, or manually select a specific one
• Configurable via Mod Menu — toggle tracking per container type
• 12 languages — English, Russian, Chinese, Spanish, German, French, Japanese, Korean, Portuguese, Italian, Polish, Ukrainian
• Lightweight — observer-based architecture, zero overhead without active trackers
