Tired of your inventory filling up after 5 minutes of mining?

Inventory screen showing stacks of 1,000 items

OverStack is a revolutionary Bedrock Edition add-on that shatters the vanilla stack limit! Using advanced Scripting APIs, this add-on allows you to compress items into massive virtual stacks—up to 1,000 items per slot—keeping your inventory clean and organized.

✨ Key Features

  • Break the 64 Limit: Store up to 1,000 items in a single inventory slot.
  • The Stack Regulator: A specialized tool that manages your compression system.
  • Progression System: Upgrade your stack limits using XP and Chests.
  • Auto-Stacking: Items automatically compress as you pick them up.
  • Safety Mode: Easily pause the system to craft or trade without issues.
  • Visual Indicators: Items show their real count in the name tag (e.g., Deepslate (x1000)).

🛠️ How It Works

Inventory compression menu with max stack reached

1. The Stack Regulator

When you load the world, the Stack Regulator item will appear in your inventory automatically (or check the Creative inventory). This item is your control panel.

  • Right-Click (Use) the Regulator to open the Upgrade Menu.
  • Sneak + Right-Click the Regulator to Pause/Resume the mod.

    • Tip: Always PAUSE the mod before crafting with high-stack items!

2. Upgrade Tiers

You start with a limit of 64. To hold more, you must upgrade your Regulator using Experience Levels and Chests.

Tier Level Stack Limit Cost to Upgrade
Tier 1 64 Items (Default)
Tier 2 128 Items 5 XP + 2 Chests
Tier 3 256 Items 10 XP + 4 Chests
Tier 4 512 Items 15 XP + 8 Chests
Tier 5 1,000 Items 20 XP + 16 Chests

3. Unpacking Items

Need to use your items?

  • Sneak + Right Click while holding a stacked item to unpack it back into vanilla stacks.
  • Placing blocks works normally! The system handles the count automatically.

⚙️ Technical Info & Installation

  • Supported Version: Minecraft Bedrock 1.21.120+
  • Requirements: You must enable Beta APIs in your world settings for the scripts to function correctly.
  • Compatibility: This add-on uses the Script API. It is generally compatible with other addons, but items with custom durability or enchantments will not be stacked to prevent data loss.
