Overstacked: The Essential Inventory Mod for Hytale

Overstacked is one of the most downloaded mods in all of Hytale, with over 237,000 downloads on CurseForge in just weeks after launch. Created by DarkhaxDev - a prolific modder with over 1.9 billion total downloads across multiple games - it targets one of the most common complaints in early-access Hytale: inventory management is a constant chore.

What Does Overstacked Do?

Hytale's default stack sizes for common resources are low. If you have spent any time mining stone, chopping wood, or farming materials, you already know the feeling: your inventory fills up fast, and you end up making multiple trips back to your storage just to keep working. Overstacked fixes this by increasing the maximum stack size of the most frequently gathered items in the game, letting you carry significantly more before needing to head home.

Beyond the preset changes, the mod includes a fully configurable JSON system, so you can customize every single item stack size in the game to your liking.

Default Stack Size Changes

Out of the box, Overstacked applies the following increases:

Ore stacks doubling from 25 to 50 is particularly noticeable during mining runs. The change to wood, rocks, and soils means that a full build session requires far fewer storage trips.

How to Configure Overstacked

This is where the mod genuinely stands out. On first launch after installing, Overstacked generates a Darkhax_Overstacked folder inside your mods directory. Inside it is a MaxStackSizes.json file you can open and edit with any text editor, including Notepad.

The config works in two ways:

ItemIds - direct item mapping

Assign a specific stack size to any item using its exact ID:

{
  "ItemIds": {
    "Rock_Stone": 999,
    "Soil_Dirt": 5
  }
}

You can set any value from 1 upward. To leave an item unaffected, simply remove it from the list. There is no limit to how many items you can configure this way.

Patterns - regex matching

For bulk changes, the Patterns section lets you write a regex expression that applies a stack size to every matching item ID at once. For example, the pattern ^Furniture_.*_Stool$ applies a new stack size to every stool item in the game in a single line. This is especially useful for modded environments where new items are regularly added.

{
  "Patterns": {
    "^Furniture_.*_Stool$": 200
  }
}

Regex patterns are powerful but require care - a broad pattern could unintentionally match items you did not plan to change, so always test your changes in a non-critical world first.

How to Install Overstacked

For a solo world:

1. Launch Hytale and go to the Worlds tab.
2. Right-click your world and select Open folder.
3. Open the mods subfolder and drop the Overstacked .jar file inside.
4. Restart the game - the mod is now active for that world.

For a server:

1. Download the .jar file from CurseForge and ensure the mod version matches your server version (currently Early Access builds).
2. Drop the file into your server's mods folder.
3. Restart the server. The Darkhax_Overstacked config folder will generate automatically on first boot.

No dependencies are required. The mod works standalone.

Is Overstacked Balanced?

That depends on your definition of balance. Doubling ore stack sizes from 25 to 50 is a mild convenience change. Pushing wood and stone to 250 or beyond is a much larger shift - you can now carry the materials for a full building session in one inventory, which removes a significant time sink from the early game.

The mod is entirely opt-in and configurable. If you only want the ore change and nothing else, the config makes that trivial. For server administrators, this is actually one of Overstacked's biggest selling points: you can define exactly how permissive the stack sizes are for your player base.

Why It's One of Hytale's Most Downloaded Mods

Hytale's inventory pain is a recurring topic in the community - the default stack sizes feel like a holdover that was never calibrated for how resource-intensive the game's building and crafting systems actually are. Overstacked is the cleanest available fix: lightweight, no dependencies, immediate results, and infinitely customizable.

For any player doing sustained resource gathering, building, or server play, Overstacked is close to a must-install. It does not add new content or change how the game plays - it removes friction, and sometimes that is exactly what a mod needs to do.
