🎒 Modular Inventory System for Godot 4

Stop rebuilding your inventory system from scratch.

Modular Inventory System is a reusable inventory framework for Godot 4, designed to give you the common systems most games need while remaining flexible enough to integrate into your own project.

Inventory management, equipment, hotbars, drag & drop, item data, serialization, tooltips, context actions, save/load and more are already included.

Spend less time rebuilding menus. Spend more time making your game.

Current version: 1.3.0
Tested with: Godot 4.7 Stable

🛠️ Built From Real Game Development Needs

This system grew out of the same problems I kept running into while making my own games.

Instead of rebuilding inventory, equipment, hotbars and item handling for every new prototype, I wanted a reusable foundation that I could expand and improve over time.

I'm continuing to develop the system as I use it in my own projects.
