A high-performance, ScriptableObject-powered inventory designed for developers who need a production-ready grid inventory that is easy to extend. Built for Unity 6 and 2022.3 LTS, it handles the complex logic of grid placement — multi-cell items, rotation, stacking, equipment, stash, shop, and save — so you can focus on your game.

Grid Inventory System ships with full source, sample scenes, and an editor that won't fight you on a Friday afternoon.
