Chest Peek is a fully client-side mod that lets you preview the contents of storage blocks without opening them. Aim your crosshair at a chest and a small slot-grid overlay pops up near your crosshair showing exactly what's inside — items, stack counts, and all — just like a tooltip. Look away, and it's gone.
### Features
- **World peek**: Aim at any block that holds items — chest, trapped chest, shulker box (any color), barrel, hopper, dispenser, dropper, furnace/blast furnace/smoker, brewing stand, crafter, and more — and its contents render as a clean bordered slot grid near your crosshair, without opening a screen. Works on the Ender Chest too, showing your own personal Ender inventory.
- **Shulker box tooltip preview**: Hover your mouse over a shulker box item in any inventory or container screen and its contents appear as the same slot grid, attached right to the item's tooltip — the same mechanism vanilla uses for Bundle previews.
- Empty containers still show the panel, clearly labeled so you know at a glance there's nothing to grab.
- No block is opened, no packets are sent to interact with it — this is a pure read-only, look-only preview.
### Requirements
- Minecraft 26.2
- Fabric Loader >= 0.19.3
- Fabric API 0.156.0+26.2
- Java 25
### Installation
Fully client-side — install it on your own client only. No server-side installation is needed, and it works fine on unmodified vanilla servers (or singleplayer).
### Known limitations
- Double chests are shown as two independent 27-slot halves rather than one merged 54-slot view.
