ShulkerPeek — Horizon mod

See inside shulker boxes without placing them: all 27 slots as a 9 x 3 grid in the tooltip, with icons and stack counts.

Shulker boxes are endgame storage, and the annoying part is that you can't see inside without placing one. ShulkerPeek by vstxx fixes that: hover a box and its 27 slots appear in the tooltip as a 9 x 3 grid, laid out like the box's own screen, with item icons and stack counts. It's for anyone who sorts loot into colour-coded boxes, comes back from the End with a full inventory, or trades boxes with friends.

Features

Plain and all 16 dyed shulker boxes, whether empty, partly filled or full.
Works on every screen with item tooltips: inventory, chests and other containers, creative inventory, the item panel, chat item links and trading.
The usual tooltip lines stay; the grid sits underneath.
Respects hidden tooltips (minecraft:tooltip_display).
Uses your resource pack's own shulker box texture.
Settings: always or Shift-only, a grid for empty boxes, dye-colour tint.

Compatibility and install

Native mod, version 0.1.0, for Minecraft 26.3, built for Horizon Nightly 2026-10-29 (5e391eb). It builds alongside Horizon's official native mods. Install it from the launcher's Mods page and press Build; the first native build downloads Rust and takes 20–30 minutes, later ones a few minutes.

Limitations

The grid works in single player, LAN worlds you host and on vanilla servers. On other Horizon servers that don't run the mod, boxes look empty — a quirk of Horizon's built-in server, not of ShulkerPeek itself.

FAQ

Why do shulker boxes look empty on some servers?

Horizon's built-in server currently leaves box contents out of what it sends to the game window. ShulkerPeek sends them the way vanilla does, so the grid works in single player, LAN worlds you host and vanilla servers, but boxes look empty on Horizon servers without the mod.

Can I show the grid only when holding Shift?

Yes. In Options > Mods > ShulkerPeek > Settings choose always or Shift-only; you can also show a grid for empty boxes and tint it with the box's dye colour.

Can it mess up my world?

The author says it never changes items, inventories or worlds, and you can turn it off at any time in Options > Mods.

How do I install ShulkerPeek?

From the Horizon launcher: Mods page → find "ShulkerPeek" → Install. The launcher checks the SHA-256 for you. A native mod is then compiled with the Build button — the first build takes 20–30 minutes. The full steps are in "How to install" above.

Which Minecraft version does ShulkerPeek support?

The latest version, 0.1.0, targets Minecraft 26.3 on Horizon. Heads up: it currently doesn't build on the newest nightly — see the compatibility note.

Can I download ShulkerPeek from this site?

Yes. Its MIT license allows redistribution, so we host the file, and its SHA-256 matches the official registry.
