ChunkPeek BETA

Which build do you need?

This mod ships a separate file for every mod loader and every version of the game. Pick both, then download — the wrong build installs fine and then does nothing in the game.

I don't know my version or loader

Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.

No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.

ChunkPeek

Stand in a chunk, see what's inside it.

The follow-up to LagPeek: once you know which chunk is the problem, stand in it and /chunkpeek tells you why. Read-only, no config.

What it shows

Chunk coordinates + block range
Entities in the chunk, grouped by type
Tile entities grouped by type — with hoppers called out specifically (the classic hidden lag source)
What's keeping the chunk loaded: players, /forceload, or a plugin chunk ticket (names the plugin!)
Inhabited time and whether it's a slime chunk

Install

Drop the jar in plugins/, restart. Nothing to configure. Requires Paper 1.21.x / 26.x (matching jar).

Command & permission

Command	Permission	Default
`/chunkpeek`	`chunkpeek.use`	OP

Player-only (it inspects the chunk you're standing in).

Safe by design

Read-only. The chunk you're in is already loaded, so nothing is ever force-loaded, and nothing is ever modified. Only network activity: one startup update check (Modrinth public API) + anonymous bStats stats.
