# Chest Peek 1.6.2 Look at a container and see what is inside it. No opening, no commands. Fabric · Minecraft 1.21.9+ · Requires Fabric API · Works as a client mod, does more when installed on the server too --- ## Highlights - **Live contents on servers.** Put the same jar on your server and containers show their contents without anyone opening them, including chests other players have filled. Players without the mod are unaffected. - **Automatic indexing.** In singleplayer, containers around you are recorded every ten seconds and on world load, so chests are already known before you walk up to them. - **Item filter.** Keep a list of things you care about and hide everything else from both the overlay and the search. - **A steadier panel.** The overlay keeps one width per container, so hiding empty slots or switching filters no longer makes it shift or jump. --- ## Overlay - Works on chests, barrels, shulker boxes, hoppers, droppers, dispensers, furnaces, blast furnaces, smokers, brewing stands, chiseled bookshelves and ender chests. - Contents are drawn in the container's real slot order. Double chests read as one 54 slot container from either half. - The header shows the container name, slots used, free slots, and when the contents were last recorded. - The panel lifts itself above the hotbar, health and armour rows instead of drawing over them. - A quiet tick plays when the overlay opens on a container you were not already looking at. ## Server support (optional) - The same jar doubles as a server mod. Nothing is required of players who do not have it. - Clients detect server support on their own and fall back cleanly when it is absent. - The server only answers for containers within **64 blocks** of the asking player, in loaded chunks. - Requests are rate limited per player: **20** single lookups per second, **1** area scan every 4 seconds, scans capped at **48 blocks** and **256 containers**. > On a plain vanilla server the client is never sent container contents, so a chest becomes known the first time you open it and stays known from then on. ## Saved chests - Every container you see is saved permanently to `config/chestpeek-chests.json`, split per world and per server. - Ender chest contents resolve from any ender chest block once recorded. - Containers that no longer exist are dropped from the record once you are near enough to confirm it. ## Search - Search everything you have seen by item name. Results show counts, distance and coordinates, nearest first. - Items packed inside shulker boxes are searchable, and results say which box they are in. - The header totals a matched item across every result, for example `1284x Iron Ingot across 12 chests`. - Open any result for its full contents grid, with hover details listing what is inside a shulker box. ## Per chest - Give a container a name. The name replaces the block name in the overlay and is searchable. - Copy a counted contents list to the clipboard. - Forget a single container. ## Filter - Add item or block names, or parts of names such as `iron` or `log`. - Up to 24 entries, toggled on and off without clearing the list. - Matching stacks keep their slot positions; everything else is blanked out. ## Settings Every option explains itself on hover. | Setting | What it does | | --- | --- | | Peek | Always, hold a key, or off | | Peek range | Up to 32 blocks | | Empty slots | Shown or hidden | | Item filter | Opens the filter list | | Hover sound | On or off | | Search radius | Up to 128 blocks | | Index chests automatically | Singleplayer background indexing | | Panel size and position | Drag a live preview, snap to grid, scale 0.5x to 2.0x | | Delete all saved chests | Clears the record for the current world | ## Keys | Key | Action | | --- | --- | | `V` | Toggle the overlay | | `N` | Open Chest Peek | | `B` | Open the container you are looking at | | unbound | Hold to peek | All rebindable under **Options → Controls → Chest Peek**. ## Performance - Live reads are throttled and skipped entirely when a container's contents have not changed. - Saving runs off the render thread. - The overlay caches its layout between frames and rebuilds only when something actually changes. - Search results compute their matches once per query rather than once per frame. --- ### Upgrading If you had dragged the overlay to a custom position, it is anchored by its centre now rather than its left edge, so it will sit half a panel to the left once. Drag it back and it will stay put.
