OpenKeep
Craft from chests, quick stack, sort, trash, salvage, stack sizes, chest sizes, carts as workbenches, contents signs. Open source, server synced.OpenKeep
Storage and inventory for Valheim in one mod: craft, build and feed stations straight from nearby chests, ship holds and carts; stow, top up, sort, junk and route from the inventory panel; a Salvage tab that gives materials back; stack sizes and weights; bigger chests with their contents on hover; carts that carry a workbench; and a sign above every chest that names what is inside. Every gameplay setting is server synced and lockable, every hotkey is per player, and everything is tunable in the config file and six YAML files that hot reload. Convenience features are on by default; anything that changes balance (stack sizes, weights, chest sizes) defaults to vanilla.
Reach: craft from storage
- Wherever the game counts what you carry (crafting rows, the craft and upgrade buttons, the hammer's piece list and requirement rows, station hover texts) it now counts your inventory plus every reachable container.
- Paying takes from the inventory first, then from containers nearest first. The requirement rows show
3 + 12(inventory plus storage, storage in its own colour), or the total, or the vanilla number (Requirement Display), and flash once after a pull. - Stations: use a smelter, kiln, blast furnace, spinning wheel, windmill, campfire, torch, hot tub, cooking
station, oven or fermenter with nothing to add in your inventory and one unit comes from the nearest container.
Hold
Fill Modifier(Shift) to fill it up, holdPull Modifier(Alt) to move a stack into your inventory instead. Hover texts get aFrom storage: nline. Thestations:map inOpenKeep.Reach.ymlnarrows this per station prefab:denykeeps items out of the feeding (raw meat you want to keep raw, say),allowlimits it to a list,enabled: falseleaves a station entirely alone — crafting and building are untouched. - A reachable container has the game's
Containercomponent and is withinRange(20 m by default), passes the game's own privacy and ward checks, and is not open by another player (see "Shared chests"). Detection is by component, never by a name list: any object with a container is a container, it is a ship when it carries the game's ship component and a cart when it carries the cart component. Vanilla ships (Karve, Longship, Drakkar), modded ships and modded chests are all found the same way. Standing on a moored ship you craft, build and feed stations from its hold; the ship and cart switches are in section0. Containers. Toggle Key(Alt + R) switches the whole module off for your character;Link Key(Alt + L) draws lines from every container in range to the stations it serves, and placing a chest draws them too.
Stow: stow, top up, sort, junk, route
A row of buttons just below the player panel (Quick stack, Store all, Top up, Sort), a trash can on its
own wood plate between the armour and weight readouts on the panel's right (those two show a larger icon behind
their number and stay put when the inventory grows), and a Sort button below the open container's panel, under
its Take all line; Button Row Offset moves the rows up or down if your screen layout needs it. Every action also has a hotkey that works while the inventory is open. The module is
one workflow for coming home with a full inventory. Open a chest and stow: quick stack (Q) moves every stack
whose item the open container (or, with Quick Stack Nearby, any container within Nearby Range) already holds,
and Store all (G) moves everything that may move into the open container; neither touches your hotbar. Then top up (R): every stack you
carry that is not full is refilled from the chests, so you leave with what you came with. Sort (T for the
inventory, Y for the container) orders by Category, Name, Weight or Value; the hotbar, favourite slots
and equipped items stay put and stacks merge; with Sort Favourite Items off, favourite items stay put too —
turn it off when another mod keeps items in extra slots the sort would pull out, and favourite those items. Quick
stack, store all, dump and sort work only on the rows the game gives you (four, more once you buy them from the
trader). Mods that add equipment, food or ammo slots keep them in rows below those, so these actions leave the
slots alone, and top up still refills the food and ammo there. If a mod adds ordinary inventory rows you want
stowed and sorted too, set Main Inventory Rows to the number of rows to use. What you never want to keep is junk: mark an item with J, and
Destroy Junk (Shift + Delete) destroys every junk stack in one go; Trash Key (Delete) destroys the hovered
stack and the trash can takes a dragged one, at once (turn on Confirm Trash for the game's popup first). What does not belong in
the open chest is routed: Ctrl + click sends a stack to the nearest container that holds the item, an item of its
group, or accepts it in OpenKeep.Stow.yml; Store one (V) sends a single item; Find (Z) marks every nearby
container holding the hovered item with a line and a count; Dump (Alt + D) quick stacks to every nearby container
without opening the inventory; the left and right arrows or the mouse wheel over the container grid cycle
through the chests around you.
- Favourite item (
F): the item is never quick stacked, stowed, dumped, trashed or salvaged. Favourite slot (Shift + F): the slot's content never moves. Top up still refills favourites. - Ground pickup (off by default): containers whose prefab has
pickup: truein the YAML pull dropped items from the ground afterPickup Delayseconds, only items they already hold unless the YAML says otherwise.
Favourites and junk marks are saved with the character and follow it between worlds.
Salvage
A third tab, Salvage, after Craft and Upgrade. It lists every stack in your inventory that has a recipe; select
one and the requirement rows show what comes back, the craft button reads Salvage. Returns are Return Fraction (0.75) of each material, rounded, at least one, upgrade materials included; never more than the item
cost. Trophies, quest items, favourites and items on the deny list of OpenKeep.Salvage.yml are not listed. Nor are
items carrying another mod's item data (Skip Items With Mod Data, on; Mod Data Prefixes, default ecf_), so
salvaging never destroys affixes or other state a mod keeps on the item. Salvage Key (Backspace) salvages the
hovered stack after confirmation. If the materials do not fit, nothing happens.
With EliteCrafting installed: OpenKeep salvages ordinary crafted items into materials and leaves EliteCrafting's magic items alone; those are ground into shards by EliteCrafting's own Salvage key.
Stacks: stack sizes and weights
Stack Multiplier and Weight Multiplier (both 1 by default) scale every item; OpenKeep.Stacks.yml sets
absolute values per item, pattern or group. Values show in tooltips before an item is ever moved. Ignore Teleport Restriction lets everything through portals. Merge Into Chests fills a chest's partial stacks when
you drag a stack in. Per Item Config Entries generates one stack and one weight entry per item into the config
file for Configuration Manager users. Write Documentation writes OpenKeep.Items.txt (every item, prefab name,
vanilla and current values) and OpenKeep.Containers.txt (every container prefab and its size) next to the cfg.
Capacity: container sizes and hover contents
OpenKeep.Containers.yml is filled with every container prefab of your game (modded ones included) and its
vanilla size the first time a world loads, all commented out; uncomment a line and change the numbers to resize
new and existing containers of that prefab. Hovering a container shows how full it is and up to Hover Lines
lines of contents.
Carts as workbenches
Cart Workbench (off by default) gives every cart a workbench: craft (Shift + E on the cart), repair and build
within Cart Station Range as if a workbench stood there, no roof needed. Cart Station Level sets its level;
workbench extensions near the cart add to it.
Signs: what is in the chest, without opening it
Off by default (7. Signs / Enabled). When on, every container a player has built gets a real vanilla sign
floating just above it, facing the same way, that lists the contents most numerous first: Wood, Stone, Resin, Flint, or Wood 120, Stone 45 with Show Counts. The sign is rewritten within Update Seconds (2) of any
change by whoever owns the chest at the time, lists at most Max Items (4) kinds, never exceeds Max Characters
(50) and ends with an ellipsis when something was left out; an empty chest shows Empty Text (blank by default).
Height (0.1 m above the chest's top) and Rotation (degrees added to the chest's facing) move every sign;
OpenKeep.Signs.yml switches prefabs off and moves or turns the sign per prefab.
- Your own words win: edit a sign with
Eand the mod leaves it alone until you clear the text. - Removing a sign with the hammer means "no sign here": the chest gets none again, even after a reload, until
openkeep signs reset. A sign a troll smashes simply comes back. Automatic signs never crumble or rot: they need no support and no roof (player-placed signs are unchanged). - Removing the chest removes its sign. Ship holds, carts, dungeon chests and spawned treasure get no sign; the private chest gets one.
- The sign costs nothing, but it is the vanilla sign: removing it with the hammer returns one wood, so a removed
sign is a wood each. The signs are ordinary pieces of the world: every player sees them, they are saved with the
world, and they stay in the world when the mod is removed (they just stop updating). Switch
Enabledoff before removing the mod if you want them gone; the chest owners' games take every sign down as the chests load.
Shared chests: several players in one chest
The game gives a chest to the player who opened it and refuses everyone else while it is in use. Shared Chests
in section 0. Containers (default Off) changes that:
Off: as the game: a chest someone else has open is skipped by every OpenKeep action and refused when you interact with it.View: interacting with a chest another player has open shows its contents read-only, titledChest (in use by <player>), refreshed as they change; when the other player closes it your panel turns live without closing.Full: asView, and two people can work the same chest at once. Click, drag and drop, the split dialog, Take all and Stack all send a request to the chest owner's game, which applies it or refuses it; nothing is moved on your side until it says yes, so if both of you grab the same stack exactly one gets it and the other seesSomeone else got there first. A slot the other player pressed the mouse on is tinted (Touch Colour) and its tooltip says<name> is moving this. A request without an answer afterRequest Timeout(2 s) counts as refused:The chest did not answer.
OpenKeep's own quick stack, store all, top up, routing, store one, dump and trash work into a shared chest the
same way; the message for such a chest arrives when its answer does (Moved n stacks to Chest). Sorting a
chest someone else is using is refused. Crafting, building and station feeding never count or pay from a chest
another player is using, whatever the mode, so a requirement is never shown as covered by an item the other
player may take first. Both players need the mod; a player without it gets the game's usual refusal.

Config file
BepInEx/config/milkyteam.openkeep.cfg, written on first start. Sections: 0. Containers (Ships, Carts,
Player Chests, Honour Wards, Shared Chests), 1. Reach, 2. Stow, 3. Salvage, 4. Stacks (plus 4a. Item Stacks and 4b. Item Weights when per item entries are on), 5. Capacity, 6. Carts, 7. Signs (Enabled,
Show Counts, Max Items, Max Characters, Update Seconds, Height, Rotation, Empty Text), 9. Shared
(Request Timeout, Touch Seconds; per player Show Touches, Touch Colour), and General / Lock Configuration.
Every entry has a description in the file. Gameplay settings are synced from the server and locked; keys,
display formats, confirmations, sort orders and colours are yours.
YAML files
Next to the cfg, created on first start, hot reloaded a few seconds after a save, synced from the server, and
editable in game through the Configuration Manager entries Edit YAML. Extra files named
OpenKeep.<Module><anything>.yml are merged in. Every list uses the same vocabulary: Wood (prefab name or
$item_wood), prefix:Trophy, suffix:Ore, type:Material, group:Ores (a group of the file's groups: map),
* (everything). Container keys are prefab names; OpenKeep.Containers.txt lists them all.
OpenKeep.Reach.yml: which containers Reach may use, per prefab range and item lists, and what each station
prefab may be fed (feeding, Fill, Pull and the hover line only; crafting and building are untouched).
# range: 20
groups:
Ores: [prefix:CopperOre, TinOre, IronScrap, SilverOre, BlackMetalScrap, FlametalOre]
containers:
piece_chest_private:
enabled: false
Cart:
range: 10
VikingShip:
deny: [type:Trophy]
piece_chest_blackmetal:
allow: [group:Ores, type:Material]
stations:
piece_cookingstation:
deny: [NeckTail] # never pulled onto the cooking station; crafting still sees it
smelter:
allow: [group:Ores]
charcoal_kiln:
enabled: false # no feeding, filling, pulling or hover line for this station
Ground pickup is off unless Ground Pickup is on in the config and the chest prefab has pickup: true in the YAML; it is a world tick that runs on the chest owner's client, so turn it on deliberately.
OpenKeep.Stow.yml: groups for routing and the ground pickup rules.
groups:
Ores: [prefix:CopperOre, TinOre, IronScrap, SilverOre, BlackMetalScrap, FlametalOre]
containers:
piece_chest_blackmetal:
pickup: true # takes items from the ground (needs the cfg Ground Pickup switch)
accept: [group:Ores] # taken and routed here even when the chest does not hold them yet
refuse: [type:Trophy] # never taken, never routed here
OpenKeep.Salvage.yml: what is never salvaged and per item fractions.
deny: [type:Trophy, prefix:MeadBase]
overrides:
ArrowFlint: { fraction: 0.5 }
OpenKeep.Stacks.yml: absolute stack sizes and weights; the multipliers here replace the cfg ones.
stack multiplier: 2
items:
Wood: { stack: 100 }
Stone: { stack: 100, weight: 1.0 }
group:Ores: { weight: 5 }
OpenKeep.Containers.yml: container grid sizes.
containers:
piece_chest_wood: { width: 8, height: 4 }
VikingShip: { width: 8, height: 3 }
OpenKeep.Signs.yml: which containers get a contents sign and where it sits. offset moves the sign from the
computed place (the middle of the container's top, Height metres up) in the container's own axes, x right, y up,
z forward, in metres; rotation is added to the container's facing on top of the Rotation setting.
containers:
piece_chest_wood: { enabled: true, offset: [0, 0, 0.3], rotation: 0 }
piece_chest_private: { enabled: false }
Server settings
Gameplay settings come from the server. With Lock Configuration on (the default), every player uses the server's
values and cannot change them locally; server admins can still edit them in game. With it off, each player uses
their own file. In the console (F5), charter status shows whether the server binds your settings, charter diff
lists where the server's values differ from your own file, and charter versions lists the mods on both sides.
Joining with a missing or mismatched version of the mod shows one screen naming the mod and both versions, with a
refusal code that is also written to the server's and your own log.
Console command
openkeep reload reloads the cfg and every YAML file (admin or host on a server). openkeep containers lists the
reachable containers around you with prefab name, distance and item count. openkeep write docs writes
OpenKeep.Items.txt and OpenKeep.Containers.txt. openkeep signs lists the loaded containers with their sign
state (sign, player text, no sign, opted out); openkeep signs reset (admin or host on a server) allows signs
again on containers whose sign was removed with the hammer; openkeep signs rewrite rewrites the sign of every
loaded container your game owns.
Install
- Install BepInEx for Valheim.
- Install this mod. On a server, install it on the server and on every client.
For manual install, drop OpenKeep.dll into BepInEx/plugins. The config file and the YAML files are created on
the first run. A server pushes its gameplay settings and YAML files to every client; with Lock Configuration on
(the default) clients cannot change them while connected.
Warnings
- Items in the extra rows and columns of an enlarged container are invisible to players without the mod and to the vanilla game. Everyone on a server should run the same container sizes.
- Lowering a stack multiplier or an absolute stack size, or removing the mod, loses the part of a stack above the new maximum when the inventory that holds it loads. Split large stacks before lowering a limit.
- Signs are real vanilla signs. They stay in the world when the mod is removed, and each one removed with the
hammer returns one wood. Switch
7. Signs / Enabledoff before removing the mod to have them taken down.
