Valheim Lua EngineBuild Valheim gameplay in Lua

Synchronized resources, custom content, persistence, permissions, and runtime tooling for Valheim servers.

Resource runtime
Isolated client and server Lua VMs with lifecycle cleanup, synchronization, events, exports, and scheduling.
Server authority
Inventory, container, permission, persistence, and world APIs designed around server-owned decisions.
Custom content
Declare AssetBundles, network prefabs, items, recipes, and derived mobs directly from a resource manifest.
Operable by default
WebAdmin, profiling, health metrics, logs, resource controls, and JSON or MySQL-backed persistence.

Choose your path

Server owners: start with the server owner quick start for install, ensure, WebAdmin, permissions, updates, and day-to-day operation.
Lua developers: start with getting started, then move into resource structure and the Lua API.

  manifest.lua

lua

-- server.lua
RegisterCommand('hello_valheim', function(source)
  Player.Notify(source, 'Hello from Lua!', 'TopLeft')
end, false)

Add ensure my_resource to server.cfg, restart the resource, and the command is live. If you are operating a server, begin with the server owner quick start. If you are writing Lua, start with the installation and first-resource guide.
