Synopsis

How it works

A filtered version of getinstances() that only returns InstancesInstanceThe base class for all Roblox objects (Parts, Models, Scripts, GUIs, etc.). Instances form a tree hierarchy (the DataModel). In Luau, they appear as userdata with shared metatables. whose Parent is nil. These are "orphaned" objects that exist in memory but aren't attached to the DataModelDataModelThe root Instance in Roblox's object hierarchy (game). Contains all services (Workspace, Players, ReplicatedStorage, etc.). Teleporting destroys the current DataModel and creates a new one. hierarchy. Games often create RemoteEvents, BindableEvents, and data tables parented to nil to hide them from normal traversal.

Discovery pattern

Common pattern for finding hidden RemoteEvents:

for _, inst in ipairs(getnilinstances()) do
  if inst:IsA("RemoteEvent") then
    print(inst.Name)
  end
end

Usage

Find nil-parented RemoteFunctions

for _, inst in ipairs(getnilinstances()) do
	if inst:IsA("RemoteFunction") then
		print(inst.Name)
	end
end

Returns

{Instance} Array of Instances with nil parent.
