A plugin is an extension that adds additional features or functionality to Studio. You can either find, install, and manage community-made plugins from the Creator Marketplace, or you can create and publish your own to the Toolbox to use across your experiences. If you choose to also publish your plugins to the Creator Marketplace for creators to use within their own development processes, you can either offer them for free or sell them for Robux.

Creating New Plugins

You can create your own plugins to improve your workflow in Studio. The following code sample is a plugin called EmptyScriptAdder that inserts an empty script as the child of an object or in ServerScriptService. The following sections explain the major parts to creating this plugin.

EmptyScriptAdder Plugin

local ChangeHistoryService = game:GetService("ChangeHistoryService")
local Selection = game:GetService("Selection")
-- Create a new toolbar section titled "Custom Script Tools"
local toolbar = plugin:CreateToolbar("Custom Script Tools")
-- Add a toolbar button named "Create Empty Script"
local newScriptButton = toolbar:CreateButton("Create Empty Script", "Create an empty script", "rbxassetid://4458901886")
-- Make button clickable even if 3D viewport is hidden
newScriptButton.ClickableWhenViewportHidden = true
local function onNewScriptButtonClicked()
local selectedObjects = Selection:Get()
local parent = game:GetService("ServerScriptService")
if #selectedObjects > 0 then
parent = selectedObjects[1]
local newScript ="Script")
newScript.Source = ""
newScript.Parent = parent
ChangeHistoryService:SetWaypoint("Added new empty script")

Saving a Plugin Script

Plugins start from scripts. To create a plugin, create a Script and save it as a plugin using the Explorer. For example, to create the EmptyScriptAdder Plugin:

  1. Insert a new Script inside ServerStorage and rename it to EmptyScriptAdder.

  2. Copy and paste the EmptyScriptAdder Plugin code into the new script.

  3. Right-click the script in the Explorer and select Save as Local Plugin.

  4. In the popup window, click Save to insert the plugin script into your local Plugins folder of the Studio installation. The Output window indicates that the plugin successfully saved and the plugin runs for the first time after you save it.

Adding a Toolbar Button

To add a button for your plugin to the Plugins tab of the Studio toolbar, use the Plugin:CreateToolbar() and PluginToolbar:CreateButton() methods. In the code for EmptyScriptAdder, line 5 creates a new section in the toolbar named Custom Script Tools and line 8 creates a button named Create Empty Script.

Executing Code on Click

To make the plugin execute code when a user clicks the toolbar button, connect a function to the button's PluginToolbarButton.Click event. In the code for EmptyScriptAdder, the connecting function is onNewScriptButtonClicked.

Checking User Selection

To modify a plugin's behavior based on what the user has selected, use the Selection service. The onNewScriptButtonClicked function checks if the user has anything selected and creates the new script as its child instead of inside ServerScriptService. If the user doesn't have anything selected, it creates the new script in ServerScriptService.

Supporting Undo and Redo

Use ChangeHistoryService to allow users to undo and redo changes made by a plugin within an experience. In your script, set the plugin to call ChangeHistoryService:TryBeginRecording() and store the identifier assigned to the API call before making changes. Then set the plugin to call ChangeHistoryService:FinishRecording() after making changes, so it captures any changes made during the recording session for undo and redo.

The following code sample creates an example plugin that can apply the neon material to selected parts. It uses ChangeHistoryService to record and manage the changes made by the plugin:

Example Material Plugin with Recordings for Undo and Redo

local ChangeHistoryService = game:GetService("ChangeHistoryService")
local Selection = game:GetService("Selection")
-- Create an example plugin
local toolbar = plugin:CreateToolbar("Example Plugin")
local button = toolbar:CreateButton("Neon it up", "", "")
-- Connect a function to the click event
local parts = {}
for _, part in pairs(Selection:Get()) do
if part:IsA("BasePart") then
parts[#parts + 1] = part
if #parts < 1 then
-- Nothing to do.
-- Try to begin a recording with a specific identifier
local recording = ChangeHistoryService:TryBeginRecording("Set selection to neon")
-- Check if recording was successfully initiated
if not recording then
-- Handle error here. This indicates that your plugin began a previous
-- recording and never completed it. You may only have one recording
-- per plugin active at a time.
-- Iterate through the selected parts
for _, part in pairs(parts) do
part.Material = Enum.Material.Neon -- Set the material of the part to Neon
-- Finish the recording, committing the changes to the history
ChangeHistoryService:FinishRecording(recording, Enum.FinishRecordingOperation.Commit)

Publishing Plugins

As with models, meshes, images, and animations, you can publish plugins to Roblox to make them easy to reuse from the Toolbox. In addition, you can give other creators the ability to purchase and/or install your plugins by publishing them to the Creator Marketplace with supplementary thumbnails that provide visual information on the plugin's functionality. The minimum amount you can sell plugins is 100 Robux.

To publish a plugin:

  1. In the Explorer window, right-click on the plugin script you want to publish to Roblox. A contextual menu displays.

  2. Select Publish as Plugin. The Asset Configuration window opens.

  3. (Optional) In the upper-left corner of the window, click the image to upload a 512×512 image.

  4. Fill in the following fields:

    • Name: A title for your plugin.
    • Description: A description that describes what a potential user should expect the plugin to do.
    • Creator: The creator you'd like to attribute as the creator of the plugin. If you are using Team Create, every creator appears, otherwise "Me" is the only option.
  5. (Optional) If you are ID or phone verified, click the + button to add up to 5 supplementary thumbnails for your plugin.

  6. (Optional) Enable the Distribute on Marketplace toggle to publish your plugin to the Creator Marketplace. If you have previously verified your account, the Price field becomes available.

  7. (Optional) In the Price field, input the amount of Robux you want to charge for the plugin. If you keep the default value of 0, the plugin is free to all creators.

  8. Click the Submit button. Your plugin is now available to you in the Toolbox.

Managing Plugins

To manage a plugin after you install it:

  1. Click the Manage Plugins button in the Plugins tab to open the Plugins Management window.

  2. For the plugin you want to manage, use the following options.

    1. Update – Update the plugin to its latest published version. If this button isn't visible, the plugin is up-to-date.
    2. Active – Toggles whether the plugin is active or not.
    3. Details / Uninstall – Opens a menu to view the plugin's details or uninstall it.
