title: Studio plugins
description: Explains how to create, publish, and monetize extensions to Studio that add custom functionality.
---
A **plugin** is an extension that adds additional features or functionality to Studio. You can [install](../production/creator-store.md#find-assets) community-made plugins from the Creator Store, or you can [create](#create-new-plugins) and [publish](#upload-distribute-and-monetize-plugins) your own to the [Toolbox](../projects/assets/toolbox.md) to use across your experiences.
If you choose to also distribute your plugins to the Creator Store, you can either offer them for free or sell them for **United States Dollars**. Roblox offers a market-leading revenue share for these sales, as only taxes and payment processing fees are deducted. For more information on selling plugins, see [Selling on the Creator Store](../production/sell-on-creator-store.md).
## Create new plugins
You can create your own plugins to improve your workflow in Studio. The following code sample is a plugin called **AddEmptyScript** that inserts an empty script as the child of an object or in `Class.ServerScriptService`. The following sections explain the major parts to creating this plugin.
To begin, you should enable **Plugin Debugging Enabled** in the **Studio** section of Studio's settings. This will expose the `Class.PluginDebugService` in Studio which provides real-time debugging for your plugin's code and makes it easier to reload and save your plugin.
```lua title="AddEmptyScript Plugin"
local ChangeHistoryService = game:GetService("ChangeHistoryService")
local Selection = game:GetService("Selection")
local ServerScriptService = game:GetService("ServerScriptService")
-- Create a new toolbar section and Plugins menu folder titled "Custom"
local toolbar = plugin:CreateToolbar("Custom")
-- Add a toolbar button labeled "Empty Script"
local newScriptButton = toolbar:CreateButton("Empty Script", "Create an empty script", "rbxassetid://14978048121")
-- Make button clickable even if 3D viewport is hidden
newScriptButton.ClickableWhenViewportHidden = true
local function onPluginButtonClicked()
local selectedObjects = Selection:Get()
local parent = ServerScriptService
if #selectedObjects > 0 then
parent = selectedObjects[1]
end
local newScript = Instance.new("Script")
newScript.Source = ""
newScript.Parent = parent
ChangeHistoryService:SetWaypoint("Added new empty script")
end
newScriptButton.Click:Connect(onPluginButtonClicked)
```
### Save plugin script
To create a plugin, first create a `Class.Script` and save it locally.
1. Insert a new `Class.Script` inside `Class.ServerStorage` and rename it to **AddEmptyScript**.

2. Copy and paste the **AddEmptyScript Plugin** code into the new script.
3. With the new script selected in the **Explorer** window, select **Save as Local Plugin** from Studio's **Plugins** menu.
4. In the popup window, click **Save** to insert the plugin script into your local **Plugins** folder of the Studio installation.
5. The plugin should appear in `Class.PluginDebugService` and start running.
6. <Chip label="IMPORTANT" size="small" variant="outlined" color="warning" /> Delete the original script in `Class.ServerStorage` and work from the `AddEmptyScript` plugin inside `Class.PluginDebugService`, otherwise you may end up applying changes to the wrong script.

<Alert severity="info">
To update a specific plugin within `Class.PluginDebugService`, right‑click it and select **Save&nbsp;and&nbsp;Reload&nbsp;Plugin** from the context menu. If you simply want to reload the plugin, for example to step through a section of code using a breakpoint without saving the plugin, right‑click it and select **Reload&nbsp;Plugin**.
At the broadest level, you can also update **all** plugins by right-clicking `Class.PluginDebugService` and selecting **Save&nbsp;and&nbsp;Reload&nbsp;All&nbsp;Plugins&nbsp;in&nbsp;Debugger** (shortcut <kbd>Ctrl</kbd><kbd>Shift</kbd><kbd>L</kbd> or <kbd>⌘</kbd><kbd>Shift</kbd><kbd>L</kbd>).
</Alert>
### Add toolbar button
To add a button for your plugin to the **Plugins** tab of the Studio toolbar, use the `Class.Plugin:CreateToolbar()` and `Class.PluginToolbar:CreateButton()` methods. In the code for **AddEmptyScript**, line 5 creates a new section in the toolbar and **Plugins** menu folder titled **Custom**, while line 8 creates a button labeled **Empty Script**.
<img src="../assets/studio/general/Toolbar-Custom-Plugin-Button.png" width="800" alt="New plugin button added to toolbar in Studio" />
### Execute code on click
To make the plugin execute code when a user clicks the toolbar button, connect a function to the button's `Class.PluginToolbarButton.Click` event. In the code for **AddEmptyScript**, the connecting function is `onPluginButtonClicked()`.
### Check user selection
To modify a plugin's behavior based on what the user has selected, use the `Class.Selection` service. The `onPluginButtonClicked()` function checks if the user has anything selected and creates the new script as its child instead of inside `Class.ServerScriptService`. If the user doesn't have anything selected, it creates the new script in `Class.ServerScriptService`.
<img src="../assets/studio/explorer/Plugin-Inserted-Script.png" width="320" />
### Support undo and redo
Use `Class.ChangeHistoryService` to allow users to undo and redo changes made by a plugin within an experience. In your script, set the plugin to call `Class.ChangeHistoryService:TryBeginRecording()` and store the identifier assigned to the API call before making changes. Then set the plugin to call `Class.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 `Class.ChangeHistoryService` to record and manage the changes made by the plugin:
```lua title="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
button.Click:Connect(function()
local parts = {}
for _, part in Selection:Get() do
if part:IsA("BasePart") then
parts[#parts + 1] = part
end
end
if #parts < 1 then
-- Nothing to do!
return
end
-- 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
-- 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
return
end
-- Iterate through the selected parts
for _, part in parts do
part.Material = Enum.Material.Neon -- Set the material of the part to Neon
end
-- Finish the recording, committing the changes to the history
ChangeHistoryService:FinishRecording(recording, Enum.FinishRecordingOperation.Commit)
end)
```
## Upload, distribute, and monetize plugins
As with [models](../parts/models.md), [meshes](../parts/meshes.md), [images](../parts/textures-decals.md), and [animations](../animation/editor.md#creating-an-animation), you can distribute plugins to Roblox to make them easy to reuse from the [Toolbox](../projects/assets/toolbox.md). You can choose to make them publicly available to all other creators on the [Creator Store](../production/creator-store.md), or to distribute them privately for your own use. If you choose to distribute your plugin publicly, you can set a price at which to sell it to other creators.
<Alert severity="info">
The only way to distribute and set a price for a plugin is through the Creator Dashboard. You can always upload a plugin using this process and, if age-verified, monetize it later from the dashboard. For instructions on this process, see [Distributing Assets](../production/creator-store.md#through-creator-dashboard).
</Alert>
To distribute a plugin:
1. In the [Explorer](./explorer.md) window, select a plugin script and then select **Publish as Plugin** from Studio's **Plugins** menu.
1. <Chip label="OPTIONAL" size="small" variant="outlined" /> In the upper-left corner of the asset configuration window, click the image to upload a 512&times;512 image.
1. 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.
1. Click the **Submit** button. Your plugin is now available to you in the **Inventory** and **Creations** tabs of the [Toolbox](../projects/assets/toolbox.md).
1. Click the link to Creator Dashboard to [configure distribution](../production/creator-store.md#through-creator-dashboard).
<Alert severity="info">
To publicly distribute or monetize a plugin you have previously uploaded, use the [Creations](https://create.roblox.com/dashboard/creations?activeTab=Model) section of the Creator Dashboard. For more information, see [Distributing Assets](../production/creator-store.md).
