Studio command-line interface

Roblox Studio supports command-line arguments that let you launch it with special functionality, such as opening a specific place or script when Studio starts. The Roblox Studio executable is typically installed in the following locations:

When launched from the command line, Studio pipes verbose logs to stdout that are more detailed than what appears in the Output window. Arguments use a double-dash prefix and are case-insensitive. File paths that contain spaces must be quoted.

Note

Any arguments not documented here are for internal use only and are subject to change without notice.

Open a place

To open a published place, specify the place ID, universe ID, and a task.

Required arguments

Supported tasks

Optional arguments

Examples

# Open the latest version of a place
RobloxStudio.exe --task EditPlace --placeId 74265016723074 --universeId 7127583708

# Open a specific previous version
RobloxStudio.exe --task EditPlaceRevision --placeId 74265016723074 --universeId 7127583708 --placeVersion 2

Open a local file

To open a local place, use --task EditFile with the following argument.

You can also open a local place file by passing the file path as the first positional argument without a flag name.

Examples

# Open a local place file
RobloxStudio.exe --task EditFile --localPlaceFile "Projects\MyGame.rbxl"

# Shorthand
RobloxStudio.exe "Projects\MyGame.rbxl"

Open a script

To open a script, specify the place ID, universe ID, and task as described in the open a place section. Then provide one of the following arguments depending on how you want to open the script.

Optional highlighting

Optionally, highlight specific lines or a character range when opening the script.

Examples

# Open a script by path
RobloxStudio.exe --task EditPlace --placeId 74265016723074 --universeId 7127583708 --openScriptPath Workspace/MyFolder/MyScript

# Open a script by ID
RobloxStudio.exe --task EditPlace --placeId 74265016723074 --universeId 7127583708 --openScriptFromId 604a6aa2-04cc-c820-09b3-a1dc0000537f

# Open a script and highlight specific lines
RobloxStudio.exe --task EditPlace --placeId 74265016723074 --universeId 7127583708 --openScriptPath Workspace/MyFolder/MyScript --startLine 1 --endLine 5

# Open a script and highlight a character range
RobloxStudio.exe --task EditPlace --placeId 74265016723074 --universeId 7127583708 --openScriptPath Workspace/MyFolder/MyScript --startLine 1 --endLine 1 --startCharacter 1 --endCharacter 6

Run a script

Use --task RunScript to execute a Luau script after a place finishes loading. Scripts run at the same permission level as the Studio command bar. You can combine this with --placeId and --universeId to run the script in a specific game, or --localPlaceFile to run the script in a local place file. If those arguments are omitted, Studio opens the default empty baseplate template and runs the script there.

Required arguments

Optional arguments

Examples

# Run a script in a specific game and exit when done
RobloxStudio.exe --task RunScript --placeId 74265016723074 --universeId 7127583708 --runScriptFile smokeTest.luau --outputFile out.log --quitAfterExecution

# Run a script in the default Baseplate
RobloxStudio.exe --task RunScript --runScriptFile smokeTest.luau

Try an asset

Use --task TryAsset to insert a specific asset into a baseplate template and open it for editing.

Required arguments

Example

RobloxStudio.exe --task TryAsset --assetId 53326

API dump

Use --api, --fullApi, or --apiV2 to write the Roblox API surface to a file and exit.

Examples

RobloxStudio.exe --api "Desktop/output.json"

RobloxStudio.exe --fullApi "Desktop/output.json"

RobloxStudio.exe --apiV2 "Desktop/output.json"
