Released a small code executor plugin I used

A few days ago I made a custom built in to run elevated RSS code. With a bit of modification, I’m happy to announce to make this plugin open-source and free for anyone to use

(This plugin will run at Identity Level 5, the identity level of any normal plugin)

Features


Full Custom loadstring based code execution

image
This plugin will allow you to run commands in the scope of our command bar, this is not sandboxed meaning you can modify the plugin itself (but I’m not holding any responsibility if you break the command bar)

Direct Integration into LogService

image

You could use this as a complete alternative to the Output Window.


Limitations

Code Execution can only be used in Edit mode due to loadstring restrictions.


This plugin was initially written to run elevated commands at identity level 6, so it’s pretty basic in most departments, however I may or may not be writing a much more advanced command utility in the near future

Enjoy!

Why would we need this is if roblox already has a built in command bar?

This plugin was originally written to run as a custom BuiltIn, allowing me to execute RobloxScriptSecurity code.
