What is a Roblox executor?
An executor is a separate program that runs a script inside the Roblox app. Roblox's rules don't allow them. This guide explains what they are and what the numbers show, and doesn't link to or recommend any.
What an executor is
Roblox games run code written by their developers. A player has no built-in way to run code of their own. An executor is a program from outside Roblox that attaches to the Roblox app and gives it one: you paste a script in, press a button, and the script runs inside the game you are in.
The executor also supplies extra functions that scripts rely on, such as downloading a file or copying to the clipboard. A loadstring works only because the executor provides loadstring and HttpGet.
Which executors players ran scripts with
Each time an executor fetches a script from RoScripts, the request shows which executor sent it. These are the fetches from 23 October to 14 November 2026.
RoScripts is mostly used on computers, so that list leans toward computer executors. On phones the picture is different. Rayfield, a menu library made by the same team as RoScripts, counts the players who run scripts built with it: on 13 November 2026, 49,035 of about 75,800 were on Delta on a phone.
What UNC and sUNC mean
Executors don't all supply the same functions, and scripts break when one is missing. UNC, the Unified Naming Convention, was a list of the functions an executor should have and what to call them. It has been retired. sUNC (senS' Unified Naming Convention) is its replacement: a test that runs each function and checks that it really works, and gives the executor a percentage.
A sUNC score tells you
- How many of the functions scripts use work properly on that executor.
It doesn't tell you
- Whether the program is safe to install.
- Whether Roblox detects it.
Why a script works on one executor and not another
A script written with one executor's functions in mind stops on an executor that lacks them. Some protected scripts go further and check the executor's name before they run, refusing the ones their creator hasn't tested. When Scriptsight ran every script on RoScripts, 31 were turned away by their own protector. Why a script isn't working has the other reasons.
Is an executor safe?
Scriptsight runs scripts, not installers, so RoScripts has no test result for any executor download. What can be said comes from Roblox and from security companies.
"Many exploits are scams to get you to download malware."
In August 2026 Bitdefender reported fake downloads of a well-known executor that installed a remote-access tool and an information stealer. ESET's advice from 2025 is that a site telling you to turn off your antivirus is a warning sign.
A copy of an executor's site is easy to make. Several of the best-known executors have look-alike download sites. Read the address the way you would a Roblox link, and treat any instruction to switch off antivirus or a firewall as a reason to stop.

Questions
Does a higher sUNC score mean an executor is safer?
No. sUNC tests whether an executor's functions work the way scripts expect. It says nothing about what the program does on your device.
Does RoScripts recommend an executor?
No. RoScripts lists which executors exist and whether they are working, and checks scripts. It doesn't test executor downloads and doesn't recommend one.
Can you get banned for using an executor?
Yes. Roblox's rules don't allow exploits, and since 6 May 2025 it has said modified clients risk action up to account termination.
