The sUNC on Xeno Executor is a score people use to describe how well it can run Roblox scripts, and the sources I found put it roughly around 40% to 41% in one review, while another recent source claims 84% UNC and 40% sUNC for Xeno.

What it means

  • sUNC usually refers to a script-compatibility style metric, not an official Roblox standard.
  • Higher numbers generally mean the executor can handle more scripts with fewer errors.
  • In the results I found, Xeno’s reported sUNC varies a lot depending on the source, so treat the number as unstable and unofficial.

Why the numbers differ

  • Executor communities often use different test setups.
  • Some posts are promotional and may inflate performance.
  • Videos and fan pages can report results from different versions, so one build may score differently from another.

Practical take

If you’re asking whether Xeno is “good,” the short answer is that people describe it as a free Roblox executor with mixed but sometimes decent compatibility, not a consistently top-tier one.

Safety note

Using Roblox executors can violate the platform’s rules and may expose you to malware or account bans, especially when downloads come from unofficial sources.

TL;DR: Xeno’s reported sUNC is around 40% in some sources, but claims vary widely, so the number isn’t something you should treat as reliable or official.
