Yub-X is a Roblox script executor that performs Lua injection into the game client. It attaches to a running Roblox process and runs Lua and Luau code inside active experiences, giving users a script execution environment for the Windows client.

The executor centers on fast injection and script execution through a standard inject-and-run workflow. Reported modules include a script hub for loading community scripts, a decompiler reference, and a teleport handler. Access follows a freemium model: a free tier gated by a key system and a premium option that skips key steps. The build references offsets and shuffles handling for compatibility with current client versions, and it advertises stable sUNC-level function support alongside claimed undetected performance.
This tool targets the Windows Roblox client and injects into RobloxPlayerBeta.exe. Mobile support is limited and inconsistent compared with desktop use, so the primary environment is PC. Injection depends on matching current Roblox offsets, so a working session requires the client version and the executor build to align. A version mismatch error indicates the build has not yet caught up with a recent Roblox update.
The current build is aligned to version-ad5d3e2906444472. Because Roblox pushes client updates that shift offsets, the executor requires periodic rebuilds to stay functional, and access can break temporarily after each Roblox patch. A status page and uptime monitoring are used to report the current working state, so checking status before download or injection is the practical way to confirm whether the executor is operational. Update handling focuses on refreshing offsets and shuffles to restore compatibility.
For accurate results, confirm the current status and client version before you attempt to download, install, or inject, since compatibility depends on the executor build matching the running Roblox version.
