Potassium is a kernel-level Roblox script executor for Lua execution on Windows. It attaches to the Roblox client and runs user-supplied Lua scripts through an external GUI, targeting desktop use rather than mobile.

The tool centers on script execution through kernel-level operation, with an external GUI for loading and managing scripts. Reported functions include straightforward script loading, keyless access with no key system, and documentation plus a Discord support channel for setup questions. Marketing claims list UNC and sUNC coverage, which describe how closely the executor matches standard Roblox Lua behavior during injection. Access is commonly framed as a one-time lifetime purchase, though pricing and availability can vary by source.
The executor is built for the Windows desktop Roblox client. There is no verified mobile build, so treat it as a PC-only injection tool. Because it runs at kernel level, Windows Defender or third-party antivirus software may raise an AV warning or false positive during installation. Behavior depends on your Windows version and current Roblox client build.
Roblox ships on a regular patch cycle, and any executor must be rebuilt to match each client update. A channel build mismatch is the usual cause of injection failure or a non-working state after Roblox patches. Verify that the current build matches your Roblox version before installing, since the access model and working status can shift after each update. Use only the official source and documentation to confirm the latest build rather than unofficial mirrors.
Confirm the working build status against your client version before each session, and reference official documentation when a script fails to run or the executor reports a mismatch.
