🔥 Prometheus

Prometheus is a Lua obfuscator written in pure Lua.

This project was inspired by the amazing javascript-obfuscator.
It can currently obfuscate Lua51 and Roblox's LuaU, however LuaU support is not finished yet.

You can find the full Documentation including a getting started guide here.

Prometheus has an official Discord server.
