🐼 Panda Obfuscator v1.3

Panda Obfuscator is a Lua obfuscator written in pure Lua, based on Prometheus. It uses AST-based transformations including Control-Flow Flattening, Constant Encryption, VM virtualization, and hardened handler polymorphism.

Panda Obfuscator targets both Lua 5.1 and Roblox Luau and ships a Xenon-safe preset that avoids high-UNC APIs (debug.sethook, string.dump, hookfunction, getrawmetatable).

Installation

git clone https://github.com/Panda-Repositories/Prometheus-Modified.git
cd Prometheus-Modified

Ready-to-use (Windows)

Run the installer once — it downloads Lua 5.1.5 into .\bin\:

powershell -ExecutionPolicy Bypass -File install.ps1

Then obfuscate with the panda.bat wrapper:

panda.bat --preset Panda-Xenon your_script.lua

Ready-to-use (Linux / macOS)

Install Lua 5.1 via your package manager:

sudo apt install lua5.1         # Debian / Ubuntu
brew install lua@5.1            # macOS

Then run:

chmod +x ./panda.sh
./panda.sh --preset Panda-Xenon your_script.lua

Manual

Requires LuaJIT or Lua 5.1. Binaries: https://sourceforge.net/projects/luabinaries/files/5.1.5/Tools%20Executables/

lua ./cli.lua --preset Medium your_script.lua

Usage

panda.bat --preset Panda-Xenon your_script.lua
panda.bat --preset Panda-Roblox-Strong your_script.lua
panda.bat --preset Medium --out out.lua your_script.lua

Presets

• Minify – whitespace/rename only
• Weak / Medium / Strong – Lua 5.1 pipelines
• LuaU-Safe / LuaU-Typed – Luau pipelines (compat profiles)
• Panda-Xenon – Luau, low-UNC safe for Xenon and similar executors
• Panda-Roblox-Strong – heaviest Luau pipeline with double Vmify

Compatibility profiles

• Lua51 (default)
• LuaU-safe
• LuaU-typed – accepts type annotations; obfuscation strips them

lua ./cli.lua --profile LuaU-safe --LuaU ./your_file.lua
lua ./cli.lua --preset Panda-Xenon ./roblox_script.lua
