Make your Luau scripts
impossible to steal.
A layered protection engine: bytecode virtualization, runtime-derived keys, anti-hook and anti-tamper safeguards, and metamorphic output — every build is structurally unique. Paste your code, get a protected file in seconds.
Protection built for serious targets.
Every build is validated end-to-end against the real Luau interpreter — thousands of differential tests confirm the protected script behaves exactly like the original.
Bytecode virtualization
Whole functions are lifted into a custom virtual machine. The original source-level logic simply isn't in the output anymore.
Encrypted VM loader
The interpreter ships encrypted and is reconstructed at load. The output on disk is not directly readable execution material.
Anti-hook & anti-tamper
The engine binds decryption to the integrity of the runtime it loads into. A modified environment produces useless output. No clean data to walk away with.
Constant & string encryption
Strings, numbers, property names and constants are encrypted and fragmented. Nothing readable survives a scan of the file.
Metamorphic output
Structural details are randomized per build — signatures and tools tuned to one output do not transfer to the next.
Verified correct
Each build is validated automatically. The engine only parses and transforms your code — it never runs it.
