# LuaLock

> LuaLock is a Lua, Luau, and Roblox script obfuscator. It compiles source into a private bytecode format that runs inside an injected virtual machine, generating a unique instruction set per build. Standard Lua decompilers target PUC-Rio bytecode and produce nothing useful against LuaLock output.

LuaLock is not a textual transform (it does not just rename variables or insert junk). It lowers your code into a custom register-based bytecode and ships a generated VM that executes it. Each build remaps opcodes, encrypts constants, and adds tamper-detection guards, so two builds of the same script never look alike. It supports Lua 5.1, 5.3, 5.4, LuaJIT, Luau, and Roblox targets, and is available through a web dashboard, a REST API, and a cross-platform CLI.

Source code is processed in memory and is never written to disk or stored, unless you explicitly opt in to saving a build to your history.

## Key facts

- LuaLock targets: Lua 5.1, Lua 5.3, Lua 5.4, LuaJIT, Luau, and Roblox.
- Output is a self-contained script that runs the original program inside a generated virtual machine.
- The opcode mapping is unique per build, so there is no public decompiler that targets LuaLock output.
- Source and output are not retained by default; saving to history is opt-in.
