Register-Based VM
Compiled to custom bytecode, opcode order and registers shuffled on every build.
Obfuscate Your Roblox Scripts in Seconds — Free
A custom bytecode VM built specifically for Roblox Luau — not a text-obfuscation script wrapping your source in a beautifier-reversible mess.
What actually happens to your script
String & Constant Encryption
Literals are encrypted and decoded at runtime, never stored in the clear.
Control Flow Flattening
Execution paths are flattened so output doesn't map back to your source.
Hook & Tamper Detection
Watches for hooked functions and known dumpers, without breaking legit players.
Chunked Delivery
Large scripts stream in encrypted chunks, so multi-MB files still load reliably.
Per-Recipient Watermarking
Every copy is tagged, so a leak traces back to who leaked it.
Obfuscator FAQ
Is the LuaProtect obfuscator free?
Yes. The register-VM obfuscator is included in the free tier — no credit card required. Paid plans raise script and player limits and unlock additional hardened obfuscation layers.
Does obfuscation slow down my script?
Bytecode virtualization adds interpretation overhead versus native Luau execution, which is true of any VM-based obfuscator. LuaProtect's VM is tuned for Roblox's Luau runtime specifically and includes a performance-safe profile for scripts where raw speed matters more than maximum hardening.
Which Roblox executors are supported?
Obfuscated output runs on all major modern executors, including ones with partial UNC (Unified Naming Convention) coverage like Xeno and Solara — the optional anti-tamper checks are written to fail open rather than break execution when an executor is missing a given function.
How is this different from just minifying or renaming variables?
Minification and identifier renaming are trivially reversible with a beautifier. LuaProtect compiles your script into a custom bytecode format and interprets it through a generated VM whose instruction layout is randomized per build — there's no simple text transform to undo.
