Military-grade Luau code obfuscation. Protect your scripts with multi-pass AST transformations, dual VM architectures, and advanced control flow scrambling — completely free.
Every protection method you need, in one place.
Scope-aware renaming of all local variables, function parameters, and loop variables. Roblox globals preserved by default.
XOR-encodes all string literals and injects runtime decoding stubs, making reverse engineering dramatically harder.
Restructures linear code into dispatch-table loops with opaque predicates, breaking decompiler analysis.
Compiles your Luau into bytecode wrapped in a push/pop stack virtual machine with shuffled opcodes.
Register-allocated VM with polymorphic dispatch and encoded bytecode for maximum protection.
Pre-obfuscation validation catches errors early so your protected script always runs correctly.
Optionally collapse your entire script to a single line, reducing size and readability simultaneously.
No subscriptions, no paywalls, no limits. Cosmic Obfuscator is completely free for the Roblox community.
