Industry-grade Luau protection built around a custom register-based virtual machine. Transform your source into proprietary bytecode that executes inside a purpose-built VM, obscuring your original control flow and logic at runtime.
Each layer independently transforms your Luau source into an unreadable, tamper-resistant form. Stack them together for maximum security.
All string literals are XOR-encrypted with unique per-script keys and decrypted at runtime. Even if a decompiler recovers the bytecode, the strings remain cryptographically obscured.
Restructures function logic into opaque switch-based dispatchers, destroying readability. The original execution order is encoded into a dispatch table that cannot be statically followed.
Numeric and boolean constants are split, encoded, and reassembled through arithmetic chains at runtime. No meaningful literal value is ever stored directly in the output bytecode.
Injects runtime checks that detect debugging tools, modification attempts, and unauthorized access. Any tampering triggers silent self-termination before sensitive logic can be exposed.
Binds the entire script inside a custom register-based VM and interpreter loop. All logic, registers, and opcodes execute inside an isolated virtual environment, eliminating static analysis completely.
Inserts semantically neutral dead code and fake branches to bloat and mislead decompilers. The injected noise is indistinguishable from real logic without full execution tracing.
Strips all meaningful variable and function names, replacing them with opaque, randomized tokens. No symbol in the output carries any semantic relationship to the original source.
Removes unused code paths and optimizes the obfuscated output for minimal overhead and max stealth. The final output is compact, performant, and leaves no structural footprint of the original.

Your protected script never sits in the open. It lives encrypted inside Xemi Vault cold storage and is only released to a client once the environment passes verification — no leaks, no scraped payloads, no cached copies.
Everything developers usually ask before moving their code into XemiLabs.
Vault is encrypted cold storage for your protected scripts. Instead of handing out a file, you store the obfuscated build in Vault and it is streamed to the executing client only when that request checks out.
Before any code is released, we fingerprint the requesting environment — origin, runtime signals, and your configured rules. If it doesn't match what you allow, no bytecode leaves the Vault.
Every account, including the free plan, gets 300 KB of Vault storage at no cost. Paid plans scale that up along with obfuscation limits.
Vault pairs with VM virtualization, anti-tamper and integrity checks, so what reaches memory is virtual bytecode, not readable Luau. Tampering trips the checks and execution halts.
No. Verification adds a few milliseconds and the payload is served from a low-latency edge fetch after the cold-storage read.
Commercial use and obfuscating for clients are available on the Business plan. Full details live on the pricing page.
