Obfuscate in 3 Steps
Step 1: Paste Your Code
Visit roxerion.com/obfuscation and paste your Lua script into the editor.
Step 2: Click Obfuscate
Hit the obfuscate button. Your script will be processed in under 100 milliseconds.
Step 3: Download
Download the protected .lua file. It's ready to use immediately.
What Protection Do You Get?
The free tier includes the full protection stack:
🔐 VM Protection
Your code is compiled into custom bytecode that runs on a private virtual machine. This is the same technique used by industry-leading obfuscators.
🔤 String Encryption
All strings are encrypted with RC4 and fragmented keys. They're only decrypted at runtime when needed.
🔀 Control Flow Flattening
Your code's execution order is scrambled into a state machine with encrypted transitions.
🛡️ Anti-Tamper
Integrity checks detect if the code has been modified, preventing patching attacks.
💀 Dead Code Injection
Realistic fake code is injected to confuse reverse-engineering attempts.
🎭 Opaque Predicates
Mathematical expressions that always evaluate the same way, but are difficult for automated tools to simplify.
Free vs. Premium
| Feature | Free | Premium |
|---|---|---|
| VM Protection | ✅ | ✅ |
| String Encryption | ✅ | ✅ |
| Control Flow | ✅ | ✅ |
| Anti-Tamper | ✅ | ✅ |
| Dead Code | ✅ | ✅ |
| Processing Speed | ⚡ <100ms | ⚡ <100ms |
| In-game Watermark | Small toast | None |
The only difference? The free tier adds a small, non-intrusive toast notification that appears once when the script runs. Premium removes this watermark.
Why RoxGuard is Different
Speed
Most obfuscators take 2-10 seconds. RoxGuard's C++ backend processes scripts in 50-100ms — that's 30-60x faster.
No Account Required
Paste, click, download. No signup, no API keys, no waiting in queue.
Roblox Compatible
Output is tested and compatible with all major Roblox executors. No bit32 dependency issues.
Always Available
No rate limits on the free tier. Obfuscate as many scripts as you need.
Example
Input (readable):
local Players = game:GetService("Players")
local player = Players.LocalPlayer
player.CharacterAdded:Connect(function(char)
char.Humanoid.WalkSpeed = 50
end)
print("Speed hack loaded!")
Output (protected):
-- Protected by RoxGuard | roxerion.com
local v1={} local v2=string.char local v3=...
-- (thousands of lines of VM bytecode)
The output is functionally identical but completely unreadable.
