Obrion is a free Lua obfuscator that runs in your browser. Obfuscate Roblox scripts, Luau, and Lua code online in seconds - multi-layer protection, no downloads, no setup. Sign in with a free Discord account, paste your script, run a build, and download protected output that behaves identically but is unreadable to anyone who gets their hands on it.
How it works
- Paste your Lua or Luau source into the obfuscator workspace.
- Run a build - the full protection pipeline is always applied.
- Download the protected script and ship it instead of your source.

- First-class Luau support for Roblox, a dedicated Executor target, plus Lua 5.1 and 5.4.
- Free plan with the same full pipeline as paid plans - no weakened output.
- Build history with configuration, sizes, and output for every run.

Frequently asked questions
- Is Obrion a free Roblox obfuscator?
- Yes. Obrion includes a free plan that lets you obfuscate Roblox scripts and Luau code online every month at no cost - no downloads or setup required.
- How do I obfuscate a Roblox script?
- Paste your Lua or Luau source into the Obrion workspace, run a build, and download the protected output. The full obfuscation pipeline is applied automatically.
- Does Obrion support Luau?
- Yes. Obrion has first-class Luau support for Roblox development, plus Lua 5.1 and Lua 5.4 targets for everything else.
- What does a Lua obfuscator protect against?
- Obfuscation raises the cost of reading and copying your code - it renames identifiers, encrypts strings, transforms constants, and flattens control flow so your proprietary game logic stays yours.
- Do I need to install anything to obfuscate Lua online?
- No. Obrion runs entirely in the browser - sign in with a free Discord account, paste your Lua source, and obfuscate it online. No downloads or setup.
- How do I protect my Roblox scripts from being stolen?
- Run your script through a Roblox script obfuscator like Obrion before releasing it. The multi-layer pipeline makes the source unreadable, so copied code can't be understood or reused.
- Does Obrion work with Roblox executors?
- Yes. Pick the Executor target and the output is built for executor environments specifically, so it runs correctly where a Luau build might not.
- What is the best free Roblox script obfuscator?
- Obrion gives you the full multi-layer obfuscation pipeline on the free plan - no weakened output, no per-feature tiers. Paste your script, build, download.
- Is there a free Lua obfuscator I can use online?
- Yes - Obrion is a free Lua obfuscator that runs entirely in the browser. The free plan applies the same multi-layer pipeline as paid plans, so you can obfuscate Lua scripts at no cost.
- Is Obrion a Luau obfuscator too?
- Yes. Obrion is a Luau obfuscator with a dedicated Roblox Luau target, alongside Lua 5.1 and 5.4 - pick the dialect your script runs in and the output is built for that environment.
