How to protect a Roblox script
Obfuscation, a loader, keys, and revoke. None of that makes client Lua unbreakable.

What is Roblox script protection?
It is the set of controls that keep paying customers from casually copying your Lua/Luau, running it after a refund, or handing a working file to a friend. It is not a guarantee that nobody can recover logic from a client-side script.
Threat model
Assume the buyer can:
- Save whatever their executor downloaded
- Share a key or a dumped payload in Discord
- Run the script in a different game than you intended
- Try to skip ads or replay a grant
You cannot stop a skilled reverse engineer with unlimited time. You can make casual leaks expensive, bind a key to a device, lock a PlaceId, and cut off the next download after you revoke access.
Why source is exposed
Executor scripts run on the client. If you paste a full source file into Discord, that file is the product. A loader plus server-side auth changes the default: buyers receive a short stub, not your project source.
Where obfuscation helps
Obfuscation rewrites Lua so humans and naive dumpers struggle to read it. KeyForge's default provider is wYnFuscate, with plan quotas on Starter, Basic, and Creator, and unlimited wYnFuscate on Scale and Enterprise. Obfuscation does not authenticate a user.
See obfuscation vs licensing for the split.
Where licensing and authentication help
A key is a grant: timed, permanent, execution-capped, Discord-mapped, or device-bound after first run. The loader asks KeyForge whether that grant is still valid before delivery. Revoking the key stops future authentications even if someone still has an old dump.
Details: Roblox script licensing explained.
Server-side validation you actually have
- Key status: active, expired, revoked
- HWID / device bind after first successful run
- Optional PlaceId / game routing so a loader only serves in the games you configured
- Heartbeat and session expiry on the delivery path
These checks live on KeyForge's servers. They cannot inspect every line of Lua the executor already ran.
Customer management
Issue keys from the dashboard, Discord panels, or ad-link grants. Reset HWID from Discord when a real customer changes devices. Watch analytics for reuse. When a key is shared, revoke it instead of arguing in DMs.
Limitations
- Client Lua can be dumped. Do not sell a script as "uncrackable."
- A revoked key does not erase files already on disk.
- Shared Wi-Fi and VPNs can confuse naive IP-only locks. KeyForge binds devices at the key/HWID layer for script access, which is different from website signup rules.
How KeyForge fits
Paste source into a project, protect it, copy the loader, and hand out keys. Starter is free with 1 project, 3 scripts, 50 keys, and 20 wYnFuscate obfuscations per month. Paid plans raise those caps. Getting started: public setup guide.
Can I make a Roblox script impossible to leak?
No. If Lua/Luau runs on the client, a determined person can dump or reconstruct it. Protection reduces casual copying and lets you revoke access; it does not create perfect secrecy.
Is obfuscation enough to protect a paid script?
Obfuscation makes source harder to read. It does not control who can run the script, expire access, or stop a dumped build from being shared. Pair it with authentication and keys.
What does a loader actually do?
A short loadstring contacts your backend, proves a key or other grant, then downloads the protected payload. Buyers never receive your original source file from you.
