Obfuscator Free | Plug and Play Code Protection | v2026

📄 Documentation 💬 Forum ▶️ Demo 🟣 Discord

Ship your game. Keep your code yours.

Your Unity game can be analyzed, copied or tampered with after it leaves your hands. GuardingPearSoftware's Obfuscator is a build-time tool making your compiled code significantly harder to read, understand, and reverse engineer – so the work you shipped stays yours.

✔️ Make hacking and cloning harder

✔️ Keep your logic and algorithms yours

✔️ Raise the cost of reverse engineering

✔️ Keep shipping your way – runs automatically on build

Trusted by developers for 10+ years. 4000+ projects protected, from solo indies to enterprise studios.

Your game is ready to ship. Is your code?

👀 SEE IT IN ACTION

Prefer to test the result yourself before downloading? Grab the demo builds (Mono and IL2CPP, normal vs. obfuscated) and compare the same game before and after protection.

🔑 OBFUSCATION FEATURES

Built specifically for Unity, the Obfuscator understands Unity's unique characteristics – MonoBehaviours, ScriptableObjects, Serialization, and Reflection – giving you a powerful yet easy, out-of-the-box tool that won't break your project.

Supported member obfuscation:

-> Classes (MonoBehaviour and ScriptableObject subclasses are part of Pro)

-> Methods

-> Fields

-> Properties

-> Events

For more obfuscation and security features – like namespace, MonoBehaviour and ScriptableObject obfuscation, string obfuscation, control flow obfuscation and anti tampering – have a look at Obfuscator Pro. To compare all features please go here.

⚙️ INTEGRATION

Integration is plug & play. Enable it once, and obfuscation runs automatically every time you build – it hooks directly into the Unity build pipeline and applies protection there.

The entire obfuscation workflow is fully customizable and clearly logged, so you always know what happened and why.

A StackTrace de-obfuscation tool is included, letting you restore and debug crash logs from your secured builds – so shipping protected code doesn't cost you your ability to debug it.

📦 PLATFORMS & COMPATIBILITY

-> All platforms Unity supports

-> Mono and IL2CPP scripting backends

-> Works within the standard or custom Unity build pipelines

⭐ WHY CHOOSE OBFUSCATOR FREE

-> Unity-first: Generic obfuscators break on Unity references or serialization and reflection. This one is built for Unity, so it doesn't.

-> Trust-first: The obfuscator itself is not obfuscated. You can inspect the obfuscator's own assemblies and follow the workflow. Others force you to trust a black box.

-> Actively developed: For 10+ years and regularly updated to keep pace with new Unity versions and evolving threats.

-> Free to start: When you need stronger protection, upgrade to Obfuscator Pro.

📦 EDITIONS

-> Obfuscator Free: Your start into securing your Unity build for free.

-> Obfuscator Pro: High level securing your Unity build, with advanced obfuscation and enterprise hardening features.

-> Obfuscator Source: Everything in Pro plus the full source code for teams that need custom modifications or deeper integration.

❓ FAQ

-> Does it support IL2CPP? Yes. Member obfuscation works on both Mono and IL2CPP.

-> Will it break my game? No. The Obfuscator is Unity-aware and handles serialization and reflection. Reflection-heavy code can be excluded from obfuscation via settings so your project keeps working.

-> Does it support Addressables? Yes. Addressables are fully supported.

-> Can I still debug crashes? Yes. Use the included StackTrace de-obfuscation tool to restore readable stack traces from protected builds.

-> Is it hard to set up? No. Enable it once and it runs automatically on every build.
