Open Source & Free: Licensed under MIT, free to use and modify.
Powerful Features: Delivers obfuscation and code protection comparable to commercial tools.
Unity-First Design: Deeply optimized for Unity workflows. Automatically handles all edge cases (e.g., preserving MonoBehaviour names) except reflection (due to technical limitations). Near-zero configuration required.
Battle-Tested: Verified by 3,000+ automated test cases covering virtually all common code patterns.
Hot Reload Ready: Fully compatible with leading hot-reload solutions like HybridCLR and xLua.
Agile Development: Rapid bug fixes, prompt feature updates, and immediate support for the latest Unity/Unity Engine changes.

Features

Symbol Obfuscation: Supports comprehensive configuration rules and incremental obfuscation for flexible and efficient code protection.
Constant Obfuscation: Obfuscates constants such as int, long, float, double, string and array to prevent reverse engineering.
Variable Memory Encryption: Encrypts variables in memory to enhance runtime security.
Eval stack Obfuscation: Obfuscates eval stack variable to prevent reverse engineering.
Expression Obfuscation: Obfuscate complex expressions for enhanced protection.
Function Call Obfuscation: Scrambles function call structures to increase cracking difficulty.
Control Flow Obfuscation: Disrupt code flow to deter reverse engineering.
Randomized Encryption VM: Generates randomized virtual machines to thwart decompilation and cracking tools.
Static and Dynamic Decryption: Combines static and dynamic decryption to resist offline static analysis. Obfuscation Polymorphism: Generates different obfuscated code by configuring different generation keys and randomization seeds.
Garbage Code Generation: Supports various types of low-quality code generation to improve App Store and Google Play review pass rates
Seamless Unity Integration: Deeply integrated with Unity workflows, requiring minimal configuration to get started.
Hot Update Compatibility: Fully supports hot update frameworks like HybridCLR, xLua, and Puerts, ensuring compatibility with dynamic code updates.
DOTS Compatibility: Works seamlessly across all DOTS versions with zero configuration required.
