Bytecode.
Obfuscated.

Grunteon is the 3rd generation JVM bytecode obfuscator. Written in Kotlin. Engineered for programmability and total control.

Roadmap

The path to version 3.0.0 and beyond.

Updated: Nov 2025

Control-flow

Obfuscation of flow logic to disrupt decompilation and analysis tools.

Programmable Config

A completely programmable configuration system and process pipeline.

Anti-Analysis

Redirects and anti-static analysis techniques to protect integrity.

Resource Mgmt

Advanced handling and obfuscation of non-code resources.

Phantom Classes

Manipulation of class hierarchy and generation of phantom classes.

Encryption

Robust string and number encryption algorithms.

Legacy & Evolution

From lightweight stability to total programmable control.
