Open-source alternatives to Python Uncompyle6

This project is a desktop application designed for the reverse engineering and inspection of compiled Java code. It functions as a graphical interface that translates Java bytecode back into readable source code, allowing users to examine the internal logic of class files and archives when original source files are unavailable. The tool provides a structured environment for navigating complex file hierarchies, including nested archives like JAR and WAR files. By maintaining an in-memory representation of loaded classes, it enables rapid searching and cross-referencing of code elements. The ap

Jadx is a comprehensive Java decompilation suite designed to transform compiled binary application files into readable source code. It functions as a static analysis workbench, providing a graphical interface for navigating, searching, and inspecting the internal logic of complex software packages. By utilizing a bytecode-to-Java pipeline, the project reconstructs high-level logical structures from low-level binary instructions, making it a primary tool for Android application reverse engineering. The project distinguishes itself through a sophisticated control flow reconstruction engine and

radare2 is a reverse engineering framework and binary analysis toolset. It functions as a multi-architecture disassembler, low-level binary debugger, and hexadecimal editor for inspecting executable structures and interpreting machine code when original source files are unavailable. The framework provides capabilities for decompiling machine instructions, performing symbolic analysis, and diffing binary files to identify structural changes across versions. It also includes a digital forensic analyzer and disk analyzer for browsing filesystem formats in userland. The toolset supports binary p
