Boomerang vs JADX

Boomerang is an open-source decompiler that translates supported machine-code binaries into C source code. It supports x86 (IA-32 only), PPC, and ST20 architectures, and accepts ELF, PE, DOS MZ, DOS/4GW LE, and Mach-O files. Users can run it as a command-line tool or a GUI application. The project describes its license as BSD, and the software is free. Build instructions cover Linux, macOS, and Windows, but compiling requires a 64-bit operating system and a C++17 compiler; 32-bit systems are not supported. Documented prerequisites include CMake, Qt5, Capstone, GNU bison, and GNU flex. Precompiled packages are available for release versions, although the project recommends building the development branch from source. Unit and regression tests are provided, but the README says the regression test suite cannot be built on Windows. The maker describes the release as intended for developers and experimenters and warns that large-binary decompilation may disappoint. Decompiled output does not recreate the original source file and may differ from it. The project directs users to its GitHub issue tracker for bug reports.

JADX is a free Apache 2.0 project that turns Android Dex and APK files into Java source code through command-line and graphical tools. It also decompiles AAR, AAB, and ZIP files and decodes AndroidManifest.xml and resources.arsc. An included deobfuscator supports mappings and identifier renaming. The GUI offers syntax highlighting, declaration navigation, usage lookup, and full-text search. Its debugger can step through code, set breakpoints, and modify register values or object fields; this requires adb plus a debuggable app or a rooted device or emulator. JADX can be used as a library in Java projects, and its CLI manages plugins from the marketplace. Downloaded releases require 64-bit Java 11 or later. It runs on Linux, macOS, and Windows. The project warns that decompilation may not recover all code, so errors can occur.
