RetDec is a retargetable machine-code decompiler based on LLVM that converts native binaries back into readable C or Python-like source code. It supports many architectures (x86, ARM, MIPS, PowerPC, x86-64, ARM64) and file formats (ELF, PE, Mach-O, COFF), and includes static analysis, disassembly, and call/control-flow graph generation.

Use cases

• decompile a native binary back to C source code
• analyze malware samples without running them
• recover source from a stripped executable
• disassemble and statically analyze an ELF or PE file
• detect compiler and packer used to build a binary
• generate call graphs and control-flow graphs from a binary
• demangle C++ symbols from GCC or MSVC binaries

When to choose

• you need a free, open-source decompiler supporting many architectures and file formats
• you want scriptable, command-line binary analysis or integration into a reverse-engineering pipeline
• you need to recover high-level code from binaries without IDA Pro or Ghidra
• you want static analysis features like packer detection and library-code removal

When to avoid

• you need actively developed features or fast issue resolution - the project is in limited maintenance mode
• you need a polished interactive GUI decompiler experience
• you only target a single architecture where a specialized decompiler may perform better
• you need decompilation of modern obfuscated or heavily optimized code with best-in-class output quality
