Binary Ninja vs RetDec

Binary Ninja is a binary analysis platform that combines an interactive decompiler, disassembler, and debugger. Its decompiler can produce C or BNIL for supported architectures, and users can switch between those outputs. The API provides C++, Python, and Rust bindings for automating workflows inside or outside the interface. A native debugger supports local and remote sessions on Windows, macOS, and Linux. Paid editions support plugins managed through an in-client Plugin Manager; plugins are not available in the Free edition. The browser-based Cloud version supports all architectures but requires submitted binaries and has performance limits, with no API or plugins. The free desktop edition is for evaluation or non-commercial use and lacks API access; the Free plan lists five decompilation architectures, while desktop details state four. Paid perpetual client licenses start at $199, paid once for Personal, with one year of updates and non-commercial use. Higher tiers add commercial use, more architectures, or remote project features. Binary Ninja is made by Vector 35.

RetDec is a free machine-code decompiler based on LLVM that reconstructs functions, types, and higher-level constructs as C or a Python-like language. It supports ELF, PE, Mach-O, COFF, AR archives, Intel HEX, and raw machine code, plus 32-bit Intel x86, ARM, MIPS, PIC32, and PowerPC, and 64-bit x86-64 and ARM64. Analysis includes static executable inspection, compiler and packer detection, and loading and instruction decoding. RetDec can use DWARF and PDB debugging information, reconstruct C++ class hierarchies from RTTI and vtables, and demangle GCC, MSVC, and Borland symbols. An integrated disassembler can generate call graphs, control-flow graphs, and statistics. It can be downloaded as a pre-built package, built from source, or run in Docker; related repositories provide IDA and Radare2 plugins. The project lists Windows 7 or later, Linux, and macOS, with experimental FreeBSD support. Installation requires about 5 to 6 GB of free disk space. The project says development is very limited, with issue responses potentially delayed up to one quarter.
