About Capstone
Capstone is a lightweight, multi-platform, multi-architecture disassembly framework. It provides a clean, simple API to disassemble binary code into human-readable assembly for x86 (16/32/64-bit), ARM, ARM64, MIPS, PowerPC, SPARC, SystemZ, XCore, M68K, TMS320C64x, M680x, and EVM architectures. Capstone is the disassembly engine embedded in many major security tools including Ghidra, radare2/rizin, Cutter, Binary Ninja, and dozens of others. Its design emphasizes thread safety, zero external dependencies, and rich detail extraction - each disassembled instruction includes operand details, register access information, and instruction groups. Bindings are available for Python, Java, Go, Ruby, Rust, OCaml, and many other languages, making it the standard building block for custom disassembly and binary analysis tools.
About Radare2
Radare2 is a portable reverse engineering framework that integrates disassembly, debugging, analysis, patching, and scripting capabilities in a single command-line interface. Known for its extensibility and modularity, it supports a wide range of binary formats and architectures. Written in C, Radare2 is a preferred tool among security researchers and reverse engineers for its powerful analysis features and cross-platform compatibility.
