Capstone vs Rizin
GitHub Stats
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 Rizin
Rizin is a free and open-source reverse engineering framework, forked from radare2 with a focus on usability, stability, and a cleaner API. It provides a complete binary analysis toolkit including disassembly, debugging, emulation, binary patching, and scripting across dozens of architectures and file formats. Rizin addresses many of radare2's historical pain points - inconsistent command naming, unstable APIs, and steep learning curve - while maintaining the powerful capabilities that made radare2 popular. The Cutter GUI, originally an r2 frontend, is now the official Rizin GUI, providing a modern graphical interface for reverse engineering workflows. Rizin supports x86, ARM, MIPS, RISC-V, PowerPC, and many other architectures, with plugins for additional formats and analysis capabilities.
