Radare2 vs Rizin
GitHub Stats
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.
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.
