radare

Radare, originally known simply as Radare, is a free and open-source reverse engineering framework designed for analyzing binaries and performing low-level data investigations. It provides a collection of tools for disassembly, debugging, patching, data reconstruction, and scripting, intended to support security researchers, software developers, and digital forensics practitioners. The project evolved into radare2, a rewritten, more modular implementation that continues the same mission with broader architecture support and improved extensibility.

Radare2 comprises a command-line interface (r2) with an interactive visual mode, a disassembler (rasm2), a debugger, and various utilities. It supports multiple processor architectures and file formats, enabling static and dynamic analysis, binary instrumentation, and patching. Its extensibility is reinforced by a plugin architecture, bindings for languages such as Python, and the r2pipe protocol, which allows external programs to control radare2.

Radare2 is cross-platform, running on Linux, macOS, Windows, and other Unix-like systems. It is released under free/open-source licenses and is developed by a community of volunteers; its development is hosted on platforms like GitHub, with an active wiki and extensive documentation. The project is widely used in reverse engineering education, security research, vulnerability discovery, and Capture The Flag competitions.
