A libre, Unix-like reverse engineering framework and command-line toolset for analyzing, debugging, and modifying binaries.
Radare2 is a libre reverse engineering framework and command-line toolset for analyzing, debugging, and modifying binary files. It provides a comprehensive environment for low-level tasks like disassembly, emulation, forensics, and scripting, supporting a wide range of architectures and file formats. It solves the need for a powerful, open-source alternative to proprietary reverse engineering tools.
Security researchers, malware analysts, forensic investigators, and software developers who need to perform deep binary analysis, vulnerability research, or low-level debugging on various platforms.
Developers choose Radare2 for its unparalleled flexibility, extensive architecture support, and scriptable nature—all under a libre license. Its modular design and active plugin ecosystem allow for deep customization, making it a versatile tool for complex reverse engineering workflows.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Supports over 50 CPU architectures and numerous file formats listed in the README, enabling analysis of everything from legacy systems to modern embedded devices.
Features an embedded JavaScript interpreter and r2pipe for automation from any language, plus the r2pm package manager for extensible plugins like decompilers and diffing engines.
Runs on Windows, Linux, macOS, BSD, Android, and more with a uniform command-line interface, ensuring tool availability across diverse environments.
Integrates disassembly, emulation, debugging, and forensics into a single toolset, reducing reliance on multiple specialized tools for low-level tasks.
The command-line interface has myriad cryptic commands (e.g., 'aaa', 'pdf'), requiring users to study the official book or tutorials extensively, as hinted in the Resources section.
Advanced features like decompilers (e.g., r2ghidra) must be installed separately via r2pm, adding setup complexity and potential dependency issues.
While resources exist, the README directs users to books, videos, blogs, and community chats, making it challenging to find consolidated, up-to-date guidance.
