Rizin is a free and open-source reverse engineering framework designed for analyzing binaries with speed and precision. It takes a Unix-friendly approach, letting you work directly from the command line without unnecessary overhead, while remaining flexible enough to support graphical interfaces and scripting.

Key capabilities include:

Fast disassembly - Analyze binaries in a fraction of a second from the command line
Cutter GUI - The official graphical interface with freely positionable widgets, advanced graphing, and visualization for complex analysis tasks
Project management - Save and load reverse engineering sessions with a future-proof project system
Redesigned shell - Commands rigorously defined in YAML for accurate help and streamlined workflows
Signature detection - Automatically identify functions in stripped binaries using FLIRT signatures
Package manager - Download, compile, and install plugins across all major platforms

Whether you prefer working in a shell environment or using a graphical interface, Rizin provides a powerful backend for both new and experienced reverse engineers. The framework is actively developed with contributions from the community, making it ideal for binary analysis, vulnerability research, and malware investigation.
