What is it?

Rizin is a reverse engineering framework forked from radare2, with an emphasis on usability, features and code cleanliness. It can analyze binaries, disassemble code, debug programs, serve as a forensic tool, and act as a scriptable command-line hexadecimal editor that can open disk files.

The framework covers a wide range of targets. It parses common executable formats such as ELF, Mach-O, PE and DEX, and supports dozens of CPU architectures from x86-64 and ARM to MIPS, RISC-V and many embedded and retro processors. It runs on Windows, macOS, Linux, the BSDs, Android, and several other UNIX-like systems.

Beyond the main rizin shell, the project ships standalone tools such as rz-bin for binary metadata, rz-asm for assembling and disassembling, rz-find for binary pattern search, and rz-diff for comparing binaries. Scripting access from Python, Rust, Go and other languages is available through rzpipe. It is built with meson.

Key features

  • 01Disassembles and analyzes code across many CPU architectures, including x86-64, ARM64, RISC-V and MIPS.
  • 02Parses executable and binary formats such as ELF, Mach-O, PE and DEX.
  • 03Provides a debugger for running and inspecting programs.
  • 04Includes standalone tools like rz-bin, rz-asm, rz-find and rz-diff for use in shell scripts.
  • 05Offers a scriptable command-line hex editor that opens disk files.
  • 06Supports scripting from Python, Rust, Go and other languages via rzpipe.

Use cases

  • Reverse engineering unknown binaries or firmware images.
  • Analyzing malware or exploits during security research.
  • Scripting binary inspection and comparison tasks in automated pipelines.
  • Examining embedded or retro-platform executables across unusual architectures.

Quick start

  1. 1

    Clone the repository from GitHub

    git clone https://github.com/rizinorg/rizin
  2. 2

    Configure the build with meson

    meson setup build
  3. 3

    Compile Rizin

    meson compile -C build
  4. 4

    Install Rizin system-wide

    sudo meson install -C build

Things to know

  • The README documents building from source with meson (version 0.55.0 or newer), so installation takes more setup than a package-manager install.
  • The project is licensed under LGPL-3.0, a copyleft license whose terms apply when you distribute modified library code.
