Tests Status CII Best Practices Build Status Total alerts TODO counter XXX counter

Next release will be 5.5.0, current git is 5.4.3 and the latest packaged version(s) See the Release downloads page.

r2 is a rewrite from scratch of radare. It provies a set of libraries, tools and plugins to ease reverse engineering tasks.

The radare project started as a simple command-line hexadecimal editor focused on forensics, over time more features were added to support a scriptable command-line low level tool to edit from local hard drives, kernel memory, programs, remote gdb servers and be able to analyze, emulate, debug, modify and disassemble any binary.


git clone


Most of the plugins you need may be available in the stock r2 installation, but you can find more in the r2pm package manager.

r2pm update          # initialize and update the package database
r2pm install [pkg]   # installs the package

Some of the most installed packages are:

  • radius fast symbolic execution engine based on boolector and r2
  • r2ghidra the native ghidra decompiler plugin:
  • esilsolve symbolic execution r2 plugin based on esil and z3
  • r2dec decompiler based on r2 written in js
  • r2frida the frida io plugin
    r2 frida://0
  • iaito - official graphical interface (Qt)
