Radare2: Libre Reversing Framework for Unix Geeks

Latest packaged version Tests Status build tcc CII Best Practices Build Status Discord

See the Releases page for downloads. The current git master branch is 5.8.9, next will be 5.9.0.

  • Since r2-5.6.0 all the patch releases are abi stable
  • Odd patch versions are used in git builds only, releases use even numbers
  • No need to recompile the plugins, bindings or tools if the major and minor version are the same


r2 is a complete rewrite of radare. It provides a set of libraries, tools and plugins to ease reverse engineering tasks. Distributed mostly under LGPLv3, each plugin can have different licenses (see r2 -L, rasm2 -L, ...).

The radare project started as a simple command-line hexadecimal editor focused on forensics. Today, r2 is a featureful low-level command-line tool with support for scripting with the embedded Javascript interpreter or via r2pipe.

r2 can edit files on local hard drives, view kernel memory, and debug programs locally or via a remote gdb server. r2's wide architecture support allows you to analyze, emulate, debug, modify, and disassemble any binary.



The recommended way to install radare2 is via Git using acr/make or meson:

git clone

On Windows you may want to use the precompiled builds or the .bat files to compile if you have msvc:

preconfigure.bat       REM setup python, meson, ninja
configure.bat          REM run meson b + vs project
make.bat               REM run ninja -C b
  • r2 can be installed from git or via pip using r2env.
  • Run sys/ for the default acr+make+symlink installation
  • meson/ninja (muon/samu also works) and make builds are supported.
  • Windows builds require meson and msvc or mingw as compilers
  • To uninstall the current build of r2 run make uninstall
  • To uninstall ALL the system installations of r2 do: sudo make purge

Popular Plugins:

Using the r2pm tool you can browse and install many plugins and tools that use radare2.

  • esilsolve: The symbolic execution plugin, based on esil and z3
  • iaito: The official Qt graphical interface
  • keystone Assembler instructions using the Keystone library
  • r2ai Run a Language Model in localhost with Llama inside r2!
  • r2dec: A decompiler based on r2 written in JS, accessed with the pdd command
  • r2diaphora: Diaphora's diffing engine working on top of radare2
  • r2frida: The frida io plugin. Start r2 with r2 frida://0 to use it
  • r2ghidra: The native ghidra decompiler plugin, accessed with the pdg command
  • r2papi High level api on top of r2pipe
  • r2pipe Script radare2 from any programming language
  • r2poke Integration with GNU/Poke for extended binary parsing capabilities
  • r2yara Run Yara from r2 or use r2 primitives from Yara
  • radius2: A fast symbolic execution engine based on boolector and esil


These are the first steps to use r2, read the book or find tutorials for more details

$ r2 /bin/ls   # open file in read-only
> aaa          # analyse the program (r2 -A)
> afl          # list all functions (try aflt, aflm)
> px 32        # print 32 byte hexdump current block
> s sym.main   # seek to main (using flag name)
> f~foo        # filter flags matching 'foo' (internal |grep)
> iS;is        # list sections and symbols (rabin2 -Ss)
> pdf; agf     # disassembly and ascii-art function graph
> oo+;w hello  # reopen in read-write and write a string
> ?*~...       # interactive filter in all command help
> q            # quit

Many plugins are included in r2 by default. But you can extend its capabilities by using the r2pm package manager.

r2pm -s <word>  # search packages matching a word
r2pm -Uci <pkg> # update database and clean install a package
r2pm -u <pkg>   # uninstall the given package
r2pm -l <pkg>   # list installed packages

Alternatively you can use r2env to switch between different versions.

pip install -U r2env
r2env init
r2env add radare2@git
