r2 is a rewrite from scratch of radare in order to provide a set of libraries and tools to work with binary files

This is the rewrite of radare (1.x branch) to provide a framework with a set of libraries and programs to work with binary data.

Radare project started as a forensics tool, an scriptable commandline hexadecimal editor able to open disk files, but later support for analyzing binaries, disassembling code, debugging programs, attaching to remote gdb servers, ..

radare2 is portable.


6502, 8051, CRIS, H8/300, LH5801, LH5801, T8200, arc, arm, avr, bf, blackfin, csr, dalvik, dcpu16, gameboy, i386, i4004, i8080, m68k, malbolge, mips, mips, msil, nios II, powerpc, rar, sh, snes, sparc, tms320 (c54x c55x c55+), x86-64, zimg.

File Formats:

bios, dex, elf, elf64, filesystem, java, fatmach0, mach0, mach0-64, MZ, PE, PE+, TE, COFF, plan9, bios, dyldcache, Gameboy and Nintendo DS ROMs

Operating Systems:

Android, GNU/Linux, [Net|Free|Open]BSD, iOS, OSX, QNX, w32, w64, Solaris, Haiku, FirefoxOS


Vala/Genie, Python (2, 3), NodeJS, LUA, Go, Perl, Guile, php5, newlisp, Ruby, Java, OCAML, ...


radare2 can be built without any special dependency, just use make and get a working toolchain (gcc, clang, tcc, ..)

Optionally you can use libewf for loading EnCase disk images.

To build the bindings you need latest valabind, g++ and swig2.


The easiest way to install radare2 from git is by running the following command:

$ sys/


In case of a polluted filesystem you can uninstall the current version or remove all previous installations:

$ make uninstall
$ make purge


All language bindings are under the r2-bindings directory. You will need to install swig2 and valabind in order to build the bindings for Python, LUA, etc..

APIs are defined in vapi files which are then translated to swig interfaces, nodejs-ffi or other and then compiled.

The easiest way to install the python bindings is to run:

$ sys/

If you want to use the NodeJS bindings just do:

$ npm install radare2.js

To specify the installed version of radare2:

$ npm install radare2.js@0.9.2


There is a test suite that can be retrieved by running:

$ make tests


There is no formal documentation of r2 yet. Not all commands are compatible with radare1, so the best way to learn how to do stuff in r2 is by reading the examples from the web and appending '?' to every command you are interested in.

Commands are small mnemonics of few characters and there is some extra syntax sugar that makes the shell much more pleasant for scripting and interacting with the apis.


radare2 comes with an embedded webserver that serves a pure html/js interface that sends ajax queries to the core and aims to implement an usable UI for phones, tablets and desktops.

$ r2 -c=H /bin/ls

To use the webserver on Windows, you require a cmd instance with administrator rights. To start the webserver use command in the project root.

radare2.exe -c=H rax2.exe
