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

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


It is possible to script and extend r2 using native plugins written in C. Dynamic programming languages can be also used via the r2pipe interface or using the rlang r2pm packages which make the pythonvm run inside radare2.

Some of the languages supported by r2 are: Python, Ruby, JavaScript, Lua, Perl, PHP, Go, Rust, Swift, C#, Java, Shell, OCaml, Haskell, Scheme (Guile), Common Lisp, Clojure, Erlang, D, Vala/Genie, Prolog, Nim, Newlisp...


To learn more about r2 we encourage you to watch youtube talks from r2con. As well as reading blogposts, slides or read the official radare2 book, You can reach us in the following chats:

Install / Update

The recommended way to install or update radare2 from git for single-user systems:

$ sys/

If you don't have root, or just want to install it in your home use:

$ sys/

Note that those scripts will install using configure+make using symlinks, so you don't need to reinstall every time you change something in the builddir.

  • If you don't like symlinks use
    sys/ --install
  • To use capstone5 use the

Alternatively you can also build with meson + ninja:

$ sys/ --prefix=/usr --shared --install

Or install in your home with meson + ninja:

$ sys/ --prefix=$HOME/r2meson --local --shared --install


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

$ make uninstall
$ make purge

To remove all stuff including libraries, use

$ make system-purge

Package Manager

Radare2 has its own package manager - r2pm. Its packages repository is on GitHub too. To start to using it for the first time, you need to initialize packages:

$ r2pm init

Refresh the packages database before installing any package:

$ r2pm update

To install a package, use the following command:

$ r2pm install [package name]


Coding Style

Look at



make tests
will fetch the test binaries repository and run all the tests in order to verify that no changes break any functionality.

We run those tests on every commit, and they are also executed with ASAN and valgrind on different platforms to catch other unwanted 'features'.
