Rizin logo


Rizin is a fork of the radare2 reverse engineering framework with a focus on usability, working features and code cleanliness.

Rizin is portable and it can be used to analyze binaries, disassemble code, debug programs, as a forensic tool, as a scriptable command-line hexadecimal editor able to open disk files, and much more!

To learn more on Rizin you may want to read the official Rizin book.

How to install

Look at install instructions on our web page.

How to build

Use meson to compile and install Rizin. Please make sure to get an updated meson (e.g. get it with pip install meson if your system does not provide one that is at least version 0.55.0).

Clone this repository:

$ git clone

Then compile and install with:

$ meson setup build
$ meson compile -C build
$ sudo meson install -C build

Now you can use rizin:

$ rizin
 -- Thank you for using rizin. Have a nice night!

To uninstall rizin, execute sudo ninja -C build uninstall.

Please have a look at for more information about building Rizin.


We very much welcome any kind of contributions, from typos, to documentation, to refactoring, up to completely new features you may think of. Before contributing, we would like you to read the file, so that we can all be on the same page.

Apart from the main tool rizin, there are also other tools tailored for specific purposes and useful for shell scripting or as separate standalone tools:

  • rz-bin - provides all kind of information about binary formats
  • rz-asm - a command-line assembler and disassemblers
  • rz-diff - a tool to compare two binaries as raw data or analyzed executables
  • rz-hash - allows to calculate different hashes or even encrypt data
  • rz-gg - a small "eggs" code generator useful for exploitation purposes
  • rz-find - binary analog of find tool, allowing to search patterns and bit masks
  • rz-sign - tool to create, convert and parse FLIRT signatures
  • rz-ax - a calculator and number format converter
  • rz-run - a tool that allows to specify running environment and arguments for debugged file


We provide a way to interact with Rizin from Python, Haskell, OCaml, Ruby, Rust, and Go languages through rzpipe. Other languages although not currently supported could be easily added.
