Snowman is a native code to C/C++ decompiler, supporting x86, AMD64, and ARM architectures. You can use it as a standalone GUI application, command-line tool, IDA plug-in, or a library. Snowman is free software.
Clone the repository, follow the build instructions, run the decompiler. Alternatively, download the prebuilt packages, unpack, and run.
We are not done yet. We want better generated code, even more convenient GUI, support for other architectures. Feel free to pick a problem, solve it, and send a pull request. Write to our mailing list if you have questions.
