Things people build with this

USE CASE 1

Analyze malware samples to understand their behavior and find vulnerabilities without running them.

USE CASE 2

Debug a compiled binary when you don't have access to the original source code.

USE CASE 3

Learn how programs work at the machine level by stepping through assembly code.

USE CASE 4

Reverse engineer proprietary software to understand its logic or recover lost functionality.

Getting it running

Difficulty · moderate Time to first run · 30min

Requires building C++ with Qt dependencies and Rizin/Ghidra integration; pre-built binaries may be available but source compilation is common.

Free and open-source; you can use, modify, and distribute it freely under the terms of the LGPL license.

In plain English

Cutter is a free, open-source graphical desktop application for reverse engineering, the practice of analyzing compiled software to understand how it works, find security vulnerabilities, or recover logic from a program when you don't have the source code. It is powered by rizin, a command-line reverse engineering framework, and wraps it in a visual interface so you can explore binary files without memorizing command-line syntax. The tool gives you a visual disassembler (which converts compiled machine code back into human-readable assembly instructions), a graph view of code flow, a debugger for stepping through programs, and a hex editor for inspecting raw bytes. It supports plugins written in Python or C++, including a native integration with the Ghidra decompiler, Ghidra being a separate reverse engineering tool from the NSA that can convert assembly back into approximate C code, which is much easier to read. You would use Cutter if you are a security researcher analyzing malware, a developer debugging a compiled binary you don't have source for, or a student learning how programs work at the machine level. It runs on Linux, macOS, and Windows. It is written in C++ and built on Qt for its graphical interface.
