What do people build with it?

USE CASE 1

Analyze a suspicious binary or malware sample visually without memorizing command-line reverse engineering syntax.

USE CASE 2

Use the Ghidra decompiler plugin inside Cutter to convert assembly code back into approximate C code that is much easier to read.

USE CASE 3

Step through an executable with the built-in debugger to understand or trace the logic of a compiled program.

USE CASE 4

Inspect raw bytes of a binary file with the hex editor to locate hardcoded strings, keys, or data.

The Ghidra decompiler plugin must be downloaded and installed separately to get C pseudocode output.

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.

Copy-paste prompts

Prompt 1

I downloaded a suspicious Windows executable and want to analyze it with Cutter. How do I open the file and navigate to the main function in the disassembler?

Prompt 2

Using Cutter with the Ghidra decompiler plugin, how do I decompile a specific function from a binary to readable C pseudocode?

Prompt 3

I'm working through a CTF reverse engineering challenge. Walk me through using Cutter to find a hardcoded password string in a compiled binary.

Prompt 4

How do I write a Python plugin for Cutter that automatically renames anonymous functions based on nearby string references?

Prompt 5

Help me set up Cutter on Linux and install the Ghidra decompiler integration step by step.
