Analyze software with Cutter, an open-source reverse engineering platform powered by Rizin.
About Cutter
Cutter is a free, open-source reverse engineering platform that uses Rizin as its core engine, exposing that engine's functionality through a graphical interface or an integrated terminal. It combines disassembly and a linear disassembly view, a graph view with mini-graph for navigation, a hex editor, binary patching, emulation, and a Python scripting engine that can be extended with native or Python plugins. Releases include native integration of Ghidra's decompiler without Java, and a multiplatform native and remote debugger for dynamic analysis that is marked beta. Cutter is licensed under GPLv3 and is intended for reverse engineers working on binary analysis, including malware analysis and crypto algorithms.
