Immunity Debugger

Immunity Debugger is a powerful new way to write exploits, analyze malware, and reverse engineer binary files. It builds on a solid user interface with function graphing, the industrys first heap analysis tool built specifically for heap creation, and a large and well supported Python API for easy extensibility.

EDB (Evan's Debugger)

EDB (Evan's Debugger) is a Qt4 based binary mode debugger with the goal of having usability on par with OllyDbg. It uses a plugin architecture, so adding new features can be done with ease. The current release is for Linux, but future releases will target more platforms.

Cutter

Cutter goal is to be an advanced FREE and open-source reverse-engineering platform while keeping the user experience at mind. Cutter is created by reverse engineers for reverse engineers. - Powered by radare2: Cutter is using radare2 as its core engine. Thus, allows access to thousands of features via the GUI or by using the integrated terminal.

REDasm

REDasm is an interactive, multiarchitecture disassembler written in C++ using Qt5 as UI Framework. Its core is light and it can be extended in order to support new instructions and file formats.
