ImHex
A Hex Editor for Reverse Engineers, Programmers
ImHex is a Hex Editor, a tool to display, decode and analyze binary data to reverse engineer their format, extract informations or patch values in them. What makes ImHex special is that it has many advanced features that can often only be found in paid applications. Such features are a completely custom binary template and pattern language to decode and highlight structures in the data, a graphical node-based data processor to pre-process values before they're displayed, a disassembler, diffing support, bookmarks and much much more. At the same time ImHex is completely free and open source under the GPLv2 license. Byte patching, patch management, Copy-Bytes-As-Array for many common programming languages, string and hex search, Bookmarks, Goto, Huge file support, variable column count, custom encodings and much more. ImHex includes a full custom C++-like pattern language that allows easy highlighting, decoding and analyzing of file formats. -

RetDec is a retargetable machine-code decompiler based on LLVM
The decompiler is not limited to any particular target architecture, operating system, or executable file format. ELF, PE, Mach-O, COFF, AR (archive), Intel HEX, and raw machine code supported. 32-bit: Intel x86, ARM, MIPS, PIC32, and PowerPC 64-bit: x86-64 supported. Demangling of symbols from C++ binaries (GCC, MSVC, Borland). Reconstruction of functions, types, and high-level constructs. Output in two high-level languages: C and a Python-like language. Generation of call graphs, control-flow graphs, and various statistics. Detection and reconstruction of C++ class hierarchies (RTTI, vtables). Signature-based removal of statically linked library code. Static analysis of executable files with detailed information. We currently support Windows (7 or later), Linux, macOS, and (experimentally) FreeBSD. An installed version of RetDec requires approximately 5 to 6 GB of free disk space. -

Capstone
Capstone disassembly/disassembler framework
Capstone is a disassembly framework with the target of becoming the ultimate disasm engine for binary analysis and reversing in the security community. Created by Nguyen Anh Quynh, then developed and maintained by a small community, Capstone offers some unparalleled features. Support multiple hardware architectures: ARM, ARM64 (ARMv8), Ethereum VM, M68K, Mips, MOS65XX, PPC, Sparc, SystemZ, TMS320C64X, M680X, XCore and X86 (including X86_64). Having clean/simple/lightweight/intuitive architecture-neutral API. Provide details on disassembled instruction (called “decomposer” by others). Provide semantics of the disassembled instruction, such as list of implicit registers read & written. Implemented in pure C language, with lightweight bindings for D, Clojure, F#, Common Lisp, Visual Basic, PHP, PowerShell, Emacs, Haskell, Perl, Python, Ruby, C#, NodeJS, Java, GO, C++, OCaml, Lua, Rust, Delphi, Free Pascal & Vala (ready either in main code, or provided externally by the community). -

Medusa
An open source interactive disassembler
Medusa is a disassembler designed to be both modular and interactive. It runs on Windows and Linux, it should be the same on OSX. This project is organized as a library. To disassemble a file you have to use medusa_text or qMedusa. Medusa requires the following libraries: boost >= 1.55 (system, filesystem, thread, date_time), OGDF (required git), and Qt5 >= 5.2 for the GUI. You also need CMake for compilation and a C++11 compiler (VS2015 update 2 on Windows). Git is optional but allows to clone remote repository for specific features. If you do not wish to install the various dependencies on your system, you can use this docker image instead. Even though it is working out of the box, you may want to customize it to suit your needs or for added security (e.g. restrict ssh access to public key authentication only). -
