rev.ng vs Rizin

rev.ng is a decompiler for reverse engineering that turns supported binaries into syntactically valid, standard-compliant C. Its data-structure recovery uses information across functions to identify linked lists, structs, arrays, and arrays of structs. The listed default architectures are x86, x86-64, ARM, AArch64, MIPS, and S390X; supported imports include ELF, PE/COFF, Mach-O, DWARF, PDB, and IDB. Users can define functions, edit prototypes, and rename items in YAML files, or interact through an HTTP API. The interface is described as available in a browser or standalone app, with cloud and standalone use offering the same experience. Collaborators can share a project URL; public projects include two collaborators. The rev.ng decompilation pipeline is Free Software, while the UI is intended for commercial cloud and standalone versions. The service is free and lists API, Linux, macOS, web, and Windows platforms. The site invites users to join a closed beta for the UI.

Rizin is a free, open-source framework for reverse engineering and binary analysis. Its tools include a disassembler, hexadecimal editor, debugger, binary inspection, emulation, and binary diffing. Command-line utilities support analyzing, disassembling, patching, comparing, searching, replacing, and visualizing data. Users can write scripts in languages including Python, Haskell, OCaml, and JavaScript. Cutter is Rizin’s official graphical interface and uses Rizin as its backend. The framework supports plugins, which rz-pm can compile and install; the package manager is described as early in development. Rizin can match unnamed functions against FLIRT signatures from sigdb to help identify common code in stripped binaries. The project also lists decompilation, firmware analysis, hybrid analysis, and a plugin API. Installation routes are provided for Linux, Windows, macOS, OpenBSD, and Android. The project says its work is currently in beta, and community discussion and support are available through Mattermost, Telegram, and IRC.
