radare2 vs rev.ng

radare2 is a free, UNIX-like reverse-engineering framework and command-line toolset for working with binaries across many architectures. It can analyze, emulate, debug, modify, and disassemble binaries, as well as support firmware analysis and decompilation. The tools can edit local files, view kernel memory, and debug programs locally or through remote GDB and WinDbg servers. Scripting is available through an embedded JavaScript interpreter or r2pipe. Its r2pm package manager searches for, installs, updates, and uninstalls plugins and tools; listed plugins include r2ghidra, r2frida, r2yara, and r2pipe. The project identifies iaito, a Qt graphical interface, as its official GUI. Installation options include the Git repository, released binaries, Nix packaging, and source builds. Most of radare2 is licensed under LGPLv3, while dependencies and plugins may have different licenses. It supports operating systems including Windows, Linux, macOS, iOS, Android, BSD, and others, alongside a broad range of architectures.

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.
