Hiew vs rev.ng

Hiew is a Windows console program for viewing and editing files of unlimited size in text, hex, and disassembler modes. Its maker describes it as a classic since 1991. Disassembly includes x86-64 with AVX instruction support and an ArmV6 disassembler. Listed executable formats include NE, LE, LX, PE/PE32+, little-endian ELF and ELF64, Mach-O, and TE/TE64. Users can follow direct calls and jumps with a click and search instruction patterns in disassembler mode. Other listed capabilities include block operations, multi-file search and replace, keyboard macros, Unicode and UTF-8, binary templates, scripting, disk editing, plugins, and HEM modules. The free demo omits editing, crypt, assembler, 64-bit and ARM disassembly, drive support, keyboard macros, and HEM support, among other restrictions. The single-version license costs $25 as a one-time purchase with no updates. Lifetime updates cost $249 as a one-time purchase; Hiewix 32-bits costs $59, paid once with free 1-year updates.

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.
