Hextor vs REHex

Hextor is a free Windows hexadecimal editor and toolkit for analyzing binary data. It can present content as text, hexadecimal, integer, or floating-point values, and can interpret or edit data through C-like structure descriptions. Search and replace supports text, hex, Unicode, wildcards, and value searches. Binary comparison detects inserted and deleted data. Hextor can view and edit logical volumes, physical disks, and process memory. Analysis features include bitmap viewing, MD, SHA, and CRC hash calculation, plus a disassembler using the Zydis library. Scripting works through IActiveScript. Version 0.15 adds partial, view-only Intel HEX support and searches involving an unknown half-byte. The Freeware plan costs nothing and allows personal and commercial use. Source code is available only for review. The project advises caution and backups for valuable data, provides no warranty, and disclaims liability for damage from use.

REHex is a free hex editor for reverse engineering and other work with binary data, available for Linux, macOS and Windows. It supports files larger than 1 TB, decodes integer and floating-point values, and displays machine-code disassembly inline. Users can compare whole files or selected regions side by side, map virtual addresses, and highlight or annotate byte ranges. Editing and analysis tools include bit editing, checksumming and bitmap visualization, along with common encodings such as ASCII, Unicode and ISO-8859-X. REHex imports and exports Intel HEX files. Binary Templates can annotate data automatically, while Lua scripting and plugins extend its functionality. Downloads include Windows installers and ZIP archives, a macOS DMG, and 32-bit and 64-bit Linux AppImages; packages are also documented for Debian, Ubuntu, Fedora, Red Hat Enterprise Linux, FreeBSD and openSUSE. The project identifies its license as GPL-2.0. The download page lists version 0.64.0, released on 2026-04-03, as the latest release. Bug reports and feature suggestions can be submitted as GitHub issues.
