In their own words
REHex
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.
