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.
wxHexEditor
wxHexEditor is a free hex and disk editor for examining and changing binary data, with a particular focus on large files on Linux. It uses 64-bit file descriptors and supports files or devices up to 2^64 bytes. The site reports about 25 MB of memory use with multiple files larger than 8 GB open, without copying the whole file into RAM. You can insert or delete bytes without creating a temporary file, compare binary files and merge nearby results, and use its integrated x86 disassembly. It can open devices on Linux, Windows, and Mac OS X for disk and sector editing; raw sector editing can be used to work on partition tables and filesystems or recover data. Other tools include many encodings, checksum functions, XOR operations, color tags, and saving selections as dump files. Downloads are listed for Linux, Mac Intel, and Win32. The latest release event listed on the home page is version 0.24 Beta, dated December 31, 2017. The site’s supported languages are English, Turkish, and partially Russian.
