## What it is
Rehex is a cross-platform hex editor designed for reverse engineering binary files, with features like large file support, inline disassembly, binary templates, and Lua scripting. It runs on Windows, Linux, macOS, and BSD.

## Use cases
- inspect and edit binary files in hex
- reverse engineer file formats and firmware
- disassemble machine code inline
- compare two binary files side by side
- annotate byte ranges with comments and highlights
- decode integer and float values from raw bytes
- script binary analysis tasks with Lua
- apply binary templates to auto-annotate structures

## When to choose
- you need a GUI hex editor for reverse engineering on Windows, Linux, or macOS
- you work with very large (1TB+) binary files
- you want binary templates, disassembly, and scripting in one tool
- you need Intel HEX import/export or checksumming

## When to avoid
- you only need a lightweight CLI hex dump tool like xxd or hexdump
- you need a full disassembler/decompiler like Ghidra or IDA
- you require plugin ecosystems beyond Lua scripting
