## What it is
Detect It Easy (DiE) is a cross-platform file type identification tool that uses signature-based and heuristic analysis to detect compilers, packers, and file formats like PE, ELF, Mach-O, APK, and archives. It features a flexible, script-driven detection system popular with malware analysts and reverse engineers.

## Use cases
- identify what compiler or packer was used to build a binary
- detect file types of unknown executables
- analyze malware samples during reverse engineering
- check entropy of a file to spot packing or encryption
- identify PE, ELF, Mach-O, APK, and archive formats
- write custom detection signatures for new file formats

## When to choose
- you need fast, accurate file type and packer identification across Windows, Linux, and macOS
- you are doing malware analysis or digital forensics and need customizable detection rules
- you want a free, actively maintained alternative to tools like PEiD or ExeinfoPE

## When to avoid
- you need deep dynamic analysis or debugging rather than static file identification
- you require automated decompilation or disassembly output
- you need a library-only solution without a GUI or CLI
