## What it is
XELFViewer is a GUI application for viewing and editing ELF (Executable and Linkable Format) binary files on Windows, Linux and macOS. It is part of the NTInfo suite of binary analysis tools by horsicq.

## Use cases
- inspect ELF binary headers and structures
- edit fields in an ELF executable
- analyze Linux binaries during reverse engineering
- view ELF64 program and section headers
- triage suspicious ELF malware samples

## When to choose
- you need a cross-platform GUI to inspect or edit ELF files
- you are doing reverse engineering or malware analysis of Linux binaries
- you want a lightweight alternative to full disassemblers for header inspection

## When to avoid
- you need to analyze PE or Mach-O files (use XPEViewer or XMachOViewer instead)
- you need disassembly or decompilation rather than structure viewing
- you require scripted headless ELF parsing

## Facets
- artifact type: application
- maturity: active
- function: reverse-engineering, parser
- domain: reverse-engineering, security, developer-tools
- platform: windows, cross-platform
- tags: elf, binary-analysis, viewer, hex-editor, gui, linux, macos
