## What it is
rev.ng is an open-source binary analysis framework and decompiler built on LLVM and QEMU, supporting over 20 CPU architectures. It automatically recovers data structures, function prototypes, and emits readable C code, with a declarative YAML-based workflow and a VSCode-based UI.

## Use cases
- decompile a compiled binary back to C code
- analyze malware or unknown executables without source
- recover structs and data types from stripped binaries
- disassemble and inspect ELF, PE, and Mach-O files
- lift binaries across 20+ CPU architectures via QEMU
- script binary analysis pipelines using YAML models
- import IDA databases and DWARF/PDB debug info

## When to choose
- you need a free, open-source decompiler alternative to IDA/Ghidra
- you want automatic interprocedural struct and array recovery
- you need multi-architecture support leveraging QEMU
- you prefer scriptable, declarative (YAML) analysis workflows

## When to avoid
- you need a mature GUI-centric reversing workflow with a large plugin ecosystem today
- you require fully offline standalone UI, which is still in closed beta
- you only need quick static string/entropy triage rather than deep decompilation

## Facets
- artifact type: framework
- maturity: active
- function: reverse-engineering, compiler, interpreter, developer-tools, security
- domain: reverse-engineering, security, developer-tools, compilers
- platform: windows, cpp, cross-platform
- tags: decompiler, binary-analysis, llvm, qemu, disassembler, struct-recovery, yaml-driven, linux, macos
