## What it is
angr is a Python 3 binary analysis framework that loads executables across many architectures and formats, providing disassembly, IR lifting, control-flow recovery, decompilation, and symbolic (concolic) execution. It ships as a suite of libraries plus angr-management, the official GUI.

## Use cases
- solve CTF reverse-engineering challenges with symbolic execution
- decompile a binary to C pseudocode
- recover control-flow graphs from stripped executables
- analyze malware or firmware binaries across CPU architectures
- find inputs that reach a target code path in a program
- perform backward slicing and data-dependency analysis on binaries

## When to choose
- you need scriptable, cross-architecture static and dynamic binary analysis in Python
- you want symbolic execution or constraint solving over native binaries
- you're solving CTF reversing challenges or doing vulnerability research
- you need CFG recovery or decompilation without IDA/Ghidra licenses

## When to avoid
- you only need a quick interactive disassembly of one binary - a GUI disassembler may be simpler
- you need source-level (not binary) analysis or debugging
- you're analyzing managed languages like Java or C# where dedicated tools fit better
- you want a polished end-user reverse-engineering GUI rather than a programmable framework
