## What it is
BinDiff is an open-source comparison tool for binary files that finds differences and similarities in disassembled code using graph-theoretical matching. It integrates with disassemblers like IDA Pro, Binary Ninja, and Ghidra, and includes a Java-based visual diff UI.

## Use cases
- diff two binaries to find changed functions
- identify vulnerability fixes in vendor patches
- port function names and comments between disassemblies
- find similar functions across different binaries
- compare malware variants
- gather evidence of code theft

## When to choose
- you need to compare two versions of a compiled binary
- you analyze patches to isolate security fixes
- you want to transfer analysis work between binary versions
- you need function-level matching across architectures like x86, ARM, MIPS

## When to avoid
- you need to diff source code rather than binaries
- you have no access to a supported disassembler (IDA Pro, Binary Ninja, Ghidra)
- you need automated large-scale binary analysis pipelines without a GUI
