Diaphora is a free and open source program diffing (binary diffing) tool that works as an IDA Pro plugin, comparing binaries to find changed functions, port symbols, and detect patched vulnerabilities. It is written in Python and actively maintained, supporting IDA 7.4 through 9.4.

Use cases

• diff two binaries to find what changed between versions
• detect potentially fixed vulnerabilities via patch diffing
• port function names, comments, structs and enums between IDA databases
• find similar functions across binaries with heuristics
• automate batch binary diffing for malware analysis
• generate pseudo-code patches for changed functions

When to choose

• you use IDA Pro and need to compare two versions of a binary
• you analyze security patches to identify fixed vulnerabilities
• you need to transfer analysis work (symbols, comments, types) between IDB files
• you want a free alternative to BinDiff with advanced heuristics

When to avoid

• you need to diff binaries without IDA Pro (exported databases only for CLI diffing)
• you need diffing for non-binary source code
• you require a fully GUI-independent workflow for initial database export
