BinSync

Decompiler plugin for collaborative reverse engineering that records each analyst's work in a shared Git repository, one branch per user, so teammates can pull, push or auto-push changes across IDA Pro, Binary Ninja, Ghidra and angr-management. Synced artifacts are function headers (names, arguments and types), stack and global variables, structs, enums and comments, including user-defined types. It is built by mahaloz, the angr team and the SEFCOM research lab and is used by the Shellphish hacking team; scripting goes through the separate DecLib library.

Requirements & limits

  • Release at review: 5.15.4, published 2026-08-21 on PyPI and GitHub (with an IDA plugin ZIP); the reviewed main commit is one commit ahead, adding Ghidra comment sync and auto-push without a version bump. Install with pip and then binsync --install, which places the plugin in each decompiler; Binary Ninja also offers it in its plugin manager. Every setup needs Python 3.10+ and Git.
  • Supported hosts per the README: IDA Pro 8.4+ (older IDA versions need BinSync 4.10.1), Binary Ninja 2.4+, angr-management 9.0+ and Ghidra 12.0+ launched in PyGhidra mode. Support differs by decompiler: angr-management does not sync global variables, structs or enums, and although the Ghidra table marks every artifact as supported, the README text still calls Ghidra support early-stage and says to expect only minimal features such as name and comment syncing.
  • Collaborators share a Git repository and analyze the same binary, which each of them supplies. The optional extras add an auxiliary server and an AI user that applies DAILA prompt results to a project and requires an OpenAI API key; its changes are model output to be reviewed.
  • BSD-2-Clause. The README's term REAs means reverse-engineering artifacts and does not refer to the REA project. Nothing was installed and no projects were synced.
