Rematch, a simple binary diffing framework that just works.
At least, we hope it will be. Rematch is still a work in progress and is not fully functional at the moment. We’re currently working on bringing up basic functionality. Check us out again soon or watch for updates!
Rematch is intended to be used by reverse engineers for revealing and identifying previously reverse engineered similar functions, and then migrating documentation and annotations to current IDB. Rematch does that by locally collecting and uploading data about functions in your IDB. Rematch uploads information to a web service (which you’re supposed to set up as well), that upon request, is able to match your functions against all (or part) of existing database of previously uploaded functions and provide matches.
A secondary goal of rematch (which is not currently pursued) is to allow synchronization between multiple reverse engineers working on the same file.
Goal of Rematch¶
The goal of Rematch is to act as a maintained, extendable, open source tool for advanced assembly function-level binary comparison and matching. Rematch will be a completely open source and free (as in speech) community-driven tool. We support buttom-up organizational methods and desire Rematch to be heavily influenced by it’s users (both in decision making and development).
We’ve noticed that although there are more than a handful of existing binary matching tools, there’s no one tool that provides all of the following:
- Open source and community driven.
- Supports advanced matching algorithms (ML included ™).
- Fully integrated into IDA.
- Allows managing multiple projects in a single location.
- Enables out of the box one vs. many matches.
- Actively maintained.

In particular, we’re having trouble with implementing a stylish web interface for the rematch server, enriching this documentation and the testing framework. Engine suggestions (and obviously PRs) are extremely welcome, as well as feature requests. We tend to be permissive about approving PRs, but you can always raise an issue or discussion about a feature before implementing it.
