r2diaphora is a port of Diaphora to radare2 and MariaDB. It also uses r2ghidra as decompiler by default, with support for other decompilers such as pdc.
Quoting from the original repository:
Diaphora (διαφορά, Greek for 'difference') version 2.0 is the most advanced program diffing tool, working as an IDA plugin, available as of today (2019). It was released first during SyScan 2015 and is actively maintained.
- r2diaphora requires radare2 to be installed in the local machine and a valid connection to a MariaDB server. If you don't have either of those refer to the respective software manual on how to install them.

pip install r2diaphora - Run
