r2pipe

r2pipe is a set of language bindings that enables external programs to control radare2, the reverse-engineering framework. By providing a uniform API across languages, r2pipe lets developers script analyses, automate tasks, and integrate radare2 features into other tools. It communicates with radare2 either by launching it as a child process or by connecting to an existing session, using radare2's RPC mechanism to exchange commands and results.

Bindings exist for Python, JavaScript (Node.js), Ruby, Go, C, C++, Java, PHP, and more, reflecting the project’s emphasis on interoperability. The bindings expose methods to send commands to radare2 and to receive results, including JSON-formatted responses. Typical usage involves issuing commands through a cmd interface and, when JSON is requested, cmdj to obtain structured data.

r2pipe is part of the radare2 ecosystem and is widely used in tooling, scripting, security research, and education. It supports both interactive sessions and batch processing, enabling integration into IDEs, build scripts, and CTF workflows. As an open-source component, it is maintained by the radare2 community and ecosystem.
