Summary

radare2 is a free, UNIX-like reverse-engineering framework and command-line toolset for analyzing binaries across many architectures. It can emulate, debug, modify, and disassemble binaries, and it also supports firmware analysis and decompilation. The tools can edit local files, view kernel memory, and debug programs locally or through remote GDB and WinDbg servers. Scripting is available through an embedded JavaScript interpreter or r2pipe. Its r2pm package manager searches for, installs, updates, and uninstalls plugins and tools; listed integrations include r2ghidra, r2frida, r2yara, and r2pipe. The project identifies iaito as its official Qt graphical interface. Installation options include the Git repository, released binaries, Nix packaging, and source builds. Most of radare2 is licensed under LGPLv3, though dependencies and plugins may have different licenses. It supports operating systems including Windows, Linux, macOS, iOS, and Android, alongside many others.
