IDA Pro vs radare2

IDA Pro is a disassembler, decompiler and debugger for analyzing processors, file formats and software. It supports disassembly for more than 60 processor families, and its debugger works with multiple targets, including remote applications. The bundled gooMBA plug-in uses algebraic and program-synthesis techniques, heuristics and an SMT solver to simplify obfuscated binaries. Automation options include the IDA C++ SDK, IDAPython API, IDAT command-line functions and the idalib headless library. Teams can work with GitHub, GitLab, Bitbucket, Gitea or another Git remote, with Git LFS support for large IDB files. Private Lumina is a self-hosted add-on that restricts a knowledge base to authorized users; it exchanges function hashes and metadata rather than entire byte patterns. IDA Pro runs on Linux, macOS and Windows. The IDA Pro Essential plan costs $1,099 a year, with a one-year minimum commitment and no monthly payments. Hex-Rays states that there is no free trial and points users to IDA Free for checking basic capabilities.

radare2 is a free, UNIX-like reverse-engineering framework and command-line toolset for working with binaries across many architectures. It can analyze, emulate, debug, modify, and disassemble binaries, as well as support 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 plugins include r2ghidra, r2frida, r2yara, and r2pipe. The project identifies iaito, a Qt graphical interface, as its official GUI. Installation options include the Git repository, released binaries, Nix packaging, and source builds. Most of radare2 is licensed under LGPLv3, while dependencies and plugins may have different licenses. It supports operating systems including Windows, Linux, macOS, iOS, Android, BSD, and others, alongside a broad range of architectures.
