Security researchers and red teamers who need to analyze malware and firmware will find Radare2 invaluable for its scriptable disassembly and its command-line efficiency across Linux, Windows, and macOS without licensing friction. With 22,210 GitHub stars and active development, the community-driven framework covers binary analysis end-to-end: disassembly, debugging, and patching all in one tool. Skip this if your team needs GUI-first workflows or expects vendor support; Radare2 has a steep learning curve and rewards operators who think in assembly and Python, not point-and-click analysts.
