ROPgadget is a Python CLI security tool that statically scans executable binaries for ROP, JOP, and SYS gadgets. It discovers architecture-specific byte patterns (x86/x64, ARM/ARM64, MIPS, PowerPC, SPARC, RISC-V), disassembles candidate regions with Capstone, and outputs address/instruction listings. It supports ELF, PE, Mach-O, raw, and universal/fat binaries, and offers filtering by mnemonic, regex, bad bytes, address ranges, and call-preceded gadgets. For x86/x64 ELF targets it can also generate a Python exploit script that chains gadgets into a ROP payload.
