Binary Ninja is a modern, open-source reverse engineering platform designed for disassembling, decompiling, and analyzing binary files across multiple architectures. Developed by Vector 35 Inc., a company founded by former CTF team members, Binary Ninja Free provides a downloadable, locally run tool for non-commercial use or evaluation, supporting limited architectures such as x86 and x86_64. Ideal for cybersecurity researchers, malware analysts, and students, it provides a clean GUI and robust analysis without requiring cloud uploads, unlike Binary Ninja Cloud.
