Forensics investigators and malware analysts who need to reverse-engineer proprietary binary formats without writing custom parsers should reach for Kaitai Struct. A single declarative schema compiles into working parsers across Python, C++, Java, and seven other languages, cutting weeks of manual parsing work to hours. Skip this if your team lacks developers comfortable with domain-specific languages or if you need a GUI-driven point-and-click tool; Kaitai requires code literacy and integrates into workflows, not replaces them.
