CST VerdictBased on our analysis of available product data, here is our conclusion:
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.
Incident responders and forensic analysts who need to extract message content from protobuf-encoded traffic without reverse-engineering schema definitions will find protobuf-inspector invaluable; it's one of the few free tools that handles this at all. The 1,113 GitHub stars and active maintenance suggest real adoption in environments where protobuf interception happens regularly. Skip this if your team exclusively works with schema-documented APIs or REST services; protobuf-inspector solves a narrow problem and doesn't pretend otherwise.
