Incident responders and malware analysts who need to reverse-engineer obfuscated Python binaries will find uncompyle6 invaluable; it's the only actively maintained decompiler that handles multiple Python versions and recovers readable source from compiled .pyc files that other tools choke on. With 4,241 GitHub stars and consistent commits, it's proven in real forensics workflows where time spent reconstructing logic from bytecode directly impacts investigation speed. Skip this if your team works primarily in compiled languages like Go or Rust, or if you need a graphical disassembler; uncompyle6 is command-line only and Python-specific.
