CST VerdictBased on our analysis of available product data, here is our conclusion:
Penetration testers and red team operators building custom packet manipulation tools will find Libcrafter's value in its Scapy-like API reducing development time for network attack tooling. The 311 GitHub stars and free pricing mean you're getting battle-tested code without licensing friction, though the C++ requirement means your team needs stronger systems programming skills than Python-based alternatives demand. Skip this if you need a polished GUI or enterprise support; Libcrafter is a library for operators who write code.
Red teamers and penetration testers who need to build custom attack chains will find Impacket indispensable; its Python-native SMB, Kerberos, and NTLM implementations let you craft protocol-level attacks that commercial tools either can't do or won't let you customize. The 14,800+ GitHub stars reflect real adoption in offensive engagements, and the library's low-level protocol handling means you can exploit edge cases that signature-based defenses miss. Skip this if your team wants a point-and-click interface; Impacket demands Python fluency and assumes you understand the protocols you're weaponizing.
