PLCinject is a free offensive security tool. Charlotte is a free offensive security tool. Compare features, ratings, integrations, and community reviews side by side to find the best offensive security fit for your security stack.
Based on our analysis of available product data, here is our conclusion:
Offensive security teams and red teamers conducting PLC assessments need PLCinject for its surgical ability to inject call instructions directly into PLC logic blocks without destructive patching. The 99 GitHub stars and free availability signal active adoption by practitioners running live industrial penetration tests. This is a narrow tool; it's not for defenders building detection or resilience programs, and it assumes you already have access to the PLC and understand block-level instruction sets.
Red teamers and penetration testers who need reliable shellcode execution without triggering EDR will find Charlotte indispensable; its C++ implementation and undetected status across major security stacks give you consistent command execution where batch scripts and PowerShell fail. The 979 GitHub stars reflect active maintenance and real-world validation from operators who depend on it. This is not for blue teams or organizations evaluating defensive tools; Charlotte is purpose-built for offense and makes no attempt to hide that.
