CST VerdictBased on our analysis of available product data, here is our conclusion:
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.
.NET developers and security researchers doing adversarial code review need ILSpy because it's the only free decompiler that actually handles modern C# constructs and async patterns without mangling the output. Its 24,766 GitHub stars reflect adoption by practitioners who've rejected paid alternatives; the tool's modular frontend architecture means you can pipe decompiled IL into custom analysis scripts instead of staring at a GUI. Skip this if your threat model requires decompiling obfuscated assemblies at scale; ILSpy struggles with commercial packers and gives up where commercial tools like dnSpy push through.
