CST VerdictBased on our analysis of available product data, here is our conclusion:
Red teamers and penetration testers running multi-stage engagements will find Merlin's HTTP/2 C2 framework invaluable for its lightweight Golang architecture and cross-platform flexibility, which sidesteps the detection signatures that plague Metasploit-based infrastructure. The 5,516 GitHub stars and active community contributions reflect real operational adoption, not theoretical interest. Skip Merlin if your team needs built-in evasion modules or OPSEC hardening out of the box; you're doing custom development here, which means smaller teams should budget engineering time accordingly.
Red teams executing multi-platform campaigns will value CrossC2 for doing one thing exceptionally well: extending Cobalt Strike's command-and-control infrastructure to Linux and macOS without rebuilding your entire operational toolkit. The 2,546 GitHub stars and active maintenance signal a tool that actually works in production red team environments, not just in labs. Skip this if your operations are Windows-only or if you need post-exploitation capabilities beyond payload delivery; CrossC2 is strictly a C2 extender, not a replacement framework.
