Features, pricing, ratings, and pros & cons — compared head-to-head.
Havoc Framework is a free offensive security tool. Merlin 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 NIST CSF 2.0 coverage, core features, company size fit, deployment model, here is our conclusion:
Red teams and penetration testers building custom C2 infrastructure will find Havoc's malleable profiles and team collaboration features faster to operationalize than Cobalt Strike, especially at zero cost. The 8,200-plus GitHub stars reflect active community contribution to payload obfuscation and evasion techniques that actually work against modern defenses. Skip this if your priority is managed C2 services or Windows-only operations; Havoc's strength is flexibility for operators who want to own their implant behavior, not outsource it.
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.
