Features, pricing, ratings, and pros & cons — compared head-to-head.
Havoc Framework is a free offensive security tool. Pupy 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 structured assessments need Pupy for its genuine cross-platform reach and minimal operational footprint; the 8,948 GitHub stars reflect active community maintenance that keeps payloads functional across Windows, Linux, macOS, and Android without the licensing friction of commercial C2 frameworks. The tool's strength is flexibility and cost, not operational security or defensive evasion,modern EDR will catch it unless you're actively managing MITRE ATT&CK tradecraft. This is not for teams that need polished UI, enterprise support, or built-in OPSEC features; it's for practitioners who know how C2 infrastructure works and want to customize every layer themselves.
