Quick Start

npm i -g @cyberstrike-io/cyberstrike@latest && cyberstrike

That's it. CyberStrike launches a TUI in your terminal, asks for your LLM provider and API key on first run, and you're ready to go. Tell it what to test — it handles reconnaissance, vulnerability discovery, exploitation, and reporting autonomously.

Already have a Claude Code or OpenAI subscription? CyberStrike's intelligence layer sits on top of your existing AI subscription. No separate API costs — your current plan powers an entire pentest toolkit.

Intelligence Layer

CyberStrike isn't just a wrapper around an LLM. It's an intelligence layer that transforms any AI model into an offensive security specialist.

How it works: When you connect your LLM provider, CyberStrike injects domain-specific context — OWASP testing methodology, vulnerability patterns, attack chain reasoning, and tool orchestration logic — into every interaction. The model doesn't need to know security; CyberStrike teaches it.

What the intelligence layer provides:

• Schema normalization — Structured output from any provider, regardless of response format differences
• Context guard — Prevents prompt leakage and keeps the agent focused on the current test phase
• Provider auto-detection — Automatically identifies your LLM endpoint and configures the optimal transport
• Tool orchestration — Chains security tools intelligently based on findings, not fixed scripts

150+ AI providers and 5,300+ models supported out of the box:

CyberStrike integrates with the entire AI ecosystem through 23 bundled SDK providers and 150+ providers via the models.dev catalog. Here are the core integrations:
