Strix

Also known as: usestrix/strix, Strix AI pentest, Strix agent

An open-source multi-agent AI penetration testing tool that behaves like an ethical hacker: it runs your application dynamically, chains exploits, and validates every finding with a working proof-of-concept before reporting it. Hit number one on GitHub Trending in July 2026.

Traditional security scanners flag potential issues based on pattern matching against known vulnerability signatures. Strix works differently: it deploys a team of AI agents that reason about a target application the way a human attacker would, exploring it dynamically, discovering attack paths, and then proving each finding with a working proof-of-concept exploit. No PoC, no reported finding.

The tool ships with a full offensive toolkit including an HTTP proxy, browser automation, a Python sandbox for exploit development, and shell access. It integrates with CI/CD pipelines (GitHub Actions, GitLab CI) so security testing can run on every pull request rather than as a quarterly exercise. It supports any LLM backend, including local models via Ollama for air-gapped environments.

Strix reached roughly 39,000 GitHub stars by mid-July 2026, making it one of the fastest-growing security repositories in GitHub history. For builders, it represents a category shift: agentic AI moving from productivity tooling into security workflows. One important ground rule applies everywhere it's discussed: only point it at systems you own or are authorized to test. Autonomous exploitation agents aimed at unauthorized targets are illegal, not just frowned upon.
