Strix

The open-source AI pentesting tool. Autonomous AI hackers that find and fix your app’s vulnerabilities.

[!TIP] New! Strix integrates seamlessly with GitHub Actions and CI/CD pipelines. Automatically scan for vulnerabilities on every pull request and block insecure code before it reaches production - Get started with no setup required.

Strix Overview

Strix are autonomous AI penetration testing agents that act just like real hackers - they run your code dynamically, find vulnerabilities, and validate them through actual proofs-of-concept. Built for developers and security teams who need fast, accurate security testing without the overhead of manual pentesting or the false positives of static analysis tools.

Key Capabilities:

Full pentesting toolkit - reconnaissance, exploitation, and validation out of the box
Multi-agent orchestration - teams of AI pentesters that collaborate and scale
Real exploit validation - working PoCs, not false positives like legacy vulnerability scanners
Developer‑first CLI - actionable findings with remediation guidance
Auto‑fix & reporting - generate patches and compliance-ready pentest reports

Use Cases

Application Security Testing - Detect and validate critical vulnerabilities in your applications
Rapid Penetration Testing - Get penetration tests done in hours, not weeks, with compliance reports
Bug Bounty Automation - Automate bug bounty research and generate PoCs for faster reporting
CI/CD Integration - Run tests in CI/CD to block vulnerabilities before reaching production

🚀 Quick Start

Prerequisites:

Docker (running)
An LLM API key from any supported provider (OpenAI, Anthropic, Google, etc.)

# Install Strix
curl -sSL https://strix.ai/install | bash

# Configure your AI provider
export STRIX_LLM="openai/gpt-5.4"
export LLM_API_KEY="your-api-key"

# Run your first security assessment
strix --target ./app-directory

[!NOTE] First run automatically pulls the sandbox Docker image. Results are saved to strix_runs/<run-name>

☁️ Strix Platform

✨ Features

Agentic Pentesting Tools

Strix agents come equipped with a comprehensive offensive security toolkit - the same tools used by professional penetration testers and ethical hackers:

HTTP Interception Proxy - Full request/response manipulation and analysis with Caido
Browser Exploitation - Automated browser for testing XSS, CSRF, clickjacking, and auth bypass flows
Shell & Command Execution - Interactive terminal for exploit development and post-exploitation
Custom Exploit Runtime - Python sandbox for writing and validating proof-of-concept exploits
Reconnaissance & OSINT - Automated attack surface mapping, subdomain enumeration, and fingerprinting
Static & Dynamic Code Analysis - SAST + DAST capabilities for comprehensive application security testing
Vulnerability Knowledge Base - Structured findings with CVSS scoring and OWASP classification

Comprehensive Vulnerability Scanner

Strix identifies, validates, and exploits a wide range of security vulnerabilities across the OWASP Top 10 and beyond:

Broken Access Control - IDOR, privilege escalation, auth bypass
Injection Attacks - SQL injection, NoSQL injection, OS command injection, SSTI
Server-Side Vulnerabilities - SSRF, XXE, insecure deserialization, RCE
Client-Side Attacks - XSS (stored/reflected/DOM), prototype pollution, CSRF
Business Logic Flaws - Race conditions, payment manipulation, workflow bypass
Authentication & Session - JWT attacks, session fixation, credential stuffing vectors
Infrastructure & Cloud - Misconfigurations, exposed services, cloud security issues
API Security - Broken authentication, mass assignment, rate limiting bypass

Graph of Agents (Multi-Agent Pentesting)

Advanced multi-agent orchestration for comprehensive automated penetration testing:

Distributed Pentesting - Specialized AI agents for recon, exploitation, and post-exploitation
Scalable Security Testing - Parallel execution across multiple targets for fast, comprehensive coverage
Dynamic Coordination - Agents share discoveries, chain vulnerabilities, and collaborate like a red team

# Grey-box authenticated testing
strix --target https://your-app.com --instruction "Perform authenticated testing using credentials: user:pass"

# Multi-target testing (source code + deployed app)
strix -t https://github.com/org/app -t https://your-app.com

# White-box source-aware scan (local repository)
strix --target ./app-directory --scan-mode standard

# Focused testing with custom instructions
strix --target api.your-app.com --instruction "Focus on business logic flaws and IDOR vulnerabilities"

# Provide detailed instructions through file (e.g., rules of engagement, scope, exclusions)
strix --target api.your-app.com --instruction-file ./instruction.md

# Force PR diff-scope against a specific base branch
strix -n --target ./ --scan-mode quick --scope-mode diff --diff-base origin/main

Headless Mode

Run Strix programmatically without interactive UI using the -n/--non-interactive flag - perfect for servers and automated jobs. The CLI prints real-time vulnerability findings and the final report before exiting. Exits with non-zero code when vulnerabilities are found.

          LLM_API_KEY: ${{ secrets.LLM_API_KEY }}

        run: strix -n -t ./ --scan-mode quick

[!TIP] In CI pull request runs, Strix automatically scopes quick reviews to changed files. If diff-scope cannot resolve, ensure checkout uses full history (fetch-depth: 0) or pass --diff-base explicitly.

export STRIX_LLM="openai/gpt-5.4"
export LLM_API_KEY="your-api-key"

# Optional
export LLM_API_BASE="your-api-base-url"  # if using a local model, e.g. Ollama, LMStudio
export PERPLEXITY_API_KEY="your-api-key"  # for search capabilities
export STRIX_REASONING_EFFORT="high"  # control thinking effort (default: high, quick scan: medium)

[!NOTE] Strix automatically saves your configuration to ~/.strix/cli-config.json, so you don’t have to re-enter it on every run.

Recommended models for best results:

OpenAI GPT-5.4 - openai/gpt-5.4
Anthropic Claude Sonnet 4.6 - anthropic/claude-sonnet-4-6
Google Gemini 3 Pro Preview - vertex_ai/gemini-3-pro-preview

See the LLM Providers documentation for all supported providers including Vertex AI, Bedrock, Azure, and local models.
