Open-source AI Hackers for your apps

Strix

Open-source AI Hackers to secure your Apps

[!TIP] New! Strix now 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!

🦉 Strix Overview

Strix are autonomous AI agents that act just like real hackers - they run your code dynamically, find vulnerabilities, and validate them through actual proof-of-concepts. 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 hacker toolkit out of the box
• 🤝 Teams of agents that collaborate and scale
• ✅ Real validation with PoCs, not false positives
• 💻 Developer‑first CLI with actionable reports
• 🔄 Auto‑fix & reporting to accelerate remediation

🎯 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)
• Python 3.12+
• An LLM provider key (e.g. get OpenAI API key or use a local LLM)

Installation & First Scan

# Install Strix
pipx install strix-agent

# Configure your AI provider
export STRIX_LLM="openai/gpt-5"
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>

☁️ Run Strix in Cloud

Want to skip the local setup, API keys, and unpredictable LLM costs? Run the hosted cloud version of Strix at app.usestrix.com.

Launch a scan in just a few minutes—no setup or configuration required—and you’ll get:

• A full pentest report with validated findings and clear remediation steps
• Shareable dashboards your team can use to track fixes over time
• CI/CD and GitHub integrations to block risky changes before production
• Continuous monitoring so new vulnerabilities are caught quickly

• Injection Attacks - SQL, NoSQL, command injection
• Server-Side - SSRF, XXE, deserialization flaws
• Client-Side - XSS, prototype pollution, DOM vulnerabilities
• Business Logic - Race conditions, workflow manipulation
• Authentication - JWT vulnerabilities, session management
• Infrastructure - Misconfigurations, exposed services

🕸️ Graph of Agents

Advanced multi-agent orchestration for comprehensive security testing:

💻 Usage Examples

Basic Usage

# Scan a local codebase
strix --target ./app-directory

# Security review of a GitHub repository
strix --target https://github.com/org/repo

# Black-box web application assessment
strix --target https://your-app.com

Advanced Testing Scenarios

# 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

# 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 ./instruction.md

🤖 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.

strix -n --target https://your-app.com

🔄 CI/CD (GitHub Actions)

Strix can be added to your pipeline to run a security test on pull requests with a lightweight GitHub Actions workflow:

name: strix-penetration-test

on:
  pull_request:

jobs:
  security-scan:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      - name: Install Strix
        run: pipx install strix-agent

      - name: Run Strix
        env:
          STRIX_LLM: ${{ secrets.STRIX_LLM }}
          LLM_API_KEY: ${{ secrets.LLM_API_KEY }}

        run: strix -n -t ./

⚙️ Configuration

export STRIX_LLM="openai/gpt-5"
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

OpenAI's GPT-5 (openai/gpt-5) and Anthropic's Claude Sonnet 4.5 (anthropic/claude-sonnet-4-5) are the recommended models for best results with Strix. We also support many other options, including cloud and local models, though their performance and reliability may vary.
