Open-source AI hackers to find and fix your app’s vulnerabilities.

What is Strix?
Strix is an autonomous AI security testing platform for applications, APIs, cloud, and infrastructure. It uses AI agents that behave like real attackers: they run code dynamically, explore targets, find vulnerabilities, and validate them with proof-of-concepts rather than just flagging possible issues.
The product is built around fast, practical security testing for developers and security teams. Its documentation highlights use cases such as application security testing, rapid penetration testing, bug bounty automation, and CI/CD integration to block vulnerabilities before production.
A key part of Strix is its agent-driven workflow. Specialized agents collaborate across a graph-based architecture, combining reconnaissance, browser automation, HTTP proxying, terminal access, Python runtime execution, and code analysis to investigate targets deeply.
It is designed for both interactive and automated use. You can run it through a developer-first CLI with a text UI or headless mode, target local codebases, GitHub repositories, domains, IPs, or web apps, and tune scan depth from quick to deep depending on how thorough you want the assessment to be.
Strix pricing
Pricing model: Freemium
The website says you can start for free, and the project is also described as free on GitHub. The public site and docs do not show paid plan tiers or a detailed pricing table for the core Strix security product, so the visible pricing information is effectively a free-start model with no published paid-plan breakdown on the homepage.

Frequently asked questions about Strix
What does Strix do?
Strix is an autonomous AI security testing platform that runs against code, APIs, cloud, infrastructure, websites, domains, IPs, and repositories. It dynamically explores targets, finds vulnerabilities, and validates them with proof-of-concepts so users can separate real issues from false positives.
How is Strix different from static scanners?
Strix emphasizes live validation instead of only pattern matching. Its documentation says it behaves like a real attacker, uses dynamic execution, and confirms findings with PoCs, which is meant to reduce false positives compared with static analysis tools.
Who is Strix for?
Strix is built for developers and security teams. Its use cases also point to bug bounty hunters and auditors who want faster penetration testing, automated research, and detailed vulnerability reporting.
What can Strix scan?
The CLI and docs say Strix can scan web applications, GitHub repositories, local directories or codebases, domains, and IP addresses. The homepage also frames the platform as covering code, APIs, cloud, and infrastructure.
Does Strix support CI/CD workflows?
Yes. The docs explicitly mention CI/CD integration, and the CLI includes a non-interactive mode designed for automation. In that mode, scans can run headlessly and exit automatically when finished.
What tools do the agents use?
Strix agents come with a toolkit that includes browser automation, an HTTP proxy, terminal access, a Python runtime, reconnaissance capabilities, and code analysis. The platform says these tools help agents manipulate requests, test auth flows, develop exploits, and map attack surfaces.
What kinds of vulnerabilities can Strix find?
The documentation lists access control issues like IDOR and privilege escalation, injection issues like SQL and command injection, server-side problems such as SSRF and XXE, client-side issues like XSS and DOM vulnerabilities, authentication weaknesses, business logic flaws, and infrastructure misconfigurations.
How does Strix handle multi-step testing?
Strix uses a multi-agent architecture where specialized agents collaborate on different parts of the target. The docs say this allows distributed workflows, dynamic coordination, and parallel execution for broader coverage across complex targets.
How do you start using Strix?
The quick start shows installation through a shell installer, then setting STRIX_LLM and LLM_API_KEY environment variables, and finally running a scan with the strix command. Example usage includes scanning a local app directory after configuration.
Is there a public API?
Yes. The API documentation says Strix provides programmatic control over pentests, vulnerabilities, schedules, and webhook automations. It supports actions like starting or rerunning pentests, downloading reports, managing vulnerability workflows, and subscribing to lifecycle events.
