Strix

Strix is an open-source, autonomous security testing platform aimed at continuous pentesting across an organization's entire stack. It automatically discovers and validates vulnerabilities across APIs, web applications, pull requests/code, infrastructure, and cloud environments, generates proof-of-concept exploits to confirm real exploitability rather than flagging noisy false positives, and can auto-fix issues by opening merge-ready pull requests. It integrates into CI/CD pipelines to block vulnerable deployments before they ship, and works with GitHub, GitLab, or Bitbucket alongside AWS, Google Cloud, Azure, and Kubernetes. Offers a free self-service tier plus paid and enterprise plans (self-hosted deployment, SLAs, SOC 2 Type II / ISO 27001 compliance). Over 46,000 GitHub stars.
