your open source local AI security lead. one command.
Swain is an innovative open-source security review tool designed specifically for developers integrating AI-generated code. It acts as a local, command-line security lead that inspects code written by AI models like Claude and Codex before deployment, ensuring no security vulnerabilities slip through. Unlike traditional SaaS solutions, Swain operates entirely locally without requiring new accounts or dashboards, making it ideal for privacy-conscious teams. It scans for critical issues such as authentication bugs, billing bypasses, hardcoded secrets, SQL injections, and XSS vulnerabilities. After analysis, Swain provides pinpointed, actionable feedback along with the exact command needed to fix each problem, streamlining the security review process and reducing deployment risks. Its unique approach combines the power of AI with local control, making secure AI-driven development accessible and efficient for software engineers and security-conscious teams alike.
