PreFlight
PreFlight is a specialized security review platform tailored for AI-built SaaS applications. It performs pre-launch audits that scan source code and configurations to identify vulnerabilities in critical areas: authentication flows, Stripe payment integrations, API route protections, secrets management, and data access controls, including Supabase Row Level Security. The service integrates directly with GitHub repositories and supports popular frameworks like Next.js, along with services such as Clerk and Auth.js, enabling a repo-aware review that understands the application's full stack context. PreFlight combines deterministic automated scanning with human expert review to minimize false positives and provide actionable findings. Each issue is reported with a severity rating, evidence from the codebase, and precise remediation instructions. Users can schedule audits according to their subscription tier, with options for continuous re-checks that verify fixes and monitor new code changes. The platform is designed to give fast-moving founders and development teams confidence that their AI-generated code is secure before customer exposure.
