Partial The UI and rule-based scanning workflow can be vibe-coded, but a credible scanner needs accurate, broad security rules across many frameworks and backends, which requires security expertise to get right.
What it would actually take: Build a CLI or web tool that parses project files (routes, auth middleware, env files, database schemas) and runs deterministic rule checks. The hard part is writing and validating a comprehensive, low-false-positive rule set for each framework and BaaS platform, such as Supabase RLS, Firebase rules, and Next.js or Express auth patterns. That requires security engineering knowledge and real-world test corpora.
