Three open-source tools for checking AI-generated apps on security, browser QA and UI design
A DEV Community post urges developers to run three free, MIT-licensed open-source tools before shipping AI-generated apps to production. The first, vibe-shield, is a static security scanner with 92 rules that flags issues such as leaked Supabase service_role keys, unauthenticated Next.js API routes and IDOR bugs. The second, ghost-qa, uses headless Playwright to test a live app for console errors, failed network calls, mobile layout problems, small touch targets and accessibility gaps. The third, unslop, is a 72-rule UI design linter that removes generic AI-style visuals and exports design tokens for Tailwind, CSS and W3C formats. The post notes that all three are listed on the Official MCP Registry and work with tools including Claude Code, Cursor, Windsurf, OpenCode and VS Code.
