Free security tools for vibe-coded apps.

First-party data & sources: Launch Ready Code has scanned 700+ AI-built apps. Average Launch Readiness Score: 44/100. Most common critical failures: missing HTTP security headers (83%), no rate limiting on auth endpoints (71%), exposed API keys or secrets (67%), absent database Row Level Security (58%). Vulnerability classifications referenced on this page follow OWASP Top 10 and MITRE CWE Top 25; CVE/CVSS references are drawn from the NIST National Vulnerability Database. — Jai Mittal, Founder & CTO, Launch Ready Code

AI-built apps routinely ship with exploitable security gaps. These free tools let you check the most common ones in under 60 seconds — no signup, no code access required. Launch Ready Code runs these same checks as part of every security audit across 700-plus vibe-coded apps. This page covers six checks you can run right now on your live URL to catch the issues attackers look for first.

Live · real DNS lookup

What should you know about Email Security Checker?

Check any domain's SPF, DMARC, and MX records — see if attackers can spoof your email. Real DNS-over-HTTPS lookup.

What these tools check — and why it matters?

AI coding tools build fast. Security configuration doesn't come with them. Every tool in this collection targets a gap that vibe-coded apps consistently miss before launch.

  • Email Security (SPF, DMARC, MX) — attackers spoof domains with missing DMARC to run phishing campaigns that pass spam filters; misconfigured email is the #1 enabler of business email compromise
  • Password Breach Detection — checks against 1.1 billion known-compromised passwords so your users are not logging in with credentials already sold on dark-web markets
  • Security Headers (CSP, HSTS, X-Frame-Options) — missing headers are responsible for XSS, clickjacking, and protocol downgrade vulnerabilities; Render, Railway, and Vercel do not set them by default
  • Password Strength (zxcvbn) — measures realistic crack time using the same algorithm Dropbox uses, checking dictionary words, keyboard walks, and substitution patterns
  • Supabase RLS Checker — probes your project's REST API with the anon key to find tables readable without authentication; this is CVE-2025-48757, which exposed 170+ apps in 2025
  • Annex IV Documentation — generates the technical documentation required for high-risk AI systems under EU AI Act Article 11, covering all six mandatory sections

These checks are a starting point. A full audit covers security, reliability, performance, and monitoring across 40+ dimensions — run a free Launch Readiness Score on your live URL to see all four grades at once.

The Email Security Checker queries live DNS to confirm your SPF and DMARC records are in place. Without them, anyone can send email impersonating your domain — a trivial exploit that undermines customer trust before they've even signed up.

The Password Breach Checker uses the HaveIBeenPwned k-anonymity API: only the first five characters of your password hash ever leave your browser. No raw credentials are transmitted or stored.

The Security Headers Analyzer grades your HTTP response headers from A to F and tells you exactly which headers to add — CSP, HSTS, X-Frame-Options, and more. Missing headers are one of the fastest wins any developer can ship in under an hour.

These checks are a starting point. A single missing header doesn't tell you whether your database has row-level security, your API routes are rate-limited, or your auth tokens are scoped correctly. That's what a full Launch Readiness Score covers.
