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.
Check any domain's SPF, DMARC, and MX records — see if attackers can spoof your email. Real DNS-over-HTTPS lookup.
Open tool → Live · privacy-safeSee if a password has appeared in known breaches — checked via k-anonymity, so your password never leaves your browser.
Open tool → Live · instant gradePaste your response headers and get an A–F grade with the exact headers to add (CSP, HSTS, X-Frame-Options, and more).
Open tool → Live · 100% in-browserTest a password's strength and estimated crack time. Runs entirely client-side — nothing is sent anywhere.
Open tool → EU AI Act · Article 11Generate compliant Annex IV technical documentation for high-risk AI systems under EU AI Act Article 11. Download as PDF.
Open tool → EU AI Act · Article 4Free 4-module EU AI Act literacy training for your team. Satisfies Article 4 requirements with signed staff acknowledgements and certificates.
Open tool → Live · instant checkProbe your public Supabase endpoint for tables readable without authentication — the #1 way AI-built apps leak other users' data. Get the exact policy to add.
Open tool →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.
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.
A free tool tells you about one gap. A Launch Readiness Score tells you if your whole app is ready — across security, reliability, performance, and monitoring — in about 60 seconds.
