Why AI-Built Apps Fail at Launch (And How to Catch It Early)
Speed from Cursor or Lovable is real, but the last mile is where leaked keys, broken CTAs, and missing legal pages show up.
AI coding tools like Cursor, Lovable, v0, and Bolt have collapsed the gap between idea and deployed app from weeks to hours. That speed is real. What they do not automatically ship, however, is launch hygiene: HTTPS everywhere, working signup flows, privacy links, professional metadata, and secrets that stay off the client bundle.
We see the same five categories of failure on almost every fresh app we check. None of them are exotic. All of them are visible from a public URL within seconds.
The five recurring failures
- Leaked secrets. Stripe, Supabase, OpenAI, and Resend keys end up in client bundles because an env example got copy-pasted into a React component.
- Broken primary CTA. The hero button points to /signup, but /signup does not exist yet or returns a 404 from the framework default.
- Missing legal pages. The footer links to /privacy and /terms, but both render the Next.js 404. Reviewers and Product Hunt voters notice.
- Placeholder metadata. The browser tab still says “Create Next App” and the Open Graph image is missing, so social previews are blank.
- Insecure transport. The app loads over HTTPS, but a hardcoded http:// image, font, or API call triggers a mixed-content warning in the console.
Why this happens with AI-built apps specifically
Generative tools are excellent at producing the happy-path screen you described. They are less reliable at producing the surrounding scaffolding: the legal pages you did not ask for, the env hygiene you did not explain, the favicon you forgot existed. Each of those omissions is small. Stacked on a launch day, they read as carelessness.
A five-minute preflight
- Open your production URL in an incognito window and click every link in the nav and footer.
- Open DevTools → Network and reload. Look for any http:// request or any response with a key-shaped string.
- View source on the homepage and search for sk_, api_key, AKIA, and SUPABASE_SERVICE.
- Drop the URL into a free readiness report to catch the categories you would not think to check manually.
A five-minute preflight before you post on Product Hunt or send a client link is dramatically cheaper than an emergency key rotation at midnight, and it is the difference between a launch that looks intentional and one that looks rushed.
Focus on what strangers can see from your public URL. That is exactly what LaunchReadyCheck tests: no install, no account, just the URL.
