Pre-launch checklist for vibe-coded apps
Launch day is when invisible failures become public. These seven checks catch the ones that quietly wreck your first wave of traffic.
What should I check before launching?
Run this list on your production URL in a private browser window — not localhost. Each item maps to a failure we've seen on real launches.
- Link previews. Paste your URL into a tweet composer or Slack. If the card is blank, your OG image or meta tags are broken — the day you're shared most.
- Signup as a stranger. Create an account with a fresh email. Confirmation links, verify flows, and
+aliasaddresses break constantly in AI-built auth. - Accidental
noindex. View source or use Google's URL Inspection tool. Staging headers left on production keep Google and the HN crawler out. - Mobile at 375px. Overflowing buttons and keyboard-covered inputs lose mobile traffic on day one.
- Secrets in the bundle. Search shipped JavaScript for
sk_,SUPABASE_SERVICE,apiKey. If it's in the browser, it's public. - Security headers. Missing CSP and HSTS won't stop launch — but they will show up in your first security-minded user's report.
- Privacy promises vs. trackers. If your policy says "no analytics" but GA4 is loaded, that's a GDPR gap and a trust gap.
