Next.js launch checklist

Is your Next.js app ready to launch?

App Router, Server Components, and Vercel defaults hide a lot of launch blockers — missing security headers, broken metadata on dynamic routes, and exposed env vars in client bundles. Run a clearance scan on your production URL.

Security & headers

Production deploys need baseline HTTP hardening before you share the URL.

  • Enable HSTS with a max-age of at least six months on your production domain.

    Audit check SEC-001 · security

  • Add a Content-Security-Policy — Next.js inline scripts and third-party widgets often need a tuned policy.

    Audit check SEC-003 · security

  • Set X-Frame-Options or frame-ancestors in CSP to prevent clickjacking on auth and billing pages.

    Audit check SEC-005 · security

  • Scan client bundles for exposed API keys — NEXT_PUBLIC_* and leaked server secrets in .next/static.

    Audit check SEC-020 · dns ssl

SEO & discoverability

Metadata, crawlability, and structured data that search and AI systems rely on.

  • Every marketing and docs route needs a unique title and meta description — watch dynamic [slug] pages.

    Audit check SEO-001 · seo

  • Open Graph and Twitter card tags must resolve on share URLs — test /blog/[slug] and landing pages.

    Audit check SEO-004 · seo

  • Submit sitemap.xml and verify canonical tags don't conflict between www and apex.

    Audit check SEO-010 · seo

  • Add Organization or WebSite JSON-LD on the homepage for rich results.

    Audit check SEO-015 · seo

Performance

Core Web Vitals and load behavior under real traffic — not just localhost.

  • Largest Contentful Paint under 2.5s on mobile — optimize hero images and font loading in layout.tsx.

    Audit check PERF-001 · performance

  • Cumulative Layout Shift under 0.1 — reserve space for dynamic imports and cookie banners.

    Audit check PERF-002 · performance

AI visibility

Help ChatGPT, Claude, Perplexity, and Google AI cite your product accurately.

  • Publish /llms.txt describing your product, docs, and pricing for AI crawlers.

    Audit check AIV-001 · ai visibility

  • Confirm GPTBot and ClaudeBot are not blocked in robots.txt if you want AI citations.

    Audit check AIV-002 · ai visibility

FAQ

Next.js launch questions

Does Launch Auditor scan Next.js App Router sites?

Yes. Launch Auditor crawls your live production URL regardless of framework. It detects Next.js via technology fingerprinting and applies checks for headers, metadata, performance, and client-side secret exposure common on Vercel deploys.

Should I scan preview URLs or production?

Scan the exact URL you will share publicly. Preview deployments often lack production headers, DNS, and analytics — clearance on staging does not guarantee production readiness.
