Can Launch Auditor audit a client-only React SPA?
Yes. The crawler loads your app in a real browser, executes JavaScript, and checks rendered DOM for metadata, accessibility, and performance — not just static HTML.

React SPA launch checklist
React app shipped — but is it launch-ready?
Create React App, Vite, and custom SPAs often ship without server-side security headers, proper meta tags for client routing, or accessible form labels. Audit the live build before you drive traffic.
Security & headers
Production deploys need baseline HTTP hardening before you share the URL.
Configure HSTS and redirect HTTP to HTTPS at your CDN or reverse proxy — SPAs rarely set this in-app.
Audit check SEC-001 · security
Deploy a Content-Security-Policy that restricts script-src — React apps often load third-party analytics.
Audit check SEC-003 · security
Ensure X-Content-Type-Options: nosniff is set on static asset responses.
Audit check SEC-006 · security
SEO & discoverability
Metadata, crawlability, and structured data that search and AI systems rely on.
Use react-helmet or SSR meta injection so /pricing and /signup have unique titles — crawlers don't run your router.
Audit check SEO-001 · seo
Prerender or SSR critical landing routes — blank index.html hurts social previews and AI crawlers.
Audit check SEO-003 · seo
Verify favicon and apple-touch-icon load from the production CDN path.

Performance
Core Web Vitals and load behavior under real traffic — not just localhost.
Code-split routes and defer non-critical bundles — measure LCP on the heaviest dashboard view.
Audit check PERF-001 · performance
Audit third-party script impact on Total Blocking Time.
Audit check PERF-005 · performance
Accessibility
Client-rendered forms and modals are a common WCAG failure point.
All inputs need associated labels — placeholder-only fields fail axe scans.

Verify color contrast on primary buttons and error states.
