Our Pre-Launch Checklist for Every Web Product

Launches are stressful. A checklist makes them less so.

Performance

• Lighthouse score above 90 on mobile
• Images are WebP or AVIF, with explicit width/height attributes
• Fonts are preloaded; no layout shift on load
• Bundle size reviewed — no accidental large dependencies

Security

• HTTPS enforced, HSTS header set
• Content Security Policy configured
• Environment variables confirmed — no secrets in client code
• Dependencies audited with npm audit or equivalent

SEO & Metadata

• Every page has a unique title and meta description
• Open Graph tags set for social sharing
• robots.txt and sitemap generated
• Canonical URLs configured

Monitoring

• Error tracking set up (Sentry or equivalent)
• Uptime monitoring active
• Core Web Vitals baseline captured before launch

Accessibility

• Keyboard navigation tested
• Screen reader walkthrough completed for key flows
• Colour contrast passes WCAG AA

Rollback plan

Before any launch, we define exactly how we’d roll back if something goes wrong. A plan that exists only in your head is not a plan.

The goal isn’t a perfect launch — it’s a recoverable one.
