Why ShipReady wins vs Mozilla Observatory
Full site audit vs security-only — ShipReady covers SEO, performance (Lighthouse), AI visibility, mobile readiness, and 90+ checks. Mozilla Observatory checks security best practices only.
AI visibility coverage — llms.txt, per-bot crawler access (GPTBot, ClaudeBot), schema.org, trust signals. Mozilla Observatory has none of this.
AI fix prompts — paste into Cursor or Claude Code immediately. Mozilla Observatory shows a score and grade but no code to fix issues.

Common questions about ShipReady vs Mozilla Observatory
Is Mozilla Observatory still relevant in 2026?
Mozilla Observatory remains a solid quick-check for HTTP security headers. ShipReady runs all the same security checks plus a full Lighthouse audit, AI visibility (llms.txt, AI crawlers, schema.org), SEO audit, and generates AI fix prompts for every issue — making it a complete replacement for Observatory plus much more.
Does ShipReady score the same security headers Mozilla Observatory does?
Yes. ShipReady checks CSP, HSTS, X-Frame-Options, X-Content-Type-Options, Referrer-Policy, and all headers Mozilla Observatory covers. It also adds SSL Labs TLS grading, cookie security flags, and detection of exposed secrets that Observatory does not audit.
