Lighthouse Audits
Measures Performance, SEO, Accessibility and Best Practices scores for every page — powered by Google Lighthouse v13. Individual Lighthouse HTML reports are included in the final merged PDF.
Security & Accessibility
Runs Mozilla Observatory and OWASP ZAP for security headers and vulnerability detection, plus axe-core and Pa11y for WCAG accessibility violations — all in a single pass.
Full-Site Crawling
Discovers all pages automatically via sitemap, built-in Go crawler, Screaming Frog SEO Spider, or wget spider — no manual URL list needed.
Rich Report Formats
Generates a complete merged PDF (cover report + all Lighthouse page reports), interactive HTML dashboard, Markdown summary, and raw Lighthouse JSON — all in one run.
Four report formats, zero extra work
Every audit produces a ready-to-share folder with everything your team needs.
