GuardianScan - Find out why your site is slow, not ranking, or inaccessible—47 checks in 45 seconds with specific fixes

The Challenge

After conducting 500+ website audits between 2010 and 2025, a pattern emerged: modern frameworks were evolving faster than audit tools. Lighthouse checks performance. WAVE covers accessibility. Screaming Frog handles SEO. But no single tool checked what actually matters in 2025—Core Web Vitals, WCAG 2.2, framework-specific issues, and semantic HTML for AI search engines. Developers and agencies needed something that could check all of this in under 60 seconds without juggling five different tools.

  • Complete each audit in under 60 seconds (target: 45s)
  • Check 6 categories: Performance, Security, Accessibility, SEO, AI Search, Code Quality
  • Detect framework-specific issues (Next.js, React patterns)
  • Report actionable fixes, not arbitrary scores
  • Scale from free tier (1 scan/month) to agency tier (unlimited team access)
  • Be honest about limitations (~70% accessibility coverage, not 100%)

The Solution

Built a parallel processing engine that runs 47 checks across 6 categories in roughly 45 seconds. Google Lighthouse handles the performance and accessibility foundation. Custom checks cover framework-specific issues, security headers, and semantic HTML structure (for ChatGPT and Perplexity). Speed mattered more than checking everything—focus on what breaks sites in 2025, not legacy browser bugs from 2015.
