I've been building websites for 15 years. I'm a perfectionist - both visually and technically - and got tired of going back and forth between different tools, manual checks, and documentation for every audit.
Built GuardianScan to run everything in under 45 seconds: - Core Web Vitals (LCP, INP, CLS) - WCAG 2.2 compliance - Security headers and CSP policies - Modern framework patterns - SEO and schema markup
47 checks total.
These standards exist for a reason. Google prioritises fast sites. Accessible sites reach more people. Secure sites build trust. When you meet modern standards, you see it in your traffic and conversions.
Stack: Next.js 15, React 19, Supabase, Browserless.io for headless Chrome.
Won't catch everything - automated accessibility gets about 70% of issues. But it's what I use before every deploy now.
