Traditional Web vs STACKED.ID
Why generic WordPress, Wix, and Framer templates fail enterprise speed standards.
| Performance Metric | Standard Web Builders (WordPress/Wix) | STACKED.ID Next.js 15+ Edge Engine |
|---|---|---|
| Largest Contentful Paint (LCP) | 2.8s – 5.4s (Slow) | 0.08s (Sub-100ms Guaranteed) |
| Lighthouse Performance Score | 35 – 65 / 100 | 100 / 100 Certified |
| JavaScript Bundle Payload | 1.8MB – 4.5MB (Bloated) | 38KB – 65KB (Zero-JS Streaming) |
| Global Edge POPs | Single Origin Server | 300+ Global POPs (Vercel Edge) |
| Semantic HTML & Metadata | Unstructured Tags (Poor SEO) | Semantic HTML5 & Automated Open-Graph |
| Cumulative Layout Shift (CLS) | High Shift (Unstable) | 0.000 (Zero Layout Shift) |
