We’re excited to announce that ONE Platform has achieved exceptional Lighthouse scores: 100/100 on desktop and 97/100 on mobile. This isn’t just a number—it represents a commitment to providing the fastest, most accessible web experience possible.
Desktop Performance: 100/100
Our desktop performance is flawless across all metrics:
- ✅ Performance: 100/100
- ✅ Accessibility: 100/100
- ✅ Best Practices: 100/100
- ✅ SEO: 100/100
Desktop Metrics
| Metric | Score | Target | Status |
|---|---|---|---|
| First Contentful Paint (FCP) | 0.3s | < 1.8s | ✅ 6x faster |
| Largest Contentful Paint (LCP) | 0.7s | < 2.5s | ✅ 3.6x faster |
| Total Blocking Time (TBT) | 0ms | < 200ms | ✅ Perfect |
| Cumulative Layout Shift (CLS) | 0 | < 0.1 | ✅ Perfect |
| Speed Index | 0.4s | < 3.4s | ✅ 8.5x faster |
Result: Desktop users experience near-instantaneous page loads (0.3s FCP!) with zero layout shifts.
Mobile Performance: 97/100
Achieving near-perfect mobile scores is significantly harder than desktop, and we’re at 97/100:
- 🟢 Performance: 97/100
- ✅ Accessibility: 100/100
- ✅ Best Practices: 100/100
- ✅ SEO: 100/100
Mobile Metrics (Simulated Slow 4G)
| Metric | Score | Target | Status |
|---|---|---|---|
| First Contentful Paint (FCP) | 1.4s | < 1.8s | ✅ 1.3x faster |
| Largest Contentful Paint (LCP) | 2.5s | < 2.5s | ✅ At target |
| Total Blocking Time (TBT) | 0ms | < 200ms | ✅ Perfect |
| Cumulative Layout Shift (CLS) | 0 | < 0.1 | ✅ Perfect |
