Core Web Vitals

Enter a URL to get a quick performance snapshot. Fetches basic metadata, response time, and simulated Core Web Vitals scores.

How it works

URL is fetched server-side
HTML metadata is extracted
Response time (TTFB) is measured
Simulated CWV scores are computed

Limitations

• CWV are server-estimated, not lab data
• CORS-blocked sites may not load
• Rate limited: 10 requests / minute
