About this tool
Fair questions
What does this check analyze?
We analyze your domain for technology stack (framework, CMS, server), performance metrics (Core Web Vitals), security headers (CSP, HSTS, X-Frame-Options), infrastructure (hosting, CDN), SSL/TLS configuration, caching headers, and JavaScript weight.
Is it safe? Will you crawl my site?
Completely safe. We only read your HTTP headers and publicly available HTML. We do not crawl your content, collect data, or perform any invasive analysis. Analysis is fast and read-only.
What should I do with the results?
Use the score and recommendations as a starting point. If you score below 75, there are clear wins available. Most opportunities fall into: performance optimization, adding security headers, updating dependencies, or improving infrastructure/caching.
Does this work for internal/private sites?
Only for publicly accessible domains. If your site requires authentication or is behind a firewall, we cannot analyze it.
