HTTP headers analyzer
What the server actually returns: redirects, indexing, cache, compression, security, and TTFB before/after cache.
Analyze a URL
HTTP headers control things invisible in the HTML: indexing (X-Robots-Tag), canonical, cache (Varnish/CDN), compression. This tool reads them, follows redirects, and measures TTFB before and after cache.
How it works
- Enter a URL: the tool follows its redirect chain (re-checking each hop).
- It reads the final response headers and groups them by theme.
- It measures TTFB twice to gauge the server cache.
What you get
- Redirects, X-Robots-Tag, header canonical, Content-Type.
- Cache (Cache-Control, Age, x-cache, Vary), compression, security.
- TTFB first view vs repeat view, and CDN/Varnish detection.
Bulk redirects to test?
The Redirects Checker analyzes a list of 301 redirects (chains, loops, flattening).
