A live, server-side timing breakdown — DNS, TCP connect, TLS handshake and time-to-first-byte — for the initial response of any public domain.
Website Speed Test
DNS, TCP connect, TLS and time-to-first-byte timing breakdown for the initial response.
Enter a domain above to run a real, live check.
Capabilities
What it checks
Full phase breakdown
DNS, connect, TLS and TTFB measured and reported separately.
Compression check
Flags whether gzip or Brotli response compression is enabled.
Performance Score
A weighted 0–100 score derived from the timing breakdown.
Why use it
Benefits
- Isolate whether slowness comes from DNS, TLS or the origin server itself.
- Confirm a CDN or caching change actually improved TTFB.
- Export the timing report as JSON for a performance review.
