Live DoH Benchmark

Find your fastest DNS

Real-time DNS-over-HTTPS benchmark from your browser. Edge-proxied timing, no install, no data collected.

How this test works

This tool runs entirely in your browser, sending live DNS-over-HTTPS (DoH) queries from your local environment. No server-side code collects personal data.

Warm-Up Phase: Before timing each DNS server, the script primes connections and caches to minimize TCP/TLS handshake overhead.

Measurement: fetch and performance.now() measure full DoH round-trip times, including HTTP/TLS overhead.

Timeouts: Each query times out after 5 seconds with a 5000 ms penalty.

Variability: Network latency and browser load cause variability. Run multiple tests for a broader picture — results are best used as a relative comparison.
