DoH Performance Tester

Query any domain across multiple DNS-over-HTTPS providers simultaneously. Compare response times, check DNSSEC validation, and see who resolves your queries fastest.

DNSSEC Validation

Each query checks the AD (Authenticated Data) flag in the DNS response to verify DNSSEC signing chain integrity.

Latency Measurement

Response times are measured from your browser to each provider's DoH endpoint using the Performance API. Results vary by your location.

100% Client-Side

All queries are sent directly from your browser to each DNS provider. Nothing passes through our servers. Your queries are private and encrypted via HTTPS.
