# DNS Speed Test

> Free, browser-based DNS-over-HTTPS speed test at https://dnsspeedtest.online/

## What it does

DNS Speed Test benchmarks 28+ DNS-over-HTTPS (DoH) servers directly from the user's browser to find the fastest DNS resolver for their specific location and network conditions.

## Key facts

- Runs entirely client-side — no server-side code, no data collection
- Tests DNS-over-HTTPS (DoH) servers using the fetch API and performance.now()
- Includes a warm-up phase to prime TCP/TLS connections before timing
- Each query has a 5-second timeout; failed queries receive a 5000ms penalty
- Results include min, median, average, and max response times per server
- Reliability scoring tracks success/failure ratios
- Users can add custom hostnames and custom DoH servers
- Open source under GPL-3.0: https://github.com/BrainicHQ/DoHSpeedTest
