Show HN: DNS Benchmark Tool – Compare and monitor resolvers
ovo101 Wednesday, November 19, 2025
I built a CLI to benchmark DNS resolvers after discovering DNS was adding 300ms to my API requests.
v0.3.0 just released with new features: compare: Test single domain across all resolvers top: Rank resolvers by latency/reliability/balanced monitor: Continuous tracking with threshold alerts
1,400+ downloads in first week.
Quick start: pip install dns-benchmark-tool dns-benchmark compare --domain google.com
CLI stays free forever. Hosted version (multi-region, historical tracking, alerts) coming Q1 2026.
