Description
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 alerts1,400+ downloads in first week.Quick start: pip install dns-benchmark-tool dns-benchmark compare --domain google.comCLI stays free forever. Hosted version (multi-region, historical tracking, alerts) coming Q1 2026.GitHub: https://github.com/frankovo/dns-benchmark-tool Feedback: https://forms.gle/BJBiyBFvRJHskyR57Built with Python + dnspython. Open to questions and feedback!

Could you build this?
Yes A DNS benchmarking CLI sending parallel UDP/DoH queries across known public DNS IPs to measure response times and calculate statistics can be quickly built with standard libraries.
Discussion
20 comments analyzed.
Competitors mentioned: ISC Looking Glass (DNS lookup snapshots), dnsdiag (DNS packet-level diagnostics), Gibson's GRC DNS Benchmark (GUI-based testing), etcd (service discovery)
Concerns raised: GPTSlop quality in code/service offering, Blocklist-based resolvers can be slower, Raw speed alone doesn't capture systemic DNS issues
Feature requests: Docker image for easier setup

Same idea, different domain
Nobody's really built a observability & eval tool for Media & entertainment yet.
